The capabilities of the grinder can be expanded not only through various attachments, but also by installing it on special homemade devices. As a result, you can get a cutting machine, with which you can accurately cut metal workpieces at any angle. In addition, the grinder can be mounted on a carriage, and the resulting machine can be used for cutting sheet steel.

In order to understand how to make a cutting machine from an angle grinder (angle grinder), you can look on the Internet various drawings. But they will be of little help, since all the dimensions of the parts will still have to be selected based on the size of the grinder you have. Options for making devices can be either simple or more complex, requiring the ability to operate a welding machine.

Option 1

To make this device for an angle grinder, you will need welding skills. So, you need to do the following.

First, cut 2 small pieces from the corner (50x50 mm). Their size is selected based on the dimensions of the gearbox of your angle grinder.

Next, drill holes with a diameter of 14 mm in them and screw the corners to the angle grinder, as shown in the following photo. If you do not have suitable bolts, you can use M14 threaded studs. Just be careful that the bolts are not too long. Otherwise, in some models of angle grinders they may cling to the impeller located in the gearbox housing.

Without removing the corners from the angle grinder, secure them by welding. After this, the corners can be removed and scalded well.

Clean up welds grinding attachment for grinder.

Then you need to make rotating lever support, on which the device will be attached. To do this, select 2 pipes of such diameters that one can without special effort enter another.

For a more precise cut, you can glue masking tape to the tubes and draw a line on it.

Then, turning the tube, carefully cut it with an angle grinder. A piece of pipe with a smaller diameter should be 20 mm shorter (the thickness of 2 bearings) - it will serve as a spacer.

For a thicker pipe, select 2 suitable ones for it inner diameter bearing. After this, insert the thin tube into the thick one and press the bearings on both sides.

Then insert the pin into the bearings. Be sure to place a washer in front of the nut.

When the rotating mechanism is ready, you need to weld a small piece of corner to it.

The next stage is done rack for rotary mechanism from the same corner 50x50 mm. To ensure that the pieces are the same length, the corners can be tightened with a clamp and trimmed.

Also, without unscrewing the clamp, they can be drilled immediately.

Attach the corners with drilled holes to the ready-made rotary block using nuts.

Weld a longer corner to this rack, as shown in the following photos.

Now you need to decide lever length, on which the angle grinder will be attached. This is done by selection based on the dimensions of your angle grinder. You can lay out the parts on the table and calculate the approximate dimensions of the lever, which is best made from 2 square segments profile pipe 20x20 mm.

The pipes also need to be clamped with a clamp and cut to the same size.

Once all the parts are ready, they can be welded together, as shown in the following photos.

In the next step you can attach to finished design Angle grinder and check again what came out of it.

Ready pendulum mechanism for an angle grinder can be easily installed on any flat surface, For example, on the workbench. Also this design can be installed on a table specially made for it. For a more rigid fastening of the mechanism, you can weld small sections of the corners on both sides of the long corner and drill holes in them.

In the following photos you can see how a ready-made angle grinder attachment is mounted on a table (in this case a metal frame is used).

It is very important to set a right angle between the plane of the cutting disc and the plane of the table. Place the square on the table and move it towards abrasive wheel, installed on the angle grinder. If you initially managed to weld the fixture so that the angle between the planes was 90 degrees, then that’s good. If you notice a deviation from right angle in one direction or another, then the situation can be corrected with the help of a crowbar or a long profile pipe, for example, 60x20 mm.

To prevent the part from moving when cutting, you can screw a corner onto the table that will serve as a stop. Also, for precise cutting, the table can be easily improved with a simple vice, made from a nut welded to it and a pin of the required length screwed into it.

Next you need make a protective casing. It is done taking into account the maximum diameter of the cutting disc, which can be installed on a specific model of angle grinder. To make it easier to determine the size of the casing and the places for its attachment, you can first make a template, for example, from a piece of cardboard.

In this case, the casing will also serve as a limiter for cutting tool, preventing it from going too deep into the table while processing the part.

