Homemade rack for earmuffs. We make a stand for a grinder Homemade stand for a grinder

If you have ever worked with an angle grinder, then you already know all its shortcomings. The main thing in this case is not the high accuracy of cutting samples, if you do the work manually. The flow of such a problem is quite difficult, which is especially important when it is necessary to create several elements with the same general parameters.

If vibration and backlash are taken into account, then a stationary installation is, of course, more stable in operation. But buying a machine for industrial production can not be used for its intended purpose at home. So the simplest model of the machine will cost about 22,500 rubles.

But such equipment also has some disadvantages that can suggest that it is easiest to create a cutting machine using a frame and just a grinder. Factory production models of such machines are limited in use. For example, the model mentioned above can only cut 100 mm pipes. In domestic conditions, it is very often necessary to work in conjunction with samples of a better section. In addition, everyone has their own needs, so a certain model simply cannot fully satisfy them.

Factory appliances can be significantly changed, but most often this happens in conjunction with financial investments. In some cases, it is generally irrational and wrong to change the device. This will apply to equipment that is created from alloys that are difficult to machine. A self-made grinder machine is currently very often trying to create home craftsmen. To accomplish this task, you can use several methods at once. If you consider them in detail, you can come up with your own design.

Drawings of a cutting machine from a grinder

Before you start creating a machine from a grinder, you should prepare additional components and parts, which can be pipes or an angle grinder, which will fulfill the role handles and frames. It is best to strengthen the grinder on it, using a special metal plate for this. To create such a blank, you need to use a thick piece of iron; it will take about 30 minutes to create such a device.

A metal sample will be applicable as a support; it is best to weld a corner to such an object. The end of the lever should be installed on the axis, since the return stroke will be performed using a spring. If you create a cutting machine with the help of a grinder on your own, then as a result you can get equipment with a low weight, which can later be placed absolutely anywhere. In addition, the assembly of the device will not take place with significant financial costs, because all the necessary parts can be found in everyday life.

The second way to create a machine

Creating a machine using a grinder in this way will be a little more difficult, but the tool will provide more efficient accuracy in cutting materials. To work, you will need to create:

Desktop.
Ruler.
Special frame design.

The frame of the table should be welded from the corner and the channel. Special sheet metal can be used as a countertop, but in some cases use materials such as:

The decision on what material to use when creating will directly depend on the purpose for which you want to use such a device, as well as what schemes you will work with in the future. In the process of creating a machine from a grinder using this method, it is also necessary to create a frame structure, one part of which will be completely motionless and will serve as an additional support.

One part must be placed on the countertop and firmly fixed with special bolts and welding. The second structure will be connected to the first with hinges. The angle grinder itself will be installed on it, the position of which is easy to change on your own. To return the equipment to its original state, you need to use a special spring.

If you create a cutting machine from a grinder, then a ruler is also used to create it. With the help of the ruler, you can easily display overall dimensions all samples. For this, a separate tube or a piece of iron with marks and a movable marker is most often used.

Today, a large number of different models of machine tools have been developed. Sometimes the angle grinder is placed under the tabletop, and sometimes above the surface itself. If we talk about safety, then a do-it-yourself cutting machine, the drawings of which you can create completely yourself, is best placed on top, since this option will be more reliable.

A special cutout is made along a special line adjoining the disc in the angle grinder to the table top. If you have any knowledge in electrical engineering, then the inclusion should be done through a special magnetic starter, in which case the start button will be combined with a specialized pedal. Even when the operator's hands are busy, he will be able to stop the machine in any case with his foot.

When creating a cutting machine from a grinder on your own, the drawings should be carefully considered. Very often they help not to make unnecessary mistakes in the design of the device. It is very important to comply with all the rules safety technology. At that moment, as the assembly of the machine is completed, it should be run again, which will help to finally make sure that there is no beating of the disk itself. It should not touch the protective cover of the machine.

To create a cutting machine for metal, you may prefer to use the pendulum variety. At the first stage of creation, it is worth using profile pipes for this, which are good to use in the process of creating the pendulum frame. The metal profile is most often used for cantilever mounting; it can be supplemented with a special steel bar or a metal tire.

If the machine will use load-bearing platforms, the steel sheet must be completely cut to size. To the lever, which has the appearance of a section of a profile pipe, it is worth attaching a cross section by welding. At this time, it is worth following the perpendicularity of the mount.

A strobe is a special groove that should be cut in the wall to complete the laying of electrical cables and wires. The difficulty lies in the fact that the groove must always be of constant depth and width. Only in this case the wire will be laid evenly and the total mortar for laying will be much smaller.

A wall chaser is used quite rarely in everyday use, so it will be unequal to purchase it in the house. But it can be easily created on one's own, using for this scheme an angle grinder - the most famous angle grinder.

The main task in this case is to install two diamond discs on the grinder shaft with a total distance of less than one centimeter:

First, install the first disk and fasten it with a nut.
We install the second disk and also fasten it with a nut.
We check the total distance that has arisen between the two disks.
We install additional protection on the grinder.
Once again we check the quality of the device.

If for some reason you are unable to create two disks on the shaft, then the strobe can be easily cut through with a simple method with one installed disk. To do this, you just need to cut a second line of a parallel type.

Work with wall chasers should be carried out in the same room. During operation, a large amount of dust is generated. Even an ordinary respirator cannot save from it. In order to remove such a negative impact, it is worth creating a special protective cover that can hide several disks at once and will have a special pipe for connecting to a vacuum cleaner.

