Without corner grinding machine- grinders - cannot be used either in the garage or in a private yard. The unit allows you to cut a metal profile, clean a weld or remove rust from the surface of workpieces and parts; it has a low price and incredible ease of use. The grinder also has disadvantages, one of which is the unstable quality of the cut and the danger of skewing the cutting disc during use. You can eliminate annoying shortcomings by making a special frame with your own hands, which will turn hand tool to the present cutting machine. This will increase the speed of work and achieve accuracy that can only be obtained with industrially manufactured equipment.
Scope of application of cutting machines
Cut-off disk machines widely used in metalworking, mechanical engineering, woodworking and furniture industries. The units have found their application in household: They are used as a handy tool to perform various jobs in the workshop and garage. The cutting machine is convenient to use to solve a number of problems:
The advantages of disc cutting machines include convenience and ease of use, high cutting speed and accuracy, and the ability to replace the cutting disc in a matter of minutes.
Due to their relatively low cost, universal units have a quick payback period, so they are profitable to use in small industries and small workshops.
In the household, a cutting machine is used irregularly, so buying a factory-made tool is irrational. It is better to make a special stand for an angle grinder. This will increase the versatility of the grinder, turning it into a small-sized cutting machine.
Types of devices, their advantages and disadvantages
There are two types of designs of cutting machines, differing in the location of the grinder, which can be made at home.
The first installation is a frame with an angle grinder rigidly fixed underneath it. On work surface Only the cutting disc is visible, which fits freely into the table slot. Cutting a metal profile or sheet in this case is completely identical to cutting wooden blanks by using circular saw. Despite the very simple design, this scheme is not particularly popular. Those who have made such a device note that it is inconvenient to use due to the need to move the workpiece. This significantly reduces the accuracy of the work and makes the process unsafe. The only advantage of a machine with a bottom angle grinder is the ability to quickly cut thin metal sheets.
A cutting machine with a lower angle grinder can be used both for cutting metal and as a circular saw
The second scheme, in which the part remains stationary and moves itself cutting wheel, more convenient. The so-called pendulum saw, placed above the tabletop, allows you to cut the workpiece exactly at the required angle, while making it possible to make required quantity parts of the same type. Due to the location of the grinder on top, cutting workpieces does not require effort, and operation of the unit becomes simple and safe. The undoubted advantages of the design include the ability to quickly dismantle the grinder for traditional use. As for the disadvantages of this method, the weak link can be considered the hinge joint, which complicates the design of the machine.
A machine for cutting metal with an upper angle grinder has a more convenient design and makes it possible to cut workpieces at the desired angle
The device of a pendulum saw from a grinder
A pendulum saw made from an angle grinder is available for assembly at home and does not require expensive materials or special qualifications. The cutting machine has a simple design and consists of several components:
- bed;
- pendulum;
- mount for angle grinder.
The bed is steel frame, welded from profile pipes, with a platform made of sheet metal thickness of at least 3 mm. A bracket is attached to this plate, on which the pendulum saw hinge is mounted, as well as a stop for holding the workpiece. By the way, there can be several such stops: it is convenient when one element allows you to make a perpendicular cut, and the other makes it possible to cut the material at the required angle. The most perfect stop is a rotary device with a protractor, with the help of which any angle between the part and the cutting disc is set. Important detail: where the saw touches the platform in the tabletop, a cut is made, its width should be equal to twice the thickness of the cutting wheel, and its length should correspond to the diameter.
The standard design consists of a frame, a pendulum and a mount for an angle grinder
The pendulum of the cutting machine is a T-shaped part made of a rectangular metal profile. On one side, this unit is attached with a movable connection to the frame bracket, and on the other, a mount for an angle grinder is attached to it. The mobility of the pendulum saw hinge is provided by rolling bearings or bushings, and the return of the tool to its original position is provided by a flexible element (rubber band or spring).
The angle grinder mount is a console with one or two brackets connected to the pendulum. The angle grinder is attached to one of them with bolts. For this purpose, threaded holes are provided in the gearbox housing for attaching the handle. The second bracket is a regular clamp (stepladder) that holds the cutting tool by the body.
