Homemade drilling machine from a drill with your own hands. Homemade drilling machine and other accessories from a drill Homemade desktop drilling machine with your own hands

The electric drill is universal tool, since not only drills and cutters can be clamped into its chuck, but also wooden details, in case the machine is used in a lathe. The need for a drilling machine arises when the home master needs to drill holes at right angles. In this case, the master faces a choice: buy a ready-made drilling stand or make a machine from a drill with his own hands. We will show you how to implement the second option.

In the manufacture of a stand for fixing a drill, it is necessary to understand the principle of its operation, and show imagination in the manufacture of its individual components.

Rack Option #1

For example, the following is an instruction for making a drill fixture from simple improvised materials.

Rack Option #2

The figure below shows another homemade drilling machine, the stand for which can be made of thick plywood, and the rest of the parts - from a wooden bar.

The role of the guide in a drilling machine made from a drill is played by aluminum profile. But, if you do not find such a profile, then you can replace it with furniture guides(telescopic).

Rack Option #3

If you have a house lying around soviet era photo enlarger, then it can serve as the basis for a stand for a drill. This design already has rigid guides, as well as a gear mechanism that provides vertical movement of the carriage along them.

You only need to modify the design a little by attaching clamps to the carriage, and comfortable handles to the height adjuster.

Well, if you don’t have the desire to design devices for a drill with your own hands, or you just don’t have time for it, but you still need to drill a hole with a drill strictly at a right angle, then you can buy a ready-made stand at a price of about 1200 rubles.

Other options for drill machines

The drilling machine can serve as an engine for constructing various woodworking tools. Consider what else you can make a machine from a drill with your own hands.

Frazier

To make a router with a drill, you will need to take a regular clamp used for water pipes.

You will also need to find some chipboard (you can use a slab of old furniture), and then assemble such a structure as in the figure below.

This kind of router can be used, for example, for milling a groove in the end of a tabletop, for stuffing a T-shaped profile, or for shaped milling of the ends of wooden parts. Of course, good quality milling in this way is difficult to achieve, since the device does not have enough speed. For comparison: the spindle of a router can rotate at a speed of 26,000 rpm. and more, thanks to which a high quality surface finish is achieved.

You can also make a milling machine out of a drill, if you clamp it in this way, as shown in the figure below. In this way, a quarter is selected in a bar for inserting glass, for example, in the manufacture of a window leaf.

For turning small, round parts, you can make a device in which the drill will give rotational movement to the workpiece. by the most in a simple way to perform turning work on wood can be called the one indicated in the figure below.

Such a wood lathe can be made in minutes. To make it you will need wooden beam or a board, a couple of corners, as well as a sharpened bolt.

More "advanced" drawing lathe, which can be made from a drill with your own hands, is presented below.

If you do not have the opportunity to make such a device from metal, as shown in the drawing, then you can do a pair of clamps attached to a workbench.

The first clamp with a clamp can be used to secure the machine to the workbench.

As a clamp for a drill, you can use a small vice with a clamp clamped in them. With the second clamp, you need to clamp the homemade tailstock with a screw screwed into it to center and maintain the part. The end of the screw must be tapered.

As a handpiece, a bar of the required thickness is pressed against the workbench.

It is also not difficult to design a homemade lathe from wooden blocks as shown in the following figure.

For precision turning work with long and large parts, it is recommended to make a lathe from a metal profile(square).

In the manufacture of this design, it is necessary to accurately maintain the alignment of the headstock and tailstock. The unit to the headstock can be secured with a pair of clamps.

The tailstock must be movable in order to be able to process parts of various lengths.

The tool rest must also be movable and move both along the bed and across it so that you can move it closer to the workpiece to reduce the leverage. If the lever is large, the tool may be pulled out of the hands, and the part out of the chuck, which is fraught with serious injury.

It is important that the support platform rotates, for example, when machining a part at an angle.

If you make such a machine, then it can easily be converted into a universal one. It is enough to clamp an emery or felt wheel in the cartridge of the apparatus, and the design turns into grinding machine from a drill. In the same way, you can make a grinding unit out of it.

A simpler model universal machine easy to make from a regular planed board. To do this, you need to cut it into parts, and assemble the structure, as shown in the figure.

This is what the bed looks like when the table is removed.

The thickness of the board used in the construction is 2 cm. The length of the product is 50 cm. The width of the fixture is 20 cm.

The height of the racks is 9 and 14 cm. The height can be different and depends on what diameter the grinding wheel will be used. The whole structure is twisted with self-tapping screws. It is recommended to smear the joints of parts with glue before assembly.