Such a device is available on electric jigsaws for assembling small sawdust. In some cases, fans of the rational use of the device add two or four rotating rollers to the casing. During the movement of wall chasers along the surface of the entire wall, they will move evenly¸ without creating any load on the person’s hands at this time.

To create such a design on a wide groove, it is worth making special bushings for disc mounts to the main spring. With such a wall chaser, you can easily create grooves for further pipe laying.

In this case, the protective cover must be made wider. On the casing of the wall chaser, wires, as well as on all pipes, it is worth installing an additional screw to adjust the level of immersion of the cutting tool inside the wall. In this case, the casing will include two parts at once, which will be connected to each other by a hinge and a node for adjusting the main immersion.

In some cases, there is a need to mill a hole in some surface, but there is no familiar miller nearby, and it’s impossible to find one. If at the same time you have an angle grinder - a grinder, then this will be a good solution to the problem. To do this, you need to choose a machine from two options - a movable table or a movable machine.

In the first case, it is worth fixing the material or the part that will be subject to the milling process, while the grinder is attached in a vertical plane to the frame itself. On the frame, it will be easy to shift the plate to which the angle grinder itself is attached to the left and right, forward, and also back. In another way, we can move the grinder in relation to the workpiece itself.

In the next version, the grinder will be firmly fixed, and the workpiece itself will begin to move along the analogue left and right, forward and backward. These will be the main directions for the implementation of the milling process. For milling along a certain axis up and down, it will be very easy to add such a device.

After selecting a specific machine, you can implement its creation. The only place where you have to involve a turner is holding the cutter itself. It is machined from a hexagon not less than a width of 16 millimeters, since it thread grinders about 14 millimeters. Collet holder. It is very easy to create and does not have strong beats. A simple cam chuck copes with this task much worse.

The main advantage of such machines, as with all machines created from a grinder, is that they can be modified back into a simple grinder. As a kind of milling cutter from a grinder, you can create a drill.

Pendulum Saw Features

Creating your own fixture for a grinder is quite easy. In this case, you do not even need to apply drawings. Enough that you will understand the principle that is in a particular machine. The pendulum type of saw based on the grinder cannot be called an exception. This is the same cutting machine, but its mass is divided into two parts.

At the same time, the saw is somewhat similar to a children's swing. There is a frame on the movable sleeve, and a special grinding machine is installed on it. In this case, any load combined with the trigger spring will become a counterweight.

Any suitable part can be used as a hinge. In this case, the hinge is made from simulated car hinges. Hinges have not been used in modern products for a long time, but they will fit the machine perfectly.

Angle grinder (angle grinder or angle grinder), which received the unofficial name "grinder" - one of the most common universal tools designed for abrasive processing of various metal, wood, stone products. It is “Bulgarian” because it first appeared in the USSR from Bulgaria, where it was produced at a factory in the city of Lovech. In order to perform various precise work with a grinder, many craftsmen make a stand for an angle grinder with their own hands.

The choice of material for the bed

In this case, the capabilities of the angle grinder are significantly expanded. By installing the grinder on a stationary structure, you can make a cutting machine that will accurately and at the right angle cut any profiles - corners, I-beams, metal pipes.

To cut metal, wooden, plastic sheets of large sizes, you should install the grinder on a moving carriage that moves along the guides. In this case, it is advisable to use metal corners as guides.

Angle grinder stand is available in a variety of designs. For its manufacture, a variety of materials and components can be used. It does not make sense to recommend any specific design, since each owner of the angle grinder will adapt the grinder to his requirements.

Profiled pipes can be used as starting materials for the device, as they are the most durable and reliable for this type of work. For guides, you can use corners, channels 5U or 6.5U.

For complex structures, you will need a welding machine, but it is easier to get by with screw connections. If the work does not require special accuracy, then the grinder can be used simply as a portable tool.

To perform precise work, for example, with a grinding nozzle, you may need a stationary fixture - a stand for an angle grinder (you can assemble a simple collapsible machine with your own hands, which after use will be folded and hidden in the place allotted for it). Such a frame is sometimes also made of wood. It is advisable to make a wooden frame if frequent and prolonged use of angle grinders is not expected.

What may be needed to make a bed

Before you start making a frame for an angle grinder, you should decide what types of work this machine will perform. A do-it-yourself angle grinder stand can be much more functional than industrial products. Of great importance is the type of attachment of the angle grinder on the frame - vertical or horizontal. This has a lot to do with the depth of cut. The type of fastening also depends on the nature of the work performed.

For cutting materials on a stationary desktop, the angle grinder is mounted on a pendulum bracket made of corners or profiled pipes. If it is necessary to cut large sheets of steel, textolite, plywood, then the angle grinder is mounted on a movable carriage that moves along guides made of corners or channels. Having decided on the design, you should prepare the necessary tools and materials in advance.

Instruments:

Bulgarian;
drilling machine;
welding machine;
grinding wheel;
pliers;
screwdriwer set;
keys set;
measuring tools.

Materials:

steel corner 40×40;
steel corner 50×50;
channel 5U or 6.5U (for guides of a moving carriage);
cut water pipes;
profile pipes 15×15, 20×20, 25×25;
bearings;
hardware;
tin trim;
textolite.