It would not be superfluous if for a lever with a grinder attached to it make springing. In this case, it's easy to do: insert with reverse side rod with a smaller tube and attach a spring to it, as shown in the following photo.

At this point, the manufacture of a cutting machine with your own hands, in which an angle grinder is used as a drive, can be considered complete.

Option 2

The next version of the device for the grinder, with which you can cut metal workpieces, is done as follows.

Thus, we got a simple cutting machine. To add additional rigidity to attaching the device to the lever, you can use clamps by first placing, for example, a wooden block between the angle grinder body and the pipe.

For precise cutting, so that the workpiece does not move, you will need to screw a corner to the table.

For a little Bulgarian A similar version of the device is also suitable, only the angle grinder will be attached to a metal strip: on one side with a bolt to the angle grinder itself, and on the other with a clamp.

For powerful angle grinders the device is made according to the same principle, but from profiles bigger size than in the pictures above.

It is not necessary to use dumbbells as a counterweight. All you have to do is find a suitable spring.

Option 3

This device option is the simplest for making it yourself. It is made without a traditional stand (stand) for the rotating block. You only need one door canopy, a metal strip and an elastic band (you can use an elastic band from a hand expander).

The design is done as follows:

• in the metal strip, on one side, drill holes for the door canopy, and on the other, for a bolt, which will be used to fasten the strip to the angle grinder;
• screw the angle grinder and canopy to the strip;
• screw the canopy to the table;
• fasten one end of the elastic band to the edge of the table, and the other to the holder (handle) of the angle grinder.

In just a few minutes you will get a high-quality cutting machine. This device is also mobile, because it can be carried with you in a suitcase with tools, and, if necessary, mounted on any flat surface.

When installing this device, do not forget to attach a corner to the table to rest the workpiece against it.

Cutting sheet hoists using an angle grinder

To cut sheet metal you will need to purchase special carriage, which moves along a guide (profile square pipe).

But as practice shows, the cost of a good carriage is high (more than $100), so you can make it yourself. Because the this process quite difficult to describe, you can understand the manufacturing technology of this slider from this video. Using the device you can cut not only steel, but also ceramic tiles, and porcelain stoneware.

Please note that cutting ceramics generates a lot of dust. Therefore, it is recommended to adapt a dust collector with a pipe for a vacuum cleaner to the angle grinder casing.

How to make a homemade dust collector

The simplest dust collector for an angle grinder can be made from plastic bottle from motor oil.

The nozzle is made as follows.

After these simple steps, you can use the grinder to process materials that create a lot of dust when cutting.

The well-known angle grinder, with its cutting, grinding and cleaning capabilities, has turned out to be capable of several more functions. Expanding the functionality requires doing some work with your own hands in order to obtain the necessary devices for the job.

This device is a small machine that makes cutting easy, safe and very precise. metal pipes, profiles or rods. It consists of a base or small table attached to the ground or to a metalworking table.

The machine is assembled in a simple sequence:

• install a hinge on the base;
• We weld the supporting pipe to the hinge;
• We attach the U-shaped plate for attaching the grinder to the pipe;
• We put a rubber handle on the supporting pipe;
• install the disk and check its position.

As a result of some simple work, we got a machine or stand for an angle grinder. Now the grinder can rise and fall down on a hinge onto the part installed for cutting. In order for the angle grinder to rise up without loads, we install a spring on the pipe.

It is necessary to install two fixing angles on the table. At the base of one corner we make a groove around the circumference for a bolt. It will be needed when a pipe or profile needs to be cut at a certain angle. Then we install this corner with a slot at the same angle to the plane of the grinder’s cutting disc.

Parallel to the corner with the arc slot, we install a corner that can be moved towards the part to fix it on the table. The pipe or profile will simply be inserted between two corners. This is enough to perform fast and precise cuts.

By installing a supporting transverse metal bar on the machine table, you can strip the material using a steel brush mounted on the angle grinder shaft.