The ease of operation of the equipment can be significantly increased by connecting the angle grinder to a foot switch/pedal. Of course, in this case, the starting lever of the angle grinder is brought into the working position and fixed with a special button.
Required tools and materials
When starting to manufacture a cutting machine, you should understand that the accuracy of its operation is directly related to the stability of the structure. Therefore, the choice of a material of a certain thickness is dictated not so much by the requirements for the strength of the body, but by the need for its rigidity.
Before you start working, you need to prepare:
- square profile pipe (25x25x2.5 mm);
- profile pipe “rectangle” (40x20x2.5 mm);
- sheet metal thick 4–5 mm;
- ball bearings No. 202, 203 or 204 – 2 pcs.;
- calibrated rod with a thickness equal to the diameter of the hole in the inner race of the bearing (up to 100 mm);
- rod with a diameter of 8–10 mm;
- metal tire (20x4 mm);
- bolts and nuts with M8 or M thread.
Tools you will need:
- Angle Grinder;
- drill or drilling machine, set of drills;
- a set of dies for cutting metric threads;
- open-end wrenches;
- welding machine.
The presence of electric welding is desirable, but not necessary - all connections can be made on threaded connections. However, it should be understood that this method reduces the reliability and strength of the structure.
To make a machine, it is better to choose an angle grinder from a well-known manufacturer.
The main component of the cutting machine is the angle grinder. It is not recommended to use a “small” grinder designed for cutting discs with a diameter of up to 125 mm and a power of up to 500–600 W. Remember that the larger the diameter of the cutting wheel, the more versatile and reliable the machine will be.
The careful selection of power tools is also due to the wide variety of angle grinder designs available on the market. Since such equipment is not unified, the cutting machine is built according to a certain model and angle grinder size. If the equipment is unreliable, then if it fails, it will be difficult to install another angle grinder in its place without the need to rework the mounts and pendulum. That is why it is better to choose products from trusted manufacturers - Makita, Bosch and so on.
Making a cutting machine with your own hands
Preparatory stage
Work on a cutting machine begins with design. It is impossible to give the exact dimensions of the device, since the design depends on the model and size of the specific angle grinder. Nevertheless, from the presented drawings you can get an idea of the dimensions and structure of the equipment.
The design sketch begins with a drawing of the body. You may not need a frame, but a separate platform that can be attached to mechanic's workbench. In any case, determine the dimensions of the device and the location of the main components on the body. Next, the angle grinder and the center distances of the mounting holes on the gearbox housing are measured. Based on these indicators, a drawing is drawn up for attaching the angle grinder to the pendulum. After this, the rotary unit itself is designed. The shorter the distance from the hinge joint to the cutting wheel, the stiffer and more accurate the machine will be. In other words, the length of the pendulum should be as short as possible.
On last stage Designers calculate how much and what kind of material will be needed.

Drawing of a pendulum type cutting machine. The dimensions of the base are indicated on the left. On the right are the design features of the pendulum.
Step-by-step instruction
- In accordance with the drawing, blanks of the future machine are cut. For the frame and pendulum, profile pipes are used, and for cantilever mounting, a metal profile, a metal tire and a steel rod are used. If the design provides for a load-bearing platform, then sheet steel 4–5 mm thick is cut to size.
- To the pendulum lever, which is a segment profile pipe, weld the transverse axis (shaft) for the hinge connection. In this case, it is important to ensure that the shaft is attached to the pendulum perpendicularly.
After cutting the material, a shaft is welded to the pendulum arm
- A U-shaped bracket is bent from a steel tire, holes are drilled in its sides for bolts, with which the gearbox housing of the angle grinder is secured.
To attach to the threaded holes on the angle grinder gearbox housing you will need a U-shaped bracket
- A U-shaped clamp (ladder) that goes around the angle grinder is made from a steel bar and clamping bar for fixing the tool body to the pendulum. The latter represents metal plate length 15–20 mm exceeding the width of the clamp. The threaded ends of the stepladder fit freely into the holes at the edges of the pressure plate, and fixation is carried out with nuts with suitable threads.
- Trying on a U-shaped bracket and clamp for an angle grinder, welding or threaded connection mount these parts on the console.