How to make a simple rack for angle grinders with your own hands

Using the most common tools and using scrap materials, a simple do-it-yourself angle grinder stand can be made. To fix the grinder on the frame, you will need corners, metal or textolite plates. If two metal plates are used, the screws can be replaced with a welded joint. The plate, which serves as a mobile platform, is made of steel sheet or duralumin up to five millimeters thick.

If textolite is used instead of a metal sheet, then the workpiece should be up to ten millimeters thick. The second plate must be metal, as it serves as a stop. For the manufacture of steel is used with a thickness of five millimeters, since the main load is applied to it. Thinner metal cannot be used due to vibrations and possible deformation, which makes working with the device unsafe.

For reliable fixation on the platform, several through holes with a diameter of five millimeters are drilled on one half of the plate. The second half of the plate is marked so that then a hole with a diameter of eight millimeters is drilled in its center. All holes drilled in the platform are drilled from the back for countersunk screw heads. It is allowed to put a corner instead of the second plate, having drilled it accordingly.

If welding cannot be used, the angle or plate is firmly screwed to the platform so that the distance from the edge of the device to the cutting disc is at least five millimeters. In this case, the corner must be bent in relation to the rack by 60 °. To prevent the bolt from turning and vibration, the angle grinder is fixed in the upper part with a bolt with a Grover washer or a lock nut.

Pendulum cutting machine

The platform for the machine is made of sheet steel. For the pendulum lever, a profile pipe is suitable, to which the transverse shaft is welded strictly perpendicular. Two bearing units are rigidly pressed onto this shaft from both ends. After that, the pendulum is welded.

A bracket is made from a steel strip for fixing the angle grinder gearbox housing. For fastening, holes are drilled along the edges and in the center. To ensure rigid fixation of the body to the pendulum, a clamp is made from a steel bar. The metal clamping bar is fixed with bolts. The finished bracket, made in the form of the letter "P", is attached to the console.

The console with a clamp and a mount for the angle grinder is welded to the pendulum lever, at the same time a protective cover is installed. To automatically return the angle grinder to its original position, a return spring is used, which should be selected in accordance with the weight of the angle grinder.

After the machine is assembled, it must be turned on and at idle, check for vibrations and play. Then, with a cutting wheel of maximum thickness, cut a groove for the cutting tool. Stops for the main cut directions - 45° and 90° are bolted to the platform.

Sheet steel cutting machine

For cutting sheet steel, long sheets of textolite, chipboard with a grinder, a different design is needed. In this case, the angle grinder must be able to move along the processed material. This becomes possible if you fix the grinder on a movable carriage.

The carriage can be made on the basis of roller door blocks. Small corners or channels are used as guides. They are strictly parallel welded to the base. Instead of welding, a screw connection to the platform is possible, while the screws must be with a countersunk head, the nuts are fixed with Grover washers or locknuts.

Directly on the carriage, the angle grinder can be fixed rigidly or on the pendulum lever. The guides must be installed so that there is a gap between them and the work table to position the material being cut on the table.

Without an angle grinder - a grinder - you can not do it either in the garage or in a private courtyard. The unit allows you to cut a metal profile, clean a weld or remove rust from the surface of workpieces and parts, has a low price and incredible ease of use. The grinder also has disadvantages, one of which is the unstable quality of the cut and the danger of the cutting disc being skewed during use. You can eliminate annoying shortcomings by making a special frame with your own hands, which will turn a hand tool into a real cutting machine. This will increase the speed of work and achieve accuracy that can only be obtained on industrial equipment.

Scope of cutting machines

Cutting disc machines are widely used in metalworking, mechanical engineering, woodworking and furniture industries. The units have found their application in the household: they are used as a convenient tool for performing various work in the workshop and garage. The cutting machine is convenient to use for solving a number of tasks:

The advantages of disc cutting machines include convenience and ease of use, high cutting speed and accuracy, the ability to replace the cutting disc in a matter of minutes.

Due to the relatively low cost, universal units have a fast self-sufficiency, so it is advantageous to use them in small industries and small workshops.

In the household, a cutting machine is used irregularly, so buying a factory-made tool is irrational. It is better to make a special bed for an angle grinder. This will increase the versatility of the grinder, turning it into a small-sized cutting machine.

Types of devices, their advantages and disadvantages

There are two types of designs of cutting machines, differing in the location of the grinder, which can be made at home.

The first installation is a bed with an angle grinder rigidly fixed under it. On the working surface, only the cutting disc is visible, which freely passes into the slot of the table. Cutting a metal profile or sheet in this case is completely identical to sawing wooden blanks with a circular saw. Despite the very simple design, such a scheme is not particularly popular. Those who made such a device note the inconvenience in use due to the need to move the workpiece. This significantly reduces the accuracy of the work and makes the process unsafe. The only advantage of a machine with a bottom angle grinder is the ability to quickly cut thin metal sheets.

A cutting machine with a lower angle grinder can be used both for cutting metal and as a circular saw

The second scheme, in which the part remains stationary, and the cutting wheel itself moves, is more convenient. The so-called pendulum saw, located above the tabletop, allows you to cut the workpiece exactly at the required angle, while it becomes possible to make the required number of parts of the same type. Due to the location of the grinder on top, cutting workpieces does not require effort, and the operation of the unit becomes simple and safe. The undoubted advantages of the design include the ability to quickly dismantle the angle grinder for traditional use. As for the disadvantages of this method, the weak link can be considered a swivel, which complicates the design of the machine.