On top of the racks, 2 clamps are fixed, one of which is cut and unbent. As a soft pad used cut polyethylene tube, nailed with carnations.

On the frame, it is necessary to make a small cut (groove) and expand it from the bottom side so that the head of the coupling bolt does not interfere.

Next, you should twist 2 boards measuring 20 X 27 cm with a bar between them, the thickness of which is 4 cm (this way you get a table). The bar is needed so that the hand can freely pass between the planes while screwing the table to the frame.

A groove is also cut in one plank to secure the table to the base. After that, the table can be attached using a screw with a washer.

Thanks to the grooves, the table can be moved to the required distance to the cartridge. If the table is rotated, it will be possible to move it across the machine. The length of the groove determines the distance that the table can be moved.

After fixing the drilling machine, you will get a universal fixture.

Now, if you clamp the drill chuck grinding wheel- You will receive a grinding unit. The presence of a reverse in the unit during grinding is desirable, but not necessary.

If set abrasive disc(for metal) from a grinder, then it becomes possible to cut metal rods. When cutting metal, be sure to wear safety goggles. You can also install a gear cutter, and cut thin plastic with it.

When installing abrasive wheel- it turns out a sharpener.

Such a unit can be used for turning knives, drills, planer knives, and also for sharpening tools for a wood lathe.

If you fix the guides on the table, and install the drill in the chuck, you get a filler machine.

Thus, the drill, thanks to the clamping chuck, is the basis for creating machines for various purposes. Such an increase in the functionality of a conventional drill will be very useful for a home craftsman who has various technological operations at his disposal.

It does not always make sense and expediency to buy a factory-made drilling machine. You can make a vertical drilling machine from a drill with your own hands. To do this, you need a drill and materials for making a stand. Such equipment is recommended for use in home workshops or garages, when drilling is not the main operation or is performed quite rarely and the accuracy of the hole can be neglected.

To speed up the process, just buy a specialized drill stand in the tool store. The result is a semblance of a household-level vertical drilling machine, which is not inferior in drilling accuracy to machines for home workshops.

The photo shows drilling stands factory production. They can be purchased at any online tool store for prices starting at $200.

The article is intended to give you ideas on how to make a drilling machine from a drill yourself, so we do not give a clear algorithm for its manufacture, because it is made from improvised materials: some masters will have it, others will not. Therefore, we give the main ideas, and everyone will apply their own constructive solutions and make his own vertical homemade drilling machine.

If you are not looking for easy ways, then we will make a homemade rack. The rack can be made of wood or metal. Wood will be cheaper, easier to manufacture, but durability will suffer.

Metal ones are more complex, but they have an incomparably longer resource and strength characteristics. The choice of rack material also depends on the workpieces being processed: with constant drilling of metal, it is better to make metal.

Machine assembly

Metal racks are assembled from the corners for the carriage, square pipe 50x50 for the stand and 10x10 for the drill arm, strips for the base and lugs. The base and bracket are welded, after which all elements are assembled and bolted together. It is recommended to manufacture several brackets with different adapters (clamping rings) under different types drills. The carriage moves along the bar with the help of a steel cable wound around the handle drum. So that the carriage does not have play and does not fall down under its own weight, it is drilled, threaded and a bolt (or several bolts) is tightened. This selects the backlash between the carriage and the stand of the future drilling machine. The handle for moving the carriage is made from rolled products with a diameter of 6 - 8 mm.

By having several brackets with different clamping rings, it is possible to flexibly select drills and process almost any material.

In future homemade equipment can be upgraded and modified, for example, mark or install a scale that will indicate the length of the carriage movement. This helps when drilling blind holes.

There are several mounting methods:

• several clamps;
• on a metal bracket in the hole for the neck of the drill.

The easiest option for making a homemade drilling structure at home

A homemade drilling machine from a drill will never replace a factory one and will always be inferior in build quality and drilling accuracy. The main advantage of homemade - low price, the ability to drill holes when the factory machine is not available for one reason or another.

On the farm, the home master should have a set of all tools, and therefore this is the unit that will help him further expand his functionality.

Many for drilling various holes in everyday life they can be satisfied with an ordinary drill, however, the possibilities and tasks of even the simplest drilling equipment are more global.

A desktop drilling machine, in addition to reaming, countersinking and reaming, can also mill (there is a milling unit), as well as grind various surfaces and perform a number of other tasks.