Simple cutting machine + (Video)

You can make a cutting machine based on an angle grinder yourself in one day. For the machine it is necessary to select a frame - a metal base plate. Attach the hinge to it. Weld a supporting frame with a plate for attaching the grinder to the hinge.

Any suitable part can be used as a hinge. In this case, the hinge is made of rotary hinges passenger car. The hinges have already served their purpose, but they fit the machine very well.

Do-it-yourself wall chaser from an angle grinder + (Video)

A groove is a groove that must be cut in the wall for installation electric wire or cable. The difficulty of this work is that the groove must be of constant width and depth. Then the wire will be laid evenly and less mortar will be required for laying.

A wall chaser is rarely used in practice, so buying one for your home will be expensive. But it can be made on the basis of an angle grinder - our favorite grinder.

The main task is to install two diamond blade on the angle grinder shaft with a distance of at least 1 cm:

• install the first disk and secure it with a nut;
• install the second disk and secure it with a nut;
• measure the resulting distance between the disks;
• install protection on the grinder;
• checking the work.

But, if for some reason it is not possible to install two disks on the shaft, the groove can be cut and the usual method one installed disk. You'll just have to cut a second parallel line.

Work with a wall chaser is carried out indoors. This creates a huge amount of dust. Even a respirator can't save you from it. To eliminate this negative phenomenon, it is necessary to make a protective casing that would cover both disks and have a pipe on top for connecting to a vacuum cleaner. A similar device is available on electric jigsaws for collecting small sawdust.
Sometimes lovers of rational use of tools attach 2 or 4 rotating rollers to this casing. When the wall chaser moves along the surface of the wall, it will move on rollers without creating additional stress on your hands.

To make a tool for a wide groove, it is necessary to make special bushings to mount the disks to the desired width. With such a wall chaser it will be possible to make grooves for laying pipes.

But the protective casing will also need to be made wider. On the casing of the wall chaser for both wires and pipes, it is necessary to install a screw for adjusting the immersion of the cutting tool into the wall. In this case, the casing will consist of two parts connected by a hinge and a immersion adjustment unit.

Grinder milling cutter + (Video)

Sometimes there is a need to mill a hole or surface, but there is no familiar milling machine operator, and there is nowhere to look. But there is an angle grinder - an angle grinder. This is the solution to the problem. We choose a machine from two options - a movable machine and a movable table.

In the first case, we secure the workpiece or material that needs to be milled, and the grinder is attached to vertical plane to the frame. On the frame it is possible to move the plate to which the grinder is attached left - right and forward - back. In other words, we can move the angle grinder relative to the workpiece.

In another version, the grinder is fixed rigidly, and the workpiece moves, by analogy, left - right and forward - back. These are the main directions for milling. For milling along the up-down axes, it will not be difficult to supplement the device.

Having chosen the machine option, you can begin implementation. The only place, which will require the involvement of a turner - a cutter holder. It is turned from a hexagon of at least 16 mm, because the thread of the grinder is 14 mm. Collet type holder. It is easy to manufacture and does not have large runouts. A regular jaw chuck does a worse job.

The advantage of such a machine, like all machines based on an angle grinder, is that they can easily be transformed back into an angle grinder. As a type of router, you can make a drill from a grinder.

Pendulum saw + (Video)

It’s not difficult to make accessories for an angle grinder with your own hands. You don't even need drawings here. It is enough to know the principle that is embedded in a particular machine. A pendulum saw based on a grinder is no exception. This is the same cutting machine, but its weight is distributed almost in half.

It is somewhat similar to a children's swing. The frame is located on the movable bushing, and an angular Sander. The counterweight can be any weight in combination with a return spring.

Represents universal tool, which can be used to cut tiles, stone, metal. It is also suitable for sanding surfaces. Versatility of this instrument is that it can be converted into a stationary machine.

In some cases, a design is required that simultaneously combines the functions of an angle grinder and a cutting machine. The problem can be solved by purchasing a separate machine, but this will extra costs. In addition, such structures are made of duralumin, which does not hold the angle grinder in place well, resulting in poor quality work. The problem can be solved by making a special device. You can do this yourself.