The machine for cutting metal with the top location of the grinder has a more convenient design and makes it possible to cut blanks at the desired angle

The device of a pendulum saw from a grinder

A pendulum saw from a grinder is available for assembly at home, does not require expensive materials and special skills. The cutting machine has a simple design and consists of several components:

bed;
pendulum;
fastening under the angle grinder.

The bed is a steel frame, welded from shaped pipes, with a platform made of sheet metal with a thickness of at least 3 mm. A bracket is attached to this plate, on which the hinge of the pendulum saw is mounted, as well as an emphasis to hold the workpiece. By the way, there can be several such stops: it is convenient when one element allows you to make a perpendicular cut, and the other makes it possible to cut the material at the required angle. The most perfect stop is a rotary device with a protractor, with the help of which any angle between the part and the cutting disc is set. An important detail: at the point where the saw touches the platform, a cut is made in the tabletop, its width should be equal to twice the thickness of the cutting circle, and the length should correspond to the diameter.

The standard design consists of a bed, a pendulum and a mount for an angle grinder

The pendulum of the cutting machine is a T-shaped piece made of a rectangular metal profile. On the one hand, this assembly is attached by a movable joint to the frame bracket, and on the other hand, a mount for a grinder is attached to it. The mobility of the hinge of the pendulum saw is provided by rolling bearings or bushings, and the return of the tool to its original position is provided by a flexible element (rubber band or spring).

The grinder mount is a console with one or two brackets connected to the pendulum. An angle grinder is attached to one of them with bolts. To do this, threaded holes are provided in the body of its gearbox for attaching the handle. The second bracket is a conventional clamp (ladder) that holds the cutting tool by the body.

Convenience in the operation of equipment can be significantly increased by connecting the angle grinder to a foot switch-pedal. Of course, in this case, the angle grinder start lever is brought into working position and fixed with a special button.

Necessary tools and materials

When starting to manufacture a cutting machine, it should be understood that the accuracy of its work is directly related to the stability of the structure. Therefore, the choice of a material of a certain thickness is dictated not so much by the requirements for the strength of the hull, but by the need for its rigidity.

Before starting work, you need to prepare:

profile pipe "square" (25x25x2.5 mm);
profile pipe "rectangle" (40x20x2.5 mm);
metal sheet 4–5 mm thick;
ball bearings No. 202, 203 or 204 - 2 pcs.;
a calibrated bar with a thickness equal to the diameter of the hole in the inner race of the bearing (up to 100 mm);
bar with a diameter of 8–10 mm;
metal tire (20x4 mm);
bolts and nuts with M8 or M thread.

Of the tools you will need:

Angle Grinder;
drill or drilling machine, a set of drills;
a set of dies for cutting metric threads;
wrenches;
welding machine.

The presence of electric welding is desirable, but not necessary - all connections can be made on threaded connections. However, it should be understood that this method reduces the reliability and strength of the structure.

For the manufacture of the machine, it is better to choose a grinder from a well-known manufacturer

The main unit of the cutting machine is the angle grinder. It is not recommended to use a "small" grinder, designed for cutting discs with a diameter of up to 125 mm with a power of up to 500-600 watts. Remember that the larger the diameter of the cutting wheel, the more versatile and reliable the machine will be.

The careful choice of power tools is also due to the wide variety of designs of angle grinders on the market. Since such equipment is not unified, the cutting machine is built for a specific model and size of the angle grinder. If the equipment is unreliable, then in case of failure it will be difficult to install another angle grinder in its place without the need to remake the mounts and the pendulum. That is why it is better to choose products from trusted manufacturers - Makita, Bosch and so on.

Making a cutting machine with your own hands

Preparatory stage

Work on a cutting machine begins with design. It is impossible to give the exact dimensions of the device, since the design depends on the model and size of the particular angle grinder. Nevertheless, according to the presented drawings, you can get an idea of the dimensions and structure of the equipment.

A project sketch begins with a hull drawing. You may not need a frame, but a separate platform that can be attached to a locksmith's workbench. In any case, the dimensions of the device and the location on the body of the main components are determined. Next, the angle grinder and the center distances of the mounting holes on the body of its gearbox are measured. Based on these indicators, a drawing is drawn up for attaching the grinder to the pendulum. After that, the rotary assembly itself is designed. The smaller the distance from the swivel to the cutting wheel, the stiffer and more accurate the machine will be. In other words, the length of the pendulum should be as short as possible.

At the last stage of the design, they calculate how much and what material will be needed.

Drawing cutting machine pendulum type. On the left are the dimensions of the base. The design features of the pendulum are marked on the right.