Such equipment is especially relevant for radio amateurs, who, with the help of it, can solve a number of their narrowly focused tasks.

Such a unit for a home workshop can be bought at any specialized store, but it costs a lot, and not every master will find extra money to purchase a professional drilling machine, which is shown in the photo below.

Meanwhile, if you wish, you can assemble a home-made drilling machine for drilling wood and metal with your own hands from an ordinary drill.

Of course, you will have to spend personal time on the manufacture of the machine, but the result is worth it.

Desktop homemade drilling machine in a mini version for wood and metal, with all necessary materials, everyone can do home master.

Drilling the most different holes in everyday life it is carried out, as a rule, with the help of a hand drill, which is in the home workshop of every skilled owner.

Meanwhile, even at home it is not always possible to achieve the desired result through the use of an ordinary drill.

In this case, the question arises of making a mini vertical-horizontal drilling machine for wood and metal with your own hands.

Such a universal unit is simply necessary for those who are engaged in electronics for drilling small holes in printed circuit boards, which cannot be done with a hand drill.

In addition, a home-made drilling machine will not interfere and, if necessary, drill through and blind holes in various types materials.

With it, it is very easy to perform reaming and countersinking, as well as, if necessary, to cut the thread.

If you additionally install a milling unit on it, then the capabilities of the unit will expand even more.

The milling unit will make it possible to perform a variety of simple operations for vertical-horizontal milling of a variety of materials.

A filler mini drilling unit for drilling printed circuit boards can be made from the most ordinary drill, however, to solve more complex tasks, a more structurally complex device, the same milling unit, will be required.

Any professional drilling unit consists of several required elements, which include such as a drill, countersink, tap, as well as a reamer.

Do-it-yourself filler mini machine must also contain all these components.

If the drilling machine is assembled according to all the rules with his own hands, then the home master can easily, using a milling unit, in addition to drilling printed circuit boards, cut and bore a hole with the required diameter, grind it precisely, and also perform a number of other specific tasks.

Before proceeding with the assembly of the unit, it is recommended to carefully study existing types drilling machines and understand the basic principle of its operation.

The video posted above shows homemade unit for drilling in operation, which can also be used for drilling printed circuit boards.

Species and types

Currently on industrial enterprises and in everyday life a huge number of various modifications of drilling equipment are used.

Many of them are intended for solving exclusively professional tasks, and for home use they just don't fit for a variety of reasons.

In the photo below, you can see an industrial drilling machine.

Today you can find spindle machines, semi-automatic machines, vertical drilling, as well as many other types of units.

For domestic use, a filler mini unit is suitable, capable of solving simple tasks.

For example, if the machine is needed mainly for drilling printed circuit boards, then it can be assembled from the most ordinary drill.

Like any other equipment, drilling industrial units have their own special designations and markings, which can be used to determine their type and main purpose.

The most popular devices that are most often encountered are spindle devices, as well as units for radial and horizontal drilling.

Very popular coordinate unit designed for boring workpieces.

All drilling equipment can be safely attributed to the universal type. For a home workshop, it will not be difficult to make a universal-type filler mini-unit with your own hands.

If desired, a home-made coordinate unit can be automated as much as possible and supplemented with various devices, which will only add to its overall functionality.

Depending on the functional purpose each drilling machine, including the coordinate one, consists of a certain number of elements.

Any unit of this type, including a home-made one, necessarily consists of a bed, a steering rack, and an engine. The photo below shows a homemade filler mini drilling unit.

Design features

The drilling machine is a type of industrial equipment designed to solve narrowly focused tasks.

It must necessarily include a transmission mechanism, control and working bodies, as well as a sufficiently powerful electric motor.

Each mechanism included in this equipment has its own purpose, which determines its functional tasks.

So, the transmission mechanism is intended mainly to transfer the necessary movement to the working bodies, directly from the installed engine.

In this case, the working body is a drill, which is attached to a chuck, which in turn is connected to a spindle and a rotating shaft.

In the machine of this type, the rotation from the engine to the working bodies is transmitted by means of a belt drive. In order for the drill to be in a given position, a rack and pinion gear is used, associated with a special handle.

It is imperative that such a machine, even if it is assembled from a drill, must have buttons in an accessible place that are responsible for turning it on and off.

Machines of this type have a fairly simple device, moreover, they can perform a huge number of very different functions and solve many narrowly focused tasks.

Assembling such a machine with your own hands, for more high precision performing work directly on its moving part, it is recommended to place a special scale.

