Description of the universal sharpening machine. Universal sharpening machines Equipment for sharpening metal-cutting tools

The operation of equipment for cutting and processing metal leads to wear of the cutting tool. The restoration of its cutting properties and subsequent use in work became possible thanks to sharpening, which returns the part to its original sharpness and accuracy. For this purpose, it is recommended to use machines for sharpening cutting tools.

Design features and range of equipment for tool sharpening

Depending on the capabilities of the machines, a distinction is made between special and universal equipment. The first category also includes devices for sharpening drills, circular saws, cutters, etc. The design of such equipment is adapted to work with a specific cutting tool. The group of universal equipment includes equipment that is capable of sharpening several types of tools at the same time.

Considering the cost of modern machine tools and their working elements, the economic benefit from the availability of tool sharpening equipment becomes obvious. Its acquisition allows:

Avoid long-term equipment downtime;
Achieve high quality cut;
Reduce the cost of finished products;
Avoid a long search and waiting for the delivery of a new cutting tool;
Make efficient use of existing equipment.

When choosing machines for sharpening metal-cutting tools, you need to pay attention to a number of indicators, including:

Versatility or specialization;
Machine speed and productivity;
Installation and operating requirements;
Accuracy class;
Machine power and degree of automation.

Enterprises working with various types of cutting equipment should consider purchasing universal machines. They can be used to restore various cutting tools - reamers, countersinks, cutters, drills, taps, etc. A wide model range allows you to choose a device that is suitable for sharpening parameters, speed and performance, etc. On some devices, a diamond or CBN wheel can be installed, which sharpens the end or cutting edge. Setting the direction of sharpening - along or across - is manually adjusted. Semi-automatic machines have a hydraulic or electric drive to move the table, while the machine can be equipped with a coolant supply system. The complete set of universal type machines provides for a wide range of basic and additional working operations, which significantly increases the functionality of the equipment.

Why is it profitable to buy machines for sharpening metal-cutting tools in Moscow in Kami?

The KAMI Association invites manufacturing enterprises working in the field of metalworking for cooperation. The company's catalog contains a wide range of cutting tool sharpening machines from the world's leading manufacturers. All equipment is sold on terms of quality assurance and favorable prices. You can ask questions of interest by calling the specified phone number.

In most cases, universal industrial and household sharpening machines are used to sharpen all kinds of joinery products with their own hands.

Household mini-sharpening units for the home, for example, a universal table-top sharpener for flat knives, can work with planer knives, chisel blades, etc.

In addition, a homemade sharpening machine can be used to sharpen skates, and you can also sharpen an ax with it.

1 Varieties of sharpening machines

Sharpening machines presented as a tool for processing can use a cone or stone.

A multi-purpose homemade mini-grinding machine (grinder) can be used within the workshop or at home, and with large volumes of work, it is more rational to use industrial units.

Universal grinding machines using abrasive wheels (stones) or a cone for processing can be designed to process:

drills;
cutters;
circular saws;
knives;
band saws;
incisors.

Drill sharpeners can be used in a workshop or at home. Its stone allows processing of small tools (blades, cutters, drills).

Some universal modifications allow you to sharpen an ax or are used for processing the edges of skates.

A homemade mini-grinder (grinder) equipped with manual adjustment allows you to work with small diameter tools of 3-18 cm with your own hands.

Sozh allows you to achieve high quality processing of the edge of the skates, sozh can also be used in cases where the ax is sharpened. Such a homemade adjustable grinder can be used for twist or pen drills.

The taper of the working element guarantees the desired angle of the resulting edge of the blade. A home-made grinding machine for table cutters, using soj, helps to make professional sharpening with your own hands.

Flat knives such as skate blades can be machined with the Tormek t7 machine, or the Kolner kbg 200 370m multi-purpose grinder can be selected for this operation.

The working stone of the Kolner kbg 200 370m unit, as well as the Tormek t7 units, allows, due to the high number of revolutions, to process at home not only the ax or the surface of the skates, but also cylindrical, spherical, oval or arch-like shapes.

The caliber of the part processed by the stone of the Kolner kbg 200 370m unit, the Tormek t7 device or the 3v642 machine can range from 2 to 28 cm.

A mini-configuration grinding and sharpening machine with soot applied to the cone contributes to the fact that flat-type cutters are sharpened with their own hands.