Step-by-step instruction

In accordance with the drawing, the blanks of the future machine are cut. Profile pipes are used for the frame and pendulum, and a metal profile, a metal tire and a steel bar are used for cantilever mounting. If the design provides for a carrier platform, then sheet steel with a thickness of 4–5 mm is cut to size.
A transverse axis (shaft) is welded to the pendulum lever, which is a section of a profile pipe, for a hinged connection. In this case, it is important to ensure the perpendicularity of the shaft attachment to the pendulum.
After cutting the material, a shaft is welded to the pendulum arm
A U-shaped bracket is bent from a steel tire, holes for bolts are drilled in its sides, with the help of which the gearbox housing of the angle grinder is attached.
For fastening to the threaded holes on the angle grinder gearbox housing, you will need a U-shaped bracket
An enveloping angle grinder U-shaped collar (ladder) and a clamping bar for fixing the tool body to the pendulum are made from a steel bar. The latter is a metal plate 15–20 mm longer than the clamp width. The threaded ends of the stepladder freely enter the holes on the edges of the pressure plate, and fixation is carried out with nuts with a suitable thread.
Trying on a U-shaped bracket and a clamp to the grinder, these parts are mounted on the console with a welding or threaded connection.
This is how the console for attaching the angle grinder to the pendulum arm assembly with a U-shaped bracket and clamp looks like
The bearings that will ensure the rotation of the pendulum are pressed into the supports. As the latter, you can use both ready-made factory bearing units and pieces of steel pipe (15–20 mm) with a diameter equal to the outer race of the bearing.
Bearing units are pressed onto the shaft from both sides. It is important that the connection is tight - this will eliminate unwanted longitudinal and transverse displacements. If the resulting connection is weakened for some reason, you can use the proven method - tin the axis with a soldering iron, applying a thin layer of tin to its surface (you will need soldering acid as a flux).
At a distance of 50–60 mm from the edge of the platform, a pendulum assembly with support nodes is welded. It is important not to overheat the bearings, so these parts are wrapped in wet rags or constantly poured with water to cool.
The pendulum arm assembly with bearing assemblies is welded to the platform at a distance of 50–60 mm from the edge
A console with an installed clamp and a U-shaped angle grinder is welded onto the pendulum lever. The position of the angle grinder is chosen based on personal preferences. There are different opinions on how to fasten the grinder ("on your own" or "on yourself"). Professional locksmiths work with the tool, orienting the sheaf of sparks towards themselves, arguing that if the grinder falls out of their hands for any reason, the tool will fly off in the opposite direction. Hobbyists most often work with medium or small grinders, so they prefer to have the disc rotate "from itself", as this allows control of the cut and prevents damage to clothing. When fixing the tool, do not forget to place the protective cover correctly - it should protect the worker in the event of a disc rupture.
An angle grinder is attached to the assembled machine. Focusing on the weight of the tool, select and install the return spring. To do this, loops are welded to the frame and the pendulum or holes are drilled with a diameter of up to 5 mm.
In order not to damage the plastic body of the grinder, strips of rubber are laid between it and the brackets
Perform a trial run grinder. First, check the operation of the machine in idle mode. At the same time, attention is paid to vibrations and backlashes of the working parts of the equipment, which, if necessary, are eliminated.
Using a cutting wheel of maximum thickness, a groove is cut in the machine platform for the cutting disc. If necessary, the grinder is removed and the slot is expanded to the desired size.
It looks like an improved emphasis with a clamping device

At the last stage, stops for blanks are attached to the platform. Most often, two strips are provided (for cutting at an angle of 45 and 90 degrees), fixing them with a welded or threaded connection.

Often, fixtures for holding the workpiece are equipped with a measuring tool. By fixing a metal ruler on the stop bar with a reference point from the grinder disk, you can quickly and accurately cut off the part of the required length. Also, if desired, you can install protractors, vices and clamps of various designs. Such additional details allow you to make, for example, a full cut or groove in the workpiece at any angle, free your hands, and so on.

Do not forget to paint the fixture after all finishing activities have been carried out. Even a thin layer of enamel will protect the equipment from rust and make its appearance more aesthetic.

Safety

In the process of working on a cutting machine (as well as during its operation in the future), safety precautions should be strictly observed. Be sure to use a protective mask or goggles, and position the angle grinder so that the sheaf of sparks is directed away from you. The high fire hazard of the equipment requires work in a ventilated area and away from fuels and lubricants. During welding activities, a protective mask, thick leather gloves, closed shoes and protective overalls should also be used.

When working with a cut-off machine, do not try to speed up the process by applying excessive pressure to the tool. At best, such a rush can result in a torn disc and a jammed clamp nut.

When using a welding machine, ensure good grounding and avoid operating the equipment with exposed cable sections. Remember that outdoor welding in rainy weather is prohibited. As for the operation of the cutting machine, when arranging a button to turn it on, protect yourself by installing a simple decoupling with a 12-volt power relay. To do this, you can make a pedal with any non-latching switch (for example, a doorbell button) and use any solid-state relay rated for switching currents of at least 10A. A battery or accumulator with a voltage of 5 to 24 V is used as a power source.

A cutting machine from a grinder is a handy tool that can be easily made if you have the skills to work with electric welding and metalwork tools. A pendulum circular saw made in just one day will save time in the future and allow you to perform plumbing and welding work accurately and accurately.

An angle grinder (grinder) is a universal power tool with which abrasive processing of metal, wood, stone and other materials is performed. The turbine is used for cutting and cleaning small parts or workpieces. In this case, you often have to hold the tool in your hands for a long time, which greatly complicates the quality of work. To reduce the load on the hands and increase safety, a special device was created that can be bought ready-made or built independently from improvised materials.

The purpose of the frame for the grinder

The use of a bed allows you to cut products quickly and efficiently

Mounting a power tool on a rigid stand has a number of advantages. So, thanks to the bed, you do not have to hold the grinder in your hands, which will allow you to focus on the accuracy of processing the product. In addition, you will eliminate the risk that the impeller may slip out of your hands due to fatigue or carelessness. Grinders often have special threaded holes for fixing on the frame, thanks to which you can position the tool at a convenient angle. And the rotating holder allows you to change the vertical position of the tool, depending on the tasks.