It will help control the depth of blind holes. It is also best to make such a machine on which it will be possible to change the rotation speed of the cartridge, depending on the tasks performed.

The desktop should be made exclusively from a solid metal plate, rigidly fixed to the base.

The video below shows a homemade drilling unit, with which you can drill printed circuit boards and more.

Principle of operation

A drilling machine assembled according to all the rules will be able to successfully drill holes of various diameters, including micro ones, with great accuracy, which is especially important for printed circuit boards.

Despite the apparent simplicity, you need to work on it in compliance with generally accepted rules.

So, just before you start work, you need to check the availability of power in the network, the integrity of all equipment, and also clear the desktop of everything superfluous.

There must be a vise on the table itself, with which it will be possible to conveniently fix the workpiece.

Before starting work on the part, it is necessary to mark the future hole in accordance with the drawing, then place it in a vise on the table and firmly clamp it.

Next, a drill is fixed in the chuck and a test run is made. Homemade vise for the drilling machine, which are used during work, must have certain dimensions, including in order to work with micro holes.

During the test start of the machine, it is necessary to check the rotation of the drill and make sure that it rotates without describing the circle.

This is especially true when drilling micro holes. At the time of drilling, the handle should be actuated with smooth movements, while the drill must be periodically cooled.

Drilling micro holes should be done with extreme precision, for which use coordinate indicators.

Upon completion of the work, the drilling machine should be turned off, open the vise and remove the finished workpiece. The video above shows how the machine works.

How to assemble?

The easiest option to assemble a filler drilling machine without a steering rack is to use an ordinary drill.

In this case, it is necessary to make the table massive in order to minimize the vibration of the machine during operation. A stand for a drill can be made from both chipboard and metal corners.

First you need to connect the stand and the table to each other at a right angle, while the drill should be fixed with clamps. A driving mechanism should also be provided.

A vise must be attached directly to the table, in addition, the on and off button must be in a visible place. In the video below you can see the manufacture of a machine from a drill without a steering rack.

You can assemble a more complex and functional machine with a steering rack for drilling from the engine from the washing machine. This device allows, among other things, to drill micro holes with great accuracy.

In this case, the desktop should be even more massive, since the vibration during operation will be quite strong.

Particular attention should be paid to the moving part of the unit, and for these purposes it is better to use ready-made drawings. It is recommended to connect the engine with the cartridge using a belt drive.

If all actions are performed correctly, then such a machine will be able to drill even micro holes with great accuracy.

The video below shows a homemade machine powered by an engine. washing machine which will be very useful in your workshop.

For a skilled person, nothing is impossible. And if desired, a talented enthusiast is able to make anything. Today we will talk about how to assemble a drilling machine with our own hands, since this topic is more than relevant.

Buying a factory model, even if we are talking about used equipment, requires considerable expenses for the family budget. We will tell you how to assemble a metal drilling machine from improvised means with minimal investment.

To date, there are 2 proven designs that are easy to assemble in "garage" conditions.

This is a machine tool based on an electric drill and a unit based on a conventional asynchronous motor from a household appliance. Let's consider each of the options in turn.

We will take an ordinary electric drill as the basis of our future machine.

This tool is lightweight. This suggests that we do not have to use structures made of durable metals as a stand. Ordinary wooden planks or even chipboard is quite suitable for our purposes.

A home-made drilling machine for metal based on a drill consists of four main components, such as a bed, vertical post, electric drill and feed mechanism. The choice of the base of the machine (bed) is a very crucial moment, since the intensity of vibrations during operation will depend on the strength and massiveness of this design.

This is very important, since a massive bed will improve the quality of workpiece processing.

What can be adapted as a base for the machine? If you have a Soviet enlarger at home that was used to develop photographs, you are in luck.

After some manipulations, it is easy to turn it into a full-fledged basis for a homemade drilling machine. If you could not find a photographic enlarger even on the used equipment market, you can replace this element with an ordinary design from a 20 mm furniture plate. It will provide sufficient rigidity for precise work.

In the process of fixing the bed on the rack, it is very important that a perfectly right angle be maintained between them.

This will increase the accuracy of drilling.

It is necessary to fix two guides on the rack, which can be made from ordinary metal strips. The block with the drill fixed on it by means of clamps will move along the guides. For additional vibration isolation of the tool, it makes sense to put a rubber gasket between the electric drill and the shoe.

The vertical movement of the block must be carried out using a lever.

In order not to experience discomfort during drilling, it makes sense to equip the feed mechanism with a spring capable of returning the tool to its original position.