Devices for sharpening circular saws with their own hands on wood differ in their functionality from analogs 3v642 or Tormek t7.

The abrasive (cone) of such mini-aggregates is diamond-coated. Such stones are processed at an angle from 0 to 30 ⁰ with a maximum number of revolutions up to 2000 per minute.

The choice of modification allows you to carry out the process in manual or automatic mode. At the same time, the caliber that the cone possesses allows you to process the front and rear edges of each saw tooth on wood with your own hands at home.

Like the common modifications of the Tormek t7, the presented universal unit makes it possible to sharpen the blade not only of a saw for wood, but also of a band saw.

The grinder can be programmed as on a lathe, this helps to select modes and the number of revolutions.

2 Design and principle of operation

Grinding machine Tormek t7, multi-purpose unit 3v642 and other similar elements, circles which are 200 mm in diameter, are equipped with electric motors.

Before using the scheme to make such a device with your own hands, it is necessary to take into account the nuances of the grinding and grinding machine.

The axis of the 3v642 electric motor is installed with an offset to the right side by several degrees. This feature helps you sharpen an ax or a wood saw with your own hands quickly and with good results.

A grinding and sharpening cone or abrasive wheels is attached to the motor shaft of a 3v642 or Tormek t7 device. The cross feed takes place due to the unit on which the stones are placed (abrasive wheels).

If you need it yourself to make a device similar to the 3v642 or Tormek t7, then first of all you need to choose the caliber of the stone, which will differ the circles and the cone. It is also important to consider that the transverse motion feed is carried out during the operation of the unit.

The unit, both on the turning and on the grinding and grinding unit, is located on the guide. The grinding and grinding machine functions by means of a worm gear located on the bed.

The holder of the 3v642 multi-purpose grinder for the home has a handle. In order for the 3v642 table grinder to correctly process the saw teeth on wood or skate blades, a special attachment is used that is attached next to the holder.

It should be borne in mind that before choosing a desktop device for the home, you need to pay attention not only to the number of revolutions, but also to a special handyman.

It will allow you to work with all kinds of locksmith tools - drills or chisels, and you can also sharpen an ax at home with it.

2.1 How to use a sharpening machine

The classification of types of work on a turning or sharpening unit has several positions:

with holder;
with attachment for radius processing;
with a handyman.

The first option allows you to choose for processing tools designed for working with wood - planers, chisels, chisels, etc. It is also recommended to use the required amount of CO2 in the process.

Before making a choice of the operating mode and setting the required number of revolutions, set the machine slider to the extreme left position.

After that, a grinding and grinding cone is attached. The U-shaped bracket and clamping screws are installed with an orientation to the caliber of the part. This must be done at the edge providing the removal of the spent chamfer.

In order to sharpen the ax or the edge of the skates, it is necessary to place the brackets parallel to the axis on which the cone is attached.

In this case, the circles can be placed with an interval of 2-3 mm. Then the switch turns and the grinding wheels start moving. The operator of the skate sharpening machine can then adjust the speed.

To do this, the transverse gear gradually rotates, and the edge of the tool with which the ax is processed is brought in so as to ensure a light touch.

The abrasive wheels begin to move along the blades of skates or other parts. Next, 2-3 longitudinal movements are performed along the blades of the skates, during which the grinding-abrasive wheels are moved back to their original position.

You should also not forget about the periodic use of sozh, which requires a sharpening machine for flat knives. When carrying out radial sharpening, a special attachment is used to help get a spherical chamfer on the edge of the part.

Before starting the action, if necessary, you need to make a choice of such a value as the caliber of the circle. After the selection is made, you need to release the slider and disconnect the clamping type brackets.

Despite the complexity of the work, such a unit is more efficient than a disposable manual sharpener.

A device for sharpening cutting tools is necessary for completing both a large production and a home workshop. However, this does not always require the purchase of a professional grinder. For processing the cutting edges of knives, scissors, chisels, etc. amateur equipment is suitable.

Working principle and classification of grinding equipment

All sharpening machines work according to the same principle - the blade of a knife or other cutting tool contacts the abrasive, as a result of which part of the material is removed. This leads to the formation of a sharp edge.

Several types of construction are used to achieve this result. They differ from each other not only in configuration, but also in performance. For in-line production, the volume of work performed and their quality are important. In household models, the quality of knife sharpening plays a primary role.