Purpose of a device for cutting metal and its design

The grinder fixture is manufactured to perform the following tasks:

• smooth cutting of knife steel;
• cutting fullers on blades.

A self-made device for cutting sheet metal includes the following components:

• air intake that removes dust;
• clamping carriage with handle;
• pendulum mechanism with disk.

The air intake removes dust. It is connected to the chip vacuum cleaner using a hose. When the device operates, dust enters the hose and moves through it into the chip vacuum cleaner, which prevents air pollution in the room.

The clamping carriage with handle consists of a plate 3 mm thick, 15.5 cm long, 11 cm wide. In the middle of the plate there is an M8 thread for fixing the handle. There are two cuts on the plate. Under the plate there are two steel sections, holes with M6 threads are made inside the squares, bearings are installed on the threads, under which screws with a diameter of 6 mm are used as axes.

Typically 6 screws are used for the clamping carriage. The carriage handle is a removable mechanism designed for greater convenience when working with an angle grinder. During the metal cutting process, the carriage itself slides along the guide.

Tools needed to make a fixture

To make accessories for angle grinders for cutting sheet metal, special attachments are required. You can make them yourself. You will need the following tools:

• metal corner;
• electric drill with drills;
• duralumin steel plate;
• discs with a diameter of 125 mm;
• self-tapping screws;
• wooden bars.

General procedure for making fixtures

To begin with, metal is taken and a plate is cut out of it. Then an angle is made from the resulting plate. To do this, first a triangular cut is made, and then the workpiece is bent at an angle of 90 0.

IN metal plate 6 holes with notches are made. The holes are necessary for screwing self-tapping screws into them, with which you can install the corners and the handle. Notches in the holes are necessary for screw heads. Optimal size fastening elements - 3*35 mm.

Then the metal corners are installed. The important thing is at what angle the first corner is bent. It should be bent at an angle of 60 0. Otherwise, the structure will not be able to be fixed. When the corners are installed, the tools are attached to them.

To connect the parts of the structure and the tool itself, use bolts and nuts on one side and a handle on the other. Bolts with nuts are needed to prevent the screw of the structure itself from unscrewing when cutting metal.

The need for a bed

Any grinder needs a bed. Beds are devices that facilitate the work of the master and allow him to cut materials without unnecessary effort.

The manufacture of the bed proceeds as follows:

• making a wooden box;
• removing the grinder casing;
• installing the disk on the instrument;
• fixing the disk to the side wall of the device itself;
• setting a mark at the gap location.

Other options for accessories for grinders

For ease of use, angle grinders (angle grinders) are equipped with a vice or a workbench. These devices allow you to fix the instrument itself motionlessly.

By installing a separate disk, the grinder can be converted into a sharpening machine, fixed with a mount.

A convenient way is to install disk sawmill from Bulgarian. The result is a sawing machine designed for seasonal work, which can be quickly disassembled when necessary.

You can make a miter box from a grinder. To do this, you will need to make a rotating tabletop for the angle grinder. Then, the tabletop is fixed at the desired angle, a disk is installed and any material is cut. With this tool you can cut materials from wood, metal, stone.

If the shaft of the grinder is brought into the hole of the workbench and a chuck for milling heads is put on it, you will get a stationary grinder with a router.

When you attach a stop, which has slots, across the disk itself, it becomes possible to process metal parts, holding the product itself in your hands.

The grinder can also be used as a wall chaser. To do this you will need a nozzle with a solid foundation. With this device you can cut walls. In this case, the device will move along the wall more smoothly, and during operation it will not require too much physical effort. It is recommended to equip the wall chaser with a closed case with a hole intended for connecting it to a chip vacuum cleaner.

Making a protractor for an angle grinder

The protractor is necessary equipment for the Bulgarian. It is useful for cutting metal. This device allows you to accurately calculate the cutting angle. You can do it yourself. The protractor consists of the following parts:

• loops;
• corner;
• bolt.