The spring must be fixed on the block on one side, and on the fixed beam on the other.

If you do not plan to use an electric drill autonomously, you can take care of the ergonomics of your homemade metal drilling machine. To do this, disassemble the drill switch and install the start button in a place convenient for you.

That, in fact, is all.

If you follow the above algorithm, assembling a drilling machine with your own hands will not be a problem for you.

Homemade machine based on an asynchronous motor

If you search carefully, in the household you will most likely find a variety of electric motors from household appliances. The best choice for a metal drilling machine - an asynchronous motor, which is used in drum washing machines.

Be prepared for the fact that the assembly of such a machine will be somewhat more difficult.

First of all, you will need a more massive rack that will absorb significant vibrations from the washing machine motor. To minimize them, you need to install the motor closer to the rack and provide a reliable frame.

But keep in mind that the close location of the motor relative to the rack complicates the design, since it will be necessary to mount the pulley with the transmission. When assembling such a unit, adjust all parts and assemblies as accurately as possible.

The performance of the machine will directly depend on this.

To assemble the pulleys, we need a gear, a hexagon, a metal ring for clamping, 2 bearings and 2 pipe cuts, one of which is with internal thread. The movable structure is made of a hexagon, a tube, a ring, bearings and a threaded tube where the cartridge will be fixed.

The hexagon acts as a transmission element on which the pulley is put on.

To be sure of the reliability of the connection with the hexagon, it makes sense to make cuts on the ends of the tube on which the ring and bearings are put on.

Make sure that all the details of our construction are fixed as securely as possible in order to avoid destruction due to vibrations.

Now let's start creating the adjustment system of our unit.

DIY desktop drilling machine: diagrams and drawings

To do this, we use a pipe with cuts and a gear, the teeth of which should easily penetrate into the cuts we made. To make them as accurate as possible, first apply plasticine to the pipe and run a gear over it. Please note that the ladder pipe must have a height corresponding to the height of the cartridge. The hexagon axle must be pressed into the pre-slotted pipe.

As you understand, the design described above is not easy to manufacture, and not every master is able to bring such a “project” to the end.

If you are not sure that you have the skills to assemble such a drilling machine, give preference to the first design based on an electric drill.

conclusions

We have given two of the most successful examples of making do-it-yourself drilling machines.

Since the information provided is of a general nature, we recommend that you familiarize yourself with the drawings of such equipment in more detail in order to avoid inaccuracies and various kinds of errors during the manufacture of the unit.

Practice shows that an experienced craftsman can easily cope with an ambitious task, such as creating a metal drilling machine on his own.

It remains only to wish you good luck.

Types of drilling machines and their purpose

Metal drilling

Types of drilling machines and their purpose

Drilling is understood as a method of shaping internal cylindrical surfaces in a solid workpiece material using a drill.

Drilling is the only technological cutting method that allows you to make holes in a continuous layer of workpiece material. Drilling machines also process holes already existing in workpieces in order to obtain a given shape, size and roughness of such holes.

Processing on drilling machines is carried out with a multi-blade cutting tool, which ensures high productivity.

Drilling machines are divided into the following types: vertical drilling; radial drilling; for deep drilling; central and multi-spindle.

In the tool shops of machine-building enterprises, vertical and radial drilling machines, which are universal, are most widely used.

One of the most important specifications drilling machine is the largest conventional drilling diameter, equal to the maximum diameter of the hole that can be drilled on this machine using a standard twist drill, in a solid workpiece of steel with a tensile strength s = = 500-600 MPa.

For vertical drilling machines with a column, this diameter is 18-75 mm, and for bench drilling machines - up to 12 mm.

1, a vertical drilling machine of aggregate layout is shown. A hollow column is installed on its foundation slab.

On its vertical guides manually (handwheel 2) move the table on which the workpiece is installed. The spindle is mounted in the drilling head and is subject to rotational and vertical rectilinear translational motion. The latter is carried out manually (handwheel 5) or automatically.

Installed in the spindle cutting tool. In the drilling head there are drive mechanisms for the rotational and translational movement of the spindle, an electric motor and machine control mechanisms. The drilling head can be manually moved along the vertical guides of the column. The required mutual position of the drilling head and the table is set (taking into account the dimensions of the workpiece) before the start of processing, after which this position is fixed.

Inside the column is a counterweight that balances the drilling head.