Depending on the layout, the grinding machines can be of the following types:

with holder. It is necessary for fixing the machined tool. The approach of the edges to the abrasive is carried out by the mechanical part of the machine;
with a prefix. It serves as a retainer to stop the main part of the tool. Contact with the sharpening part of the equipment is carried out by manually displacing the part. In this way, radius processing occurs;
with a handyman. It is similar to the prefix, but has more advanced functionality. In household models, it can be multifunctional and have several types of grooves to accommodate different types of blades.

To increase the functionality of the equipment, it can have several design additions. In particular, the use of several abrasive wheels with different grain size, the possibility of automatic or semi-automatic work, various auxiliary devices to improve the quality.

Additionally, some sharpening machines can perform work on grinding workpiece surfaces. But for this, they must have appropriate devices for fixing the blades.

Types of household grinders

Household grinding machines are one of the most popular types of equipment. Unlike professional models, they have a simple design, which ensures a long period of maintenance-free operation.

The main requirement for these structures is ease of use and reliability. But despite this, manufacturers are trying to make them truly universal. In practice, achieving multifunctionality in a small-sized structure is very problematic. Therefore, professional DIYers prefer highly specialized equipment for sharpening cutters, drills or knives.

There is a conditional division of machines for working at home into the following categories:

according to the principle of operation - with an electric motor or manual;
by the number of operations performed - multifunctional with adjustment or with a narrow focus of work.

Moreover, each type of sharpening machine has its own characteristics. They must be taken into account when choosing equipment for the home.

The quality of the blades of a knife or chisel depends on the type of abrasive used. For each type of material, it is necessary to select a sharpening disc with specific parameters.

Manual grinding machines

It is impossible to fully call a device for sharpening knives or scissors as machines. The main reason is the low degree of work automation. But despite this, hand-made models are very popular among home craftsmen.

To restore the sharpness of the blades, two cutting principles can be used - with a moving or stationary abrasive. In the first case, the setting of the degree of the sharpening angle is performed by changing the position of the abrasive, in the second, by adjusting the degree of contact of the blade with the bar.

Despite the low cost of such models and the ability to independently manufacture their analog, they have a number of operating features:

low productivity;
laboriousness of sharpening;
obligatory skills in the formation of the cutting edge. Moreover, the technology depends on the type of tool being processed.

The universal pendulum-type blade sharpener is ideal for cutting knives and scissors. Due to the possibility of changing the position of the abrasive relative to the surface of the tool and reliable fixation of the latter, the accuracy of the operation increases.

Factory equipment models

Factory models of sharpening machines equipped with an electric motor have greater productivity and ease of use. The main feature is the use of an abrasive disc as a processing tool.

Grinding machines of this type have a standard design. The body is made of sheet iron or polymer materials. The frame of models for home use is most often made of plastic. Inside there is an electric motor, on the shaft of which one or two abrasive wheels are installed.

Based on the design features, the grinding equipment can be divided into the following groups:

With templates. Machine tools of this type are universal. Using templates, you can sharpen knives, various types of blades, drills and some types of finger mills. For this, jigs with adjustment are added to the package to set the correct position of the cutting part of the tool relative to the abrasive;
With an assistant. Typically, this type of machine has one or two abrasive discs and handcuffs (stands) to stop the tool. Changing the degree of the sharpening angle is done manually, which requires certain skills from the worker.

Most of the models for home use are made with built-in templates. This allows, at a low skill level, to make high-quality sharpening of almost any tool.

When choosing a machine with the function of processing drills, you need to pay attention to the minimum and maximum diameter of the product, as well as the possibility of dressing.

Specifications

Before purchasing a sharpening machine, you need to familiarize yourself with its performance. It is also important to initially decide on all types of tools that will need to be processed. Most often these are knives, scissors, chisels, drills. As an example, we can consider the characteristics of the popular model of the universal machine "Energomash".

It can be used to sharpen almost any blade configuration. For this, grooves are provided on the body of the structure for the installation of one of the three conductors. Numerous adjustment mechanisms allow you to perform the operation to restore the previous sharpness of the cutting edges with high precision.

Main technical characteristics of the model:

rated power of the electric motor - 0.1 kW;
the number of revolutions of the power plant - 6700 rpm;
the maximum width of the formed sharpening is 51 mm;
processing of drills with a diameter of 2 to 10 mm;
dimensions - 22 * \u200b\u200b22 * \u200b\u200b17.5 cm;
weight - 1.8 kg.