Tools and materials

As a rule, at home, a grinder stand is made of profiled metal pipes, as they are very durable and reliable. Although some craftsmen make holders from lumber. In this case, it is desirable to use only the hardest wood species that are able to withstand heavy loads and not deform during operation. As for metal structures, here the problem lies only in the need to use electric welding and the ability to work with it. However, if you think a little, then most of the welding work can be replaced by drilling, that is, using bolted connections. In addition, this option will allow you to almost completely disassemble the machine.

To work, you will need the following materials and tools:

welding machine;
perforator;
grinder;
metal corner;
profiled pipes and channel;
powerful spring;
relay 12 volts;
bolts, nuts and a set of keys;
shield made of chipboard or metal (work surface).

Safety

As you understand, when making a metal bed, you will have to work with welding. But before you pick up this device, you must definitely familiarize yourself with the safety precautions. The welder is dealing with electric current, so improper handling of the equipment can lead to irreparable consequences.

Before connecting the device to the network, you need to inspect it. Make sure that the cable insulation is not damaged. If the condition of the wires has alerted you, then do not use this welding until you replace them.

The connecting parts of the cables must be made of brass or bronze. These metals have excellent thermal conductivity, so the cables in this case do not heat up.

After an external examination, turn on the device by pressing the "on" button. At startup, only the sound of the running cooler should be heard. This suggests that forced cooling has started working along with the device. When working with welding, you need to remember the high temperature - the applied seams are very hot, so all manipulations with metals must be performed in overalls. Use special gloves, a mask and boots with rubber soles. The latter should in no case be forged.

Wear a respirator if working in a poorly ventilated area.

Preparatory stage: drawing

Frame dimensions are selected depending on the dimensions of the grinder

One of the key points in assembling a metal frame for a grinder is the development of a competent drawing. This will make the device as convenient as possible for operation, as well as avoid damage to expensive material.

First of all, you need to study the finished model of the bed. To do this, visit any hardware store and look at the designs that the industry has to offer. So you can understand how to make such a device correctly. As for drawing up a drawing, there is no need to have special skills. It is enough just to correctly and accurately measure the finished product and transfer them to a sheet of paper. After that, you can start assembling the bed.

Each turbine needs its own drawing, since fixtures from different manufacturers can vary greatly in design. Perhaps a small adjustment will be enough, or maybe you will have to create a sketch from scratch.

Instructions for making a bed for a grinder with your own hands

At home, the easiest way to make a design of two frames and a holder

The simplest frame for a grinder consists of two frames and a holder. The order of work is as follows:

We cut profiled pipes and drill holes in them according to the drawing.
Using welding, we make the lower and upper frames of the future design.
We cut out a working platform from a sheet of iron or chipboard. If the impeller is powerful, then it is better to use metal.
We fix the lower frame on the platform and weld the upper frame to it.
We attach the holder to the vertical frame with bolts. It should rotate freely, like a pendulum.
Install the spring. It is needed to return the tool to its original position. One end of the spring is attached to the upper end of the vertical frame, and the other to the holder.
For the convenience of working with the device, install a button with switching through a relay, through which power will be supplied to the tool.
Give the structure a finished look by covering it with paint.
At the end, equip the bed with a movable ruler with a limiter. This will allow you to cut products as accurately as possible.

After assembling the fixture, install a grinder in it and check the operation of the tool at idle. If the circle does not touch anything and rotates freely, then the design can be used for its intended purpose.
The holder for the turbine can be equipped with a shock absorber. This will allow the cutting tool to move around the work platform.

An angle grinder is a very useful tool. With this simple design, we free our hands and achieve the most even cut without the use of a vise. Such a device can replace a cutting saw, while the angle grinder can be returned to a mobile state at any time.

Every self-respecting master has at his disposal such a type of tool as an angle grinder or grinder. Everyone knows about the range of possibilities of this tool. Many are tempted to make a cutting machine from a grinder with their own hands, which is quite real. You can show ingenuity and imagination to make a home-made machine, but it is better to use proven schemes offered by experienced specialists.

Why make a machine from angle grinders

A cutting machine is a useful and necessary thing, and not only in industrial conditions, but also in the economy. With this useful tool, you can accurately cut parts and workpieces. This is achieved due to the reliable fixation of the cutting disc, in the spindle of which you can install not only abrasive wheels for cutting metal. The stationary machine can be used for cutting tiles, bricks, marble, granite and other similar materials, while using special diamond-coated wheels in the design of the tool. If necessary, such a machine can be used for sawing beams, boards and other wood blanks.

Many people who have repeatedly faced the need to make an accurate cut of the workpiece want to know how to make a cutting machine from a grinder and improvised materials. Holding the grinder in your hands, you can also make an accurate cut, but it is more difficult to do this, since the tool has to be held exclusively with two hands. With the help of a home-made cutting machine, you can not only perform, but also simplify the following work:

Cut sheet material, such as galvanizing used for chimney insulation and other purposes
Cutting ceramic tiles and tiles - keep in mind that the cut can only be made straight
Cutting materials at different angles
Sawing metal profile, pipe, wooden beams, boards, etc.