Do-it-yourself drilling machine from a drill

1. General form vertical drilling (a) and radial drilling (b) machines

In order to start processing each subsequent hole, the workpiece is reinstalled on the table so that the axis of the tool coincides with the axis of the hole being machined. Therefore, the processing on vertical drilling machines of large-sized heavy workpieces with a large number holes is associated with significant labor and time costs.

In order to avoid these costs for processing heavy and complex workpieces, it is advisable to use radial drilling machines (nominal drilling diameter up to 100 mm), which ensure accurate and fast movement of the tool relative to a stationary workpiece and its installation in the required place.

The radial drilling machine consists of a base plate on which a pedestal with a fixed column is mounted. A sleeve is put on it, which can rotate 360 ​​° relative to the column.

On the sleeve, as on a guide, the sleeve moves (with the help of a special drive) in the vertical direction, along the horizontal guides of which the drilling head moves.

Gearboxes and feeds and a spindle assembly are mounted inside the head, and machine controls are located on the front panel of the head. The spindle can rotate around its own axis and move in the vertical direction. The workpiece is installed on the table 8 or directly on the foundation plate.

Before starting processing, the sleeve, sleeve and drilling head are moved so as to set the tool in the required position relative to the workpiece.

In this position, these nodes are fixed using appropriate mechanisms located in the lower part of the sleeve, above the pedestal and in the drilling head. Then turn on the rotation of the spindle, its vertical feed and produce processing.

How to assemble homemade drilling machines?

In modern production, the use of various machine tools has become so popular that now not a single decent workshop can do without this equipment.

And indeed, the machine allows a person to engage in the performance of such work, which he can independently complete, if he can, then with the use of a huge investment of time.

This applies to the processing of metals, wood and other dense materials, which are quite difficult to use without specialized equipment.

Another big plus of the machines is that their manufacture is not difficult.

Homemade drilling machine from a finished drill

If desired, a person with basic mechanic skills can assemble a homemade drilling machine in a couple of days.

It is about the assembly of home-made drilling machines that will now be discussed in this article.

Features and purpose

Machine tools are widely used in industry.

In fact, it was their invention that became a real revolution in the world of industrialists who wanted to quickly increase the pace of production.

Indeed, the presence of machine tools in production is a real blessing. A high-quality drilling and grooving unit is able to perform work with amazing accuracy, while reducing the requirements for the original skills of a person that uses it in work.

This phenomenon is explained very easily.

Let's imagine that you need to create a metal plate with ten holes on it.

The holes must be different diameters. From the smallest to the largest. The plate at the same time has a thickness of 3-5 mm. That is, for working on metal, you will have to use a fairly powerful drill.

Note that large drills are used by large tools, such drills are usually quite heavy.

It will be difficult for an unprepared person to even hold them in their hands. Not to mention the performance of more or less lengthy work.

Plus, you should understand that filigree accuracy will be required of you, because this part is just part of a larger mechanism.

One small slip, and the whole structure can become completely unusable. This is especially true for machines for drilling printed circuit boards.

When processing boards, the accuracy of their markup is determined by tenths of a millimeter.

If you give a man everything necessary equipment, then even with experience, he will fiddle with the plate for no less than a couple of hours.

When drilling boards, this time cost can double.

And this is the case if you have experience and relevant skills.

If it is not there, then it can literally take a whole day to prepare only one plate.

Homemade machine High Quality assembly

If you use a machine in your work, then the operating time is reduced several times. All the necessary tools are already fixed on it.

The drill is stable and clearly directed.

All that is required of you is to correctly install the plate on coordinate table, start the engine and drill a hole. Then change the position of the part and continue working on the same technology. As you can see, the productivity of production is reaching a qualitatively new level.

Components of the machine

Now let's turn directly to the components of the machine. After all, if you are interested in the question of how to make a drilling machine, then first of all you need to figure out the details that will be used when assembling it.

Fortunately, a homemade drilling machine consists of several basic parts.

Their quality determines the quality of the device itself, but it all depends on many factors.

So, the drilling machine consists of:

• Beds or bases;
• Fixing rails or frames;
• The mechanism for regulating the position of the device;
• Fastenings for the working mechanism;
• An engine or mechanism that directly performs drilling;
• Adapters, collets and other similar materials;
• All kinds of handles, stabilizing legs and other additional details that are used to improve the design of the device.

It is worth noting that it practically does not matter whether you are considering a PCB machine or a standard stationary sample.

Of course, you will use different parts to assemble a homemade drilling machine, however general scheme will remain the same.

The difference will be only in specific details and their dimensions.