Despite its small size, this machine can successfully process all types of household cutting tools. The disadvantages of this model include the relative unreliability of plastic conductors. During the execution of work, the clamping force should be monitored. Otherwise, deformation or breakage of the machine element is possible.

For sharpening knives, the design has a special jig, in which there is a function for controlling the angle of the blade position relative to the abrasive wheel. This parameter directly depends on the actual state of the cutting edge.

Features of operation

Before starting work on the sharpening machine, you must study the operating instructions in detail. It indicates the maximum width of the processed blades, the permissible diameters of the drills. Then the machine is preset. To do this, it is necessary to install the gearbox in the corresponding groove and use the mechanisms to set the cutting edge to touch the abrasive wheel.

In the process of work, it is imperative to use protective equipment - work glasses. As an additional measure, a transparent screen is used, if such is provided by the design of the machine. The pressure build-up on the tool during machining should be minimal. Otherwise, deformation or uneven material removal may occur.

At the end of the work, the machine must be cleaned of chips and metal dust. If necessary, the condition of components and assemblies is checked. It is imperative to control the degree of wear of the abrasive wheel.

As an example, you can see the capabilities of a multifunctional model of a sharpening machine:

Working with wood, metal, plastic and other materials requires a cutting tool. The assortment of such products includes separate categories of products in terms of dimensional, strength characteristics. In the process of processing, the cutting edges lose the necessary properties, they have to be sharpened regularly. The operation is not complicated and, with the exception of certain special types of tools, is done independently. The universal sharpening machine has gained wide popularity among craftsmen of various specialties. With its help, the characteristics of the cutting edge are restored.

Types of sharpening machines

There is a wide range of products of this type on the market. They also make machines independently. The equipment is divided according to its structural and operational qualities, regardless of whether they are made by hand or bought in a store. Universal sharpening machines can be of the following types:

mechanical devices are used in everyday life and for finishing the cutting edge. The machines are considered conditionally, since the physical strength of a person is used;
household machines for sharpening tools at home. They have a minimum of functions and a low-power electric motor;
semi-professional equipment. Sufficient power reserve for long-term operation with significant physical exertion. Equipped with additional accessories for targeted processing of hacksaws, chains for chainsaws, drills, circular saws, cutters;
industrial machines. High-precision equipment that allows you to sharpen tools of complex configuration with specified parameters. In production, universal CNC grinding machines are widely used, which increase the productivity and quality of the operations performed.

The most popular model for household use is the universal desktop sharpener. It enables home craftsmen to maintain high performance of construction tools, kitchen utensils, tools for processing the land. A wider variety of products are produced for industrial use. The accuracy of the work is due to the overall body that does not react to vibrations, the rigidity of the structure, which allows processing the cutting edge with a deviation from the nominal value of no more than a few hundredths of a millimeter.

For home use, the set of functions that a universal household sharpener has is sufficient.

On such equipment, you can quickly fix a dull knife, scissors, ax. The device operates from a 220 V network, and has a power that does not overload communication cables. Follow the safety regulations when performing any operation:

before switching on, check the integrity of the cable, the reliability of the nut fixing the grinding and abrasive stone and the strength of the accessories and the support table;
work in safety glasses and appropriate clothing;
do not handle parts in an unsupported position while suspended.

A universal sharpening machine is intended for sharpening metal-cutting tools, and it cannot be used for other purposes. For example, it is strongly discouraged to process the following materials at home:

glass, porcelain, stones;
carbide soldering;
plastics, rubber, rubber, polymers.

The above materials can be processed, but the configuration of the equipment for this is not standard, but a special one. These operations are done by trained specialists who know the specific features of grinding, who are able to choose the right abrasive or other wheel. In production, complex surfaces made of composites, glass, porcelain are processed with specially designed tools. Often a CNC universal sharpening machine is used to comply with the grinding conditions.

Used abrasive stones

Choosing a universal grinding and sharpening machine, the types of upcoming work are assumed. In addition to design differences, equipment performance depends on the replacement tool. The range of grinding wheels includes a large number of items. They are divided into the following categories:

circle diameter;
type of abrasive;
grain;
circle shape;
the diameter of the seat on the machine.