The protractor works in the following stages:

• installing a guide angle on the tile;
• tightly pressing the workpiece itself to its shelves;
• cutting metal with gentle pressure on the cutting elements of the disc.

Before starting the manufacture of any device for an angle grinder, it is recommended to draw up detailed drawings of the parts and the installation process itself.

Cutting metal or other hard materials is done with an angle machine, which is popularly called an angle grinder. This fairly simple tool allows you to cut many materials, with various types disks. However, keeping angle machine in the hands, an even cut is not always achieved.

It is for this reason that there are many different devices, thanks to which it is possible to fix the grinder and make more accurate sawing. But basically these are pendulum-type devices that allow you to cut workpieces crosswise, at a certain degree, both vertically and horizontally.

As for cutting sheet blanks in length, here it is more likely to use a technology similar to disk hand saws. There are such devices on sale, although with some skills you can do this yourself. It is important to understand the principle of operation of such a device. And if you need it in your work, do something similar, using materials that you have or are more accessible.

There are two options here. The first is to secure the grinder under the table, leaving part of the cutting disc on top through the slot. Perhaps this method is simpler, but if the workpiece does not go smoothly or it is quite heavy, then the cutting disc can jam and break. Therefore, this option is used for sawing wood with a metal circular saw.

As for sawing sheet or other metal in length, a device is needed that secures the grinder to a sliding frame, such as a well-known circular saw, with the ability to adjust the depth of cut.

As a guide, you can use either simple slats or metal corners attached to the table using clamps, or complex devices that have bearings on the carriage that roll along the guide. It is clear that the design will be developed taking into account frequent or one-time use.

It is important, with such a cut, to set up the entire mechanism. It is important that the cutting disc runs parallel to the cut, which is not always possible when installing an angle grinder on the device. Therefore, you need to pay attention to this, since the disk rotates at high speed, which is not safe, plus if the cut is not even, the width of the cut increases.

An angle grinder, simply a “grinder”, has three main areas of use.

• Cutting hard materials;
• Grinding with abrasives;
• Cleaning surfaces with brushes.

The technology involves holding the angle grinder with your hands while working.

However, for convenience and expanding the capabilities of the tool, many devices have been invented. Let's carry out short review:

Tripod for angle grinder

Industrial tripods for mounting angle grinders. Allows you to make from an ordinary grinder cutting machine

This mini machine solves the main problem when working with an angle grinder: if you hold the tool with both hands, it is extremely difficult to fix the workpiece. In this case, an angle grinder with a cutting disc is controlled with one hand, and with the other you can hold and move the piece of metal being cut.

Moreover, the tripod allows you to install correct angle cutting, and the disk moves strictly vertically. The work is done efficiently and safely.

Craftsmen have long learned to make accessories for grinders for cutting metal and other solid compact workpieces on their own.

The beds are assembled from metal profile, car shock absorbers, or even plywood. A well-made machine is no less reliable and safe than a factory one.

IMPORTANT! When working with any machine - factory or homemade, you must remember the correct position of the protective casing.

If your structure is strong enough and provides operator protection, you can use a tripod for sawing wood. The main thing to remember is safety.

In this case, main reason injuries - an uncontrollable grinder that escapes from the hands when the disc gets jammed in the wood has been eliminated. But the disc itself can still cause injury.

Homemade tripod for mounting an angle grinder.

Therefore, when manufacturing such a device, it is better to make the switch non-fixed. For example, in the form of a foot pedal. Then you can instantly turn off the power if the device gets out of control.

When there is no need to work with wood, but only need to cut a large number of metal blanks – there are more simple options.

Such a mount can be made in an hour, and the ease of use will increase by an order of magnitude. If you know how your hands “fall off” after cutting fifty pegs from metal corner– this design is for you.

Clamp for grinder

The second most popular way to add convenience when working with an angle grinder is to fix the tool motionless on a workbench or in a vice.

The advantage of homemade products is that at any moment the tool can be removed from the device for its intended purpose. The shaft of the grinder is brought out into the hole of the workbench, a chuck for milling heads is put on it - and you can process wood that is not too hard.