Using an old table as a machine bed

For example, a home-made desktop unit for drilling boards for electronics will be mounted on a shallow bed. In most cases, you won't even need a cabinet. It will be enough to take a large heavy rail, which by its weight will be at least half the design of the device.

Also, when designing boards, you will need a much simpler and smaller motor, since board drilling requires more jewelry work, where power is not a priority.

Selection of parts for assembly

First of all, always pay attention to the frame or base.

The base for an impressive machine must be very strong and stable. It is necessary for such purposes to use a table with good supports, special stands, etc. Even a cabinet of the right size and dimensions will do, but it's up to you to decide.

If we are considering a desktop sample, then the table here will act as the first base on which the machine itself is already installed.

Do-it-yourself drilling machines from a drill (drawings, video)

In this case, the bed can be made from a metal plate or something similar.

Interestingly, some craftsmen manage to assemble a table or a frame for a machine tool even from the ancient parts of a photographic enlarger. That is, a wide variety of details can be used in the work.

The main thing is that the table or bed on which the device is attached is extremely stable and does not give vibrations during operation.

You can make a frame for fastening with your own hands.

The same is done with the mount for the working mechanism. Here you can use a metal corner with drilled holes or something similar.

The corner is fixed to the table with screws or welded to the frame. Installed there lifting mechanism. It is made from an old jack, shock-absorbing pipe, sliding rails and other similar mechanisms.

The engine will need to be powerful enough to work, so you will have to go through several options.

Moreover, the table and the base of the machine must withstand its weight without any problems and dampen vibrations during operation.

Benchtop drilling machine with spring dampers

A good asynchronous engine from a washing machine or something like that will do.

You can use the engine from the drill or the drill itself.

Scheme of creating a machine

If we consider only the simplest models of equipment that you can quickly assemble with your own hands. Then the standard scheme for assembling drilling equipment is best suited for these purposes.

However, we note right away that there are two main technologies for its assembly.

The first is simpler, it consists in using a ready-made drill, which is simply screwed to the mounts.

The second is a rather complicated option, and it consists in assembling the machine from a separate engine, collets, guides, etc.

1. We collect the table and the base for the machine, we are engaged in fixing the bed.
2. We mount the main stabilizing frame.
3. We connect the mount for the engine.
4. We are in the process of building a lift.
5. If necessary, install springs and shock absorbers.
6. We mount the working element of the machine.
7. We connect all the contacts, install the drill.

When assembling the machine from a finished drill, it will be easier for you to work.

All that is required of you is to create a strong frame with the ability to raise and lower the drilling mechanism, to which the drill will then be connected.

There is no need to mess around with power supplies and engine assembly. You just need to properly fix the tool and connect it to electricity.

The assembly of the engine already provides for the installation of a power supply, a converter, and, if the engine has an indirect transmission of forces, mechanisms that are involved in their transmission.

Therefore, to prepare the second option, you will have to spend more time, effort and energy.

Yes, and certain engineering skills will not be superfluous either.

Most often, ordinary drills are used for drilling work, since drilling work is not particularly difficult. Therefore, in most cases, home craftsmen do not need drilling machines. Such units are especially popular among radio amateurs. However, even those who practice frequently repair work, may be interested in the drilling device. Buying industrial drilling machines and using them in everyday life is expensive. The problem can be solved quite simply. To do this, you only need to make a drilling machine with your own hands.

Drilling machine: working principle

Often there are situations in which a manual or electric drill is not able to complete the task. So, for example, for the manufacture of printed circuit boards, it is necessary to drill a lot of holes with a small diameter of 0.5-1 mm. It is not very convenient to perform such work with a drill, in addition, the drill may break.

With such work, a home-made mini-drilling machine can help out.

The design of the machine for drilling

Despite the fact that the design of the unit seems complicated, it consists of only four parts.

The main parts of the drilling machine:

• engine;
• transmission mechanism;
• working body;
• government.

In such a device, an electric motor using a transmission mechanism transmits movement to the working body, which is the drill. The working body is mounted in a cartridge, which is mounted on a rotating shaft (spindle).

The rotation is transmitted to the spindle by means of a belt drive. Using rack and pinion, the drill chuck can be raised and lowered by turning the handle.

The control unit of the unit is located on the front panel of the machine, on which there are buttons for turning on and off the electric motor. Depending on the required direction of rotation of the drill, the machine is turned on using any of the extreme buttons. You can turn off the device by pressing the middle red button.

A vertical screw-column is fixedly mounted to the base of the equipment. One of the handles is used to move the headstock around it. With the help of the second handle, the headstock is fixed in the desired position. Machines are equipped with a special scale, which reflects the depth of blind holes.