To manufacture a machine from a grinder, an appropriate approach is needed. After all, the tool itself is very dangerous, so the slightest miscalculation can lead to the fact that the master will be seriously injured. The consequences of working as an angle grinder in case of non-compliance with TB are known, therefore, at the beginning, before building a homemade product, it is worth noting the following:

Only with the correct manufacture of a stationary cutting machine, you can be sure of its reliability and safety.
If you planned to do it, then you need to calculate each step so that trouble does not happen during operation
Using the machine is in some way safer than working with the tool while holding it in your hands. However, it is necessary to be aware that the grinder is a mobile tool, and making a homemade product is already a safety violation.
For manufacturing, it is necessary to use materials of appropriate reliability, corresponding to the power and dimensions of the main power tool

Having dealt with the need to manufacture a machine, you can get down to business.

This is interesting! If you can’t decide which is better - to buy a new machine or to make it yourself, then the second option is more preferable, since the cost of a factory device will cost at least 10,000 rubles. With self-production, no expenses will be needed, since the grinder is already on the farm, and composite materials can be found in the garage.

Making a homemade machine from a grinder

Making your own machine from a grinder is not difficult on your own. Moreover, there is a lot of variety of manufacturing options, which depends on the available materials at hand and imagination. There are two types of cutting stationary machines from the grinder:

Simple - it received such a name for one reason, which is not only the ease of manufacture, but also the minimalism of the device itself. The tool is attached to the workbench with additional materials, and it can be operated
Complicated - it is rational to manufacture such machines if you plan to use it often for different actions. In most cases, a simple device is enough for a home garage, the manufacture of which takes a little time, effort and consumables.

In order to make a cutting machine from a grinder with your own hands, you will need consumables, which are metal plates, as well as profiles and fasteners - bolts, nuts and washers. From a specialized tool, you only need an electric drill and a welding machine. In more detail about how to make the simplest version of a cutting machine from a grinder, we will consider below.

Option 1 - an easy way to make a cutting machine out of an angle grinder

A simple way to make a homemade product involves making a base on which fixed connectors for a movable plate are attached. So, in more detail about how to make a machine from an angle grinder:

For convenience, a handle can be welded to the movable bar, and an auto-return spring can be installed, which will return the tool to its original position, that is, move it up. The photo below shows a finished installation for cutting from a grinder. As can be seen from the example, its manufacture will require a minimum of effort and materials, and as a result, a stationary device for cutting different materials is obtained.

When constructing the device, do not forget that safe operation depends on how to fix the grinder. It must be securely fixed at 2-3 points, which will exclude its movement during work, as well as “flying off” from the movable bed. When installing the tool on a movable frame, it is necessary that the position of the angle grinder be strictly at a right angle, that is, the circle must be located strictly in a vertical position.

The resulting device is suitable for processing various materials from wood to durable stone. When working with a tool, do not forget to use safety glasses, gloves, and overalls. Instead of a workbench, you can use a wooden or steel frame on which to implement the idea.

This is interesting! Similar simplest beds for angle grinders are manufactured at the factory, so if you have an extra 2-3 thousand rubles, you can purchase a ready-made base and use it right today. However, there are no difficulties in self-manufacturing, therefore it is necessary to decide in each individual case on your own which is better.

Option 2 - how to make a pendulum saw easily and quickly

With a welding machine and consumables, you can make a stationary grinder machine in a matter of hours. And for this you don’t need to buy anything, since the necessary tubes, fittings and profiles can be found in a garage or a pile of scrap metal. To build the simplest cutting machine, using angle grinders as the main tool, you will need to use the following details:

Metal profiles 150-200 mm
Sleeve length 10-15 cm
Hairpin 20 cm long and 8-10 mm in diameter
washers
Metal corner
Sheet of metal 2-3 mm thick, which will act as a base

So, to make a simple homemade product, you will need to perform the following steps:

Cut the stud to the required length, then place the sleeve inside (it should move freely along the stud), and tighten the nuts onto the ends of the protruding stud. Tighten two nuts on both sides, as the second will play the role of a lock nut
The nuts must not be screwed in completely, they must not come into contact with the sleeve
The resulting structure should be welded to the steel sheet. At the same time, it is important to grab the nuts, and the sleeve must remain movable, that is, move freely
At the next stage, it is necessary to make fasteners for the grinder. To do this, you need metal profiles, as well as washers that will play the role of brackets
Cut to the required length (it all depends on the tool used, but for a low-power grinder, the profile length is 15-20 cm). Weld washers to the ends of the profiles. It is recommended to use at least 2 mounts for the grinder, but three is better
The angle grinder has threaded holes for connecting the handle. We use these holes to attach the tool to the movable base using pre-prepared brackets.
First, the brackets are attached to the tool using bolted connections of the appropriate size, and then the reverse ends of the profiles are welded to the sleeve. As a result, we get a finished machine, which can be made literally within an hour

The photo below shows the design of a home-made grinder machine with a detailed description of the necessary materials. Using the instructions, and for someone, a diagram is enough to make a home-made cutting machine. At the same time, it is important to take into account that the casing for the angle grinder must be mandatory, otherwise the risk of serious injury increases. It is strictly forbidden to operate the tool without protective clothing not only on a person, but also on the device itself.

The simplest device is ready for operation. The angle in the design of the machine is used as a guide for centering cutting materials. It is also necessary to make a straight hole in the iron sheet, where a part of the disk will “enter” when sawing blanks.