Household sharpeners use general purpose corundum particles. They are versatile and are successfully used for household needs. The bench-top sharpening machine is completed and can serve for years if used irregularly. If it fails, remove it from the shaft and check the inner diameter before buying a new one or specify the size in the instructions. It is also important to know the outer dimensions in order to avoid the risk of acquiring an unsuitable circle for a particular model. Popular standard seat diameters that a universal tool sharpening machine can have:

10 mm - a circle for sharpening chains, hacksaw blades;
20 mm - a circle of the old standard, but is still produced specifically for sharpening machines;
22 mm - a standard widely used in the world, in particular, abrasive discs for "grinders";
32 mm is a common diameter for grinding and grinding equipment.

There are other standards, but less often. For industrial equipment, a wider assortment is assumed, since special industry standards are applied there and the list of work performed is much larger. Universal cutting tool sharpening machines are often equipped with adapter rings to adapt to the required diameter.

For certain jobs, the grit size of the abrasive is important. Coarse particles are good for primary processing and rapid removal of significant metal thicknesses. But such wheels are not suitable if a universal sharpening machine is used for milling cutters of complex shapes, for small diameter drills and grinding and polishing works. Fine abrasive particles work more slowly, but the surface finish is much better. Such circles are used to bring out the exact cutting edge of turning tools, mills of complex configuration.

Automation is widely used in technological production lines. Electronic management and control over the execution of operations and in equipment of a wide profile are being actively introduced. Semi-professional universal sharpening machines are increasingly equipped with such devices. They are widely used:

in small industries;
in car services;
in craft production;
in the home workshops of private entrepreneurs.

A self-respecting master of almost any specialty has at least a simple universal machine for performing elementary operations. Those who approach the issue of housekeeping are trying more seriously to purchase productive and convenient equipment with good functionality, a set of abrasive wheels and additional accessories for sharpening cutting tools.

High-strength abrasives are allocated to a separate category. They are used for grinding tools with carbide elements. A universal sharpening machine with a diamond or CBN wheel is widely used for restoring cutting discs in the woodworking industry, the production of metal-cutting tools, for example, cutters, drills, cutters.

Sharpening technologies and accessories

Grinding and grinding equipment performs a significant list of operations, from bringing household items into proper condition to processing parts of spaceships. Additional devices significantly expand processing techniques and improve the quality of the work performed. The following structural elements of the machine are referred to them;

support table or attachment. The simplest and most widely used method to hold the workpiece in position. Among the disadvantages is the inability to control the angles and dimensions. The operation is carried out exclusively under visual control;
handyman. The evolution of the development of the support table. It can have guides and grooves with a certain pitch or angle. Allows you to process a part with specified parameters;
holder. The device can have a movable part, where the firmly fixed part moves in a given direction. A device that facilitates the grinding process and allows you to accurately control some of the dimensional characteristics of the workpiece being processed;
Copier. A mechanical attachment borrowed from a lathe. It is used for processing complex-shaped parts according to a pre-set template;
CNC. The process is fully automated. The part or abrasive wheel moves strictly along a given trajectory. Modern technologies make it possible to program processes on public computers using special programs and applications.

The industrial sharpener is equipped with a cooling system. This speeds up the operation by preventing the part from overheating. The fluids used in the equipment also have a lubricating effect, which makes the surface quality higher than when processing with dry abrasives. In particular, a machine for industrial cutters must be equipped with a similar device. The cutting edge must meet strict requirements for shape accuracy and surface finish.

Geometry is also important when sharpening drills. It is almost impossible to achieve the required values \u200b\u200bmanually. Controlling angles and alignment visually is an unattainable task. Chainsaw chain sharpeners are very popular. Stable demand for hacksaw blade restoration devices. It is impossible to perform all the above operations without additional mechanisms with the required characteristics and proper quality.

Today, a multi-purpose sharpening machine is an irreplaceable mechanism that can provide irreplaceable assistance during certain technical work. Experts advise not necessarily to buy an expensive professional sharpening machine right away - it all depends on the needs (quality, volume or speed of sharpening). For example, when processing the edge of a simple knife or scissors, an amateur inexpensive machine is quite suitable, but if this is a lathe workshop where you need to perform the volume of work, then a professional-level multifunctional sharpening sled is just what you need.