The drilling speed is set depending on what material the workpiece has. To do this, it is transferred to a pulley of a certain diameter belt drive belt, and a certain spindle speed is set.

The described design of the machine is one of the simplest. In production, drilling units with more complex schemes are most often installed.

Instructions for the manufacture of a drilling machine

Proposed homemade device can easily and with minimal effort drill holes at high speed. In this case, the depth of the holes made will be the same. In addition, it will be possible to adjust the position of the tool in the unit, so that it will be able to cut perfectly even squares from wood.

For the manufacture of a homemade machine need to prepare:

First of all, with your own hands you need to make base of the future drilling unit.

1. Cut out the main plate of a rectangular shape and four bars.
2. Attach the bars adjusted to its size to the edges of the form.
3. Fix the structure with clamps.
4. Stepping back from the edge of 1 cm, mark with a pencil the location of the screws, and drill.
5. Lubricate the attachment points of the base and bars with glue, connect the elements and fasten with self-tapping screws.

After the glue is completely dry, the clamps will need to be removed. The base is ready, now it follows start doing the hand of the machine.

1. On a rectangular board 40 cm long, it is necessary to make markings. To do this, along the base you need to draw a center line and step back from it in each direction by 5 cm.
2. At the marked distance, it will be necessary to attach the bars, each of which should be 17 cm long.
3. Attach the bars according to the markup and screw in the center with self-tapping screws.

For a more reliable connection, the elements can be pre-lubricated with glue.

At the next stage in the manufacture of a drilling machine, the most hard part unit, namely, its moving element. For its manufacture are taken two planks 25 cm long and guides.

The components of the structure are ready. All their lines, surfaces and angles must be even. Now the sleeve must be laid on a flat surface, and the base of the machine must be installed perpendicularly, and connected with a clamp. If a right angle is obtained, then the line of attachment of the sleeve and the base is marked, after which the parts are connected with self-tapping screws.

As a support for the drill will serve another plank of wood, which should be square. In its middle, you will first need to cut a circle, and then use the L-shaped brackets to attach the bar to the machine.

To make the support bar universal, you need to cut small square holes on four sides inside the circle, and drill longitudinal holes on the outside in the same places. After that, screws are inserted into them, with which you can securely fix a drill of any size.

To make the drill stable during work, the upper part of the support is made from another bar. To do this, a circle is cut out, and a part of the plank is cut off on one side. The rest is bolted to the moving structure.

The last element that needs to be installed in the machine is the stopper. It will be needed so that when drilling you can change hole depth.

A long threaded rod will serve as a stopper, under which a hole is drilled in the base of the structure. Then two holes are made in a small block of wood, one of which should be located horizontally and the other vertically. A screw will need to be screwed into the horizontal hole, part of which should come out on the other side. A screw plug is simply inserted into the vertical hole.

Now the bar must be installed between the movable installation and the base into which the long rod should be inserted. After passing the rod through the threaded plug, it must be tightened to the end.

Works on the manufacture of the drilling machine are completed. The device is ready for the drilling process.

Drilling machine based on asynchronous motor

You can create with your own hands electric motor machine from any unit that has served its time. Such a motor will become the mover for a mini-drilling machine. Best Option the engine is considered from drum washing units.

Since the engine from the washing machine is heavy and its power is higher than that of an electric drill, it will be necessary to prepare a powerful stand and base for it.

In order for the engine to vibrate as little as possible, it is placed as close to the rack as possible. In this case, it is necessary to additionally install pulleys with a belt drive.

For the manufacture of construction pulleys you need to prepare:

• hexagon;
• two bearings;
• gear;
• clamping ring made of durable steel;
• two tubes of small thickness, one of which must be with an internal thread.

To make the movable part of the transmission device of the unit, put a pulley on the hexagon and attach a metal tube with steel ring and bearing. These elements must be tightly connected to each other, otherwise they will collapse very quickly under the influence of vibration.

The adjustment complex of the device is made from a tube with cuts and a gear. The tube must be of such length that the cartridge can rise to the desired height. An axis with a hexagon is pressed into it.

It is quite difficult to make the described design with your own hands. For easier execution, it is recommended to assemble it by analogy with a machine tool with an electric drill. It is also worth noting that to achieve exact size holes using such a unit will not work.

Do-it-yourself work on creating a homemade drilling machine requires patience and perseverance. But those home craftsmen who really need such a unit will be satisfied with the result.