Option 3 - an even easier way to make a cutting machine from an angle grinder

Many do not have welding machines or do not know how to use them, so if you belong to the category of these people, then you should not despair. You also do not need to ask your friends and neighbors to make a machine. It is quite possible to do without welding, and bolts with nuts will be used as the main connectors. So, to design the simplest cutting machine from a grinder, you will need the following consumables:

Corners - and a small number of them up to 1 meter. If there are pieces, then it's even better. The thickness of the corners is standard 2-3 mm
Steel tube 30 cm long - will be used as a handle on which the grinder will be attached
Steel sheet 2-3 mm thick and of any size, but not less than 20x20 cm
Bolts with nuts with a diameter of 8-10 mm

Let's start making a homemade tool. The manufacturing process is as follows:

First you need to attach a 15 cm long corner to the steel sheet
Attach another corner perpendicularly to the wall of the lying corner, using bolts and nuts for this. If there is welding, you can make tack welds
Attach the tube to the perpendicularly installed corner using all the same bolted connections
The tube should move freely, so it is not necessary to tighten the nut on the bolt. Instead, it is necessary to lock the fixing bolt with another nut.
Connect two steel plates measuring 5x6 cm to the tube at a distance from the junction. These plates will attach the grinder to the handle
Attach the angle grinder to the casing with pre-prepared steel plates

As a result, we get the simplest cutting machine, the photo of which can be seen below.

There are many manufacturing options for similar designs, so it all depends on what you want to end up with and what consumables are available. It is not very convenient to work with the version of the cutting machine discussed above, since it is necessary to constantly hold the tool (due to the lack of a return mechanism), but this is easy to fix. A spring must be attached to the protruding part of the tube, which will return the tool to its original position, eliminating the need for the master to hold the running unit.

How to make a start button for a pendulum machine from an angle grinder

The angle grinder works at the push of a button. Moreover, the speed of rotation of the spindle depends directly on the pressing force of the button. This means that an adjustment mechanism is built into the button, the operation of which facilitates the operation of the tool. When operating an angle grinder on a stationary machine, it is necessary to think over the starting system so that you do not have to hold the handle with one hand and press the button with the other.

If the tool is equipped with a conventional button, which is automatically fixed when it is turned on, as, for example, in the first version of the construction of the machine, then there are no difficulties. First, the tool is turned on, and then work can be done. However, most angle grinders are equipped with self-shutoff buttons that must be held by hand during operation. There are two ways out of this situation:

Use ties (for example, plastic) or clamps of the appropriate diameter. They hold the button in the pressed position. At the same time, it is also necessary to take into account the latch, which is responsible for the self-switching of the tool. Both the latch and the button must be pulled together with a clamp, screed or other similar materials. In this case, the principle of operation of the device will be as follows - if you need to start the tool, you need to plug the plug into a socket or make a switch
It is rational to remake the starting system if the tool is planned to be used more often as a cutting machine than an autonomous grinder. To do this, it is necessary to bring the wires from the angle grinder to a separate switch, which will turn the tool on and off if necessary.

The power button, if it is displayed, is best located on the handle. A home-made machine does not require large expenditures for its manufacture, which, in fact, is its main advantage.

Important points in the construction of a pendulum machine

The type of tool in question belongs to the category of dangerous ones, therefore, when constructing equipment, the following main points are taken into account:

The manufacture of the frame is the basis responsible for the reliability of the installation. It is impossible to save on the manufacture of the frame, therefore only steel materials are used, the thickness of which is at least 2 mm
Frame - the design of this part may be different, but the most important thing is to ensure the mobility of the cutting tool. This is achieved through the use of different materials, but in any case, it is necessary to think over the quality of the swivel joint well, since your life depends on it. It is better to spend more material, but make a quality and safe cutting machine
Tool mount - angle grinder is fixed directly on the moving part. Moreover, the fixation should be as reliable and of high quality as possible. When working with an angle grinder, “backstrokes” can occur, which are dangerous because the machine can simply be damaged, and the master who performs the manipulations will suffer from this
Providing for the arrangement of a counterweight is a small but important element that allows the tool to return to its original position as unnecessary. This will eliminate the possibility of damage to parts of the human body.
Protective cover - it must be mandatory, and it does not matter what design of the machine is invented, but it is strictly contraindicated to use the device without a protective cover on
The presence of a ruler - this will improve the accuracy of the work performed, which is important when cutting parts such as tiles, ceramics, and metal
The starting device is also a kind of device that affects safety. The control button must be in close proximity to the master performing the work. This will allow you to quickly respond at the right time by turning off the power supply to the tool.

In addition to options when the machine has a movable part, there are also ways to make cutting devices with the tool located at the bottom of the bed or workbench table top. However, this option is only suitable for cases where it is planned to saw wood. Below is an example of how to make a home sawmill quickly and easily from a grinder. Details on the manufacture of home sawmills can be read

Having a stationary machine in the garage, you can quickly, and most importantly, cut different materials with high quality.
Obtaining a high-quality and even cut, which makes the device perfect
Cheapness - if there is a grinder, then the cost of manufacturing the machine will be minimal

Now let's find out what are the disadvantages of the home-made device in question:

Low reliability - even with the most competent approach, it is not excluded that a person can get various injuries just because of working on such home-made equipment. To protect yourself, you need to work in protective clothing
The complexity of transporting the device - it all depends on its size and weight. Only if the machine is called stationary, then it is intended for operation in only one place

If you already managed to manufacture the type of equipment in question, then it will not be difficult to figure out the correct operation of it. Already at the first test of the tool, you can feel how effective its work is. Below is a selection of photos showing options for homemade cutting machines from grinders. In addition, such a tool as angle grinder is fraught with many more interesting ideas for expanding functionality, but that's a completely different story.