Types of grinding machines

There are many types of household sharpeners that are used depending on the needs. Professional models have more complex structural mechanisms, but they are used much less often than simple models (almost every home craftsman has them).

The main requirements of grinding machines are convenience and ease of use, while their reliability must be at a high level. Most manufacturers are trying to make sharpeners more functional and versatile.

But, based on the variety of tools that lend themselves to sharpening - it is quite expensive to achieve 100% versatility.

Therefore, most universal grinding machines are designed to process components such as:

circular saws;
lathe cutters;
knives (cutting or hunting);
cutters;
drill.

Machine categories

In practice, universal grinding machines can be divided into specific categories.

Based on the drive principle:

hand-held devices;
mechanical, equipped with an engine.

Based on the number of operations that the device performs:

narrowly focused;
adjustable.

Each specific household type of equipment may have individual adjustments. It is important to consider this when choosing a tool for further work.

Indicators of the quality of processing the end of the blade, regardless of whether it is a chisel or a cutter - it all depends on the selected abrasive wheel. It is worth noting that each type of metal requires an individual selection of the grain size of the abrasive wheel, which also has its own parameters.

Characteristics of sharpening machines

Important factors that influence the choice are:

feature of the size and dimensions of the machine;
network connection option;
installation features;
sharpening speed;
materials and class used for sharpening;
level of versatility;
accuracy of work performance;
equipment power indicators.

Most machines are equipped with a variety of electronic and electrical devices. This determines their level of professionalism and versatility. As for the installation of the machines, this does not require much, just a flat horizontal surface.

A universal sharpening machine, depending on the actions performed, can be classified in different ways, divided into certain groups:

mechanical devices with a narrow focus;
universal sharpening machines.

The first group refers to equipment designed for sharpening the edges of specific cutting tools to which they belong (hob cutters, drills, band and disc-type saws and other active additions to other equipment).

The second group of devices is equipment that is required for sharpening the edges of a large number of tools. Most of the machines are equipped with adjustable mountings for increased convenience and safety.

Features of operation

Before starting the sharpening process, it is important to master certain adjustment skills using the rules of the instruction. And it is also important to secure the process using protective equipment (glasses or gloves). The instructions have certain restrictions, this applies to:

maximum width;
maximum drill diameter.

And also before turning on the universal sharpening machines, it is important to make preliminary settings, to set the appropriate distances between the blade and the sharpening wheel (using the touch effect).

A transparent screen is often used as additional protective equipment (it is provided during the production of equipment).

It is important to clearly define the sharpening angle, this is often done using adjustable sliders. In universal machines, the workpiece is fastened for sharpening using staples. They are made in the form of the letter "P". Fixation takes place with stop bolts.

After the first start-up, it is important to ensure light contact between the wheel and the part. In most general purpose machines, the operator's left hand should be responsible for the cross feed and the right hand for the longitudinal movement of the part.

It is important to ensure that the movement process is smoother. The blade should move along the edge of the working part of the circle. When using attachments when sharpening parts of the radius type, it is important to correctly fix the workpiece using a clamp.

It is important to pay attention to the metal from which the workpiece is made. Given this property, it is important to correctly choose the number of revolutions with which the cutting wheel rotates. If this parameter is exceeded, the workpiece can be “set on fire”.

Factory models of universal grinding machines

Many DIYers can make homemade equipment designs, but factory-made universal sharpeners will always excel in quality and workpiece processing speed.

Most factory universal grinding machines have a similar design. The body is made of polymer-coated iron sheets. If the device is intended for home use, then the frame can be made from a certain type of plastic.

The disk drive is an electric motor that rotates the gearbox (but there can be designs without it).

With regard to the number of abrasive wheels, we can say that there are several of them in universal equipment.

This is required for better processing of simple or metal cutting tools.

Sharpening equipment is divided into certain groups:

Universal machines have templates. When using such devices, knives, cutters or different types can be sharpened. To increase the convenience of the process, the complete set includes jigs for adjusting the angle and position of the workpiece relative to the plane of the circle.
With an assistant. When equipping machines with two or more abrasive wheels, it is important to choose the right supports for the stop. They are unusual, the degree is changed by manual adjustment (such devices require appropriate skills).

Many models of universal grinding machines that are designed for use in the home workshop are made with the templates mentioned above. This makes it possible, in the absence of skills, to secure the process and perform the work better.