This is what the console for attaching the angle grinder to the pendulum arm looks like, complete with a U-shaped bracket and clamp
- The bearings that will ensure the rotation of the pendulum are pressed into the supports. As the latter, you can use either ready-made factory bearing units or sections of steel pipe (15–20 mm) with a diameter equal to the outer race of the bearing.
- Bearing units are pressed onto the shaft from both sides. It is important that the connection is tight - this will eliminate unwanted longitudinal and transverse displacements. If the resulting connection is weakened for some reason, you can use a proven method - tin the axle with a soldering iron, applying thin layer tin (you will need soldering acid as a flux).
- At a distance of 50–60 mm from the edge of the platform, the pendulum assembly with support units is welded. At the same time, it is important not to overheat the bearings, so these parts are wrapped in a wet rag or constantly watered with water to cool.
The pendulum arm assembly with bearing units is welded to the platform at a distance of 50–60 mm from the edge
- A console with an installed clamp and a U-shaped angle grinder mount is welded onto the pendulum arm. The position of the grinder is chosen based on personal preferences. There are different opinions on how to attach the angle grinder (“from yourself” or “towards you”). Professional mechanics work with the tool, orienting the sheaf of sparks towards themselves, arguing that if the grinder falls out of their hands for any reason, the tool will fly off in the opposite direction. Hobbyists most often work with medium or small sanders, so they prefer to have the disk rotate “pull”, as this allows for control of the cut and prevents damage to clothing. When securing the tool, be sure to place it correctly protective cover- it must protect the worker in the event of a disk rupture.
- An angle grinder is attached to the assembled machine. Based on the weight of the tool, select and install return spring. To do this, hinges are welded to the frame and pendulum or holes with a diameter of up to 5 mm are drilled.
In order not to damage the plastic body of the angle grinder, strips of rubber are laid between it and the brackets
- Perform a test run of the grinder. First, check the operation of the machine in idle mode. At the same time, pay attention to vibrations and play in the working parts of the equipment, which are eliminated if necessary.
- Using a cutting wheel of maximum thickness, a groove is cut in the machine platform for the cutting disc. If necessary, the grinder is removed and the slot is expanded to the desired size.
This is what an improved stop with a clamping device looks like
At the last stage, workpiece stops are attached to the platform. Most often, two strips are provided (for cutting at an angle of 45 and 90 degrees), fixing them with a welded or threaded connection.
Often, devices for holding the workpiece are equipped measuring instrument. By attaching a metal ruler to the stop bar with a reference point from the grinder disk, you can quickly and accurately cut the part to the required length. Also, if desired, you can install protractors, vices and clamps various designs. Such additional details allow you to make, for example, a full cut or groove in a workpiece at any angle, free your hands, and so on.
Don’t forget to paint the fixture after all finishing work has been completed. Even a thin layer of enamel will protect the equipment from rust and make it appearance more aesthetic.

Safety precautions
While working on the cutting machine (as well as during its operation in the future), safety precautions should be strictly observed. Be sure to use a protective mask or goggles, and position the angle grinder in such a way that the sheaf of sparks is directed “away from you.” The high fire hazard of the equipment requires work to be carried out in a ventilated area and away from fuels and lubricants. During welding activities, you should also use a protective mask, thick leather gloves, closed shoes and protective overalls.
When working with a cutting machine, do not try to speed up the process by applying excessive pressure on the tool. IN best case scenario such a rush can result in a torn disk and a jammed clamping nut.
When using a welding machine, ensure good grounding and avoid operating equipment with exposed cable sections. Remember that welding open area prohibited in rainy weather. As for the operation of the cutting machine, when arranging a button to turn it on, protect yourself by installing a simple decoupling with a 12-volt power relay. To do this, you can make a pedal with any non-latching switch (for example, a doorbell button) and use any solid-state relay designed for switching currents of at least 10A. A battery or accumulator with a voltage of 5 to 24 V is used as a power source.
The cutting machine from the grinder is handy tool, which can be easily made if you have skills in working with electric welding and plumbing tools. Pendulum made in just one day Circular Saw will save time in the future and allow you to perform plumbing and welding work accurately and accurately.
The grinder is a useful and versatile tool. It is suitable for cutting metal, stone, tiles and grinding surfaces. However, sometimes there are situations in which a stationary machine is more suitable for this type of work. It’s good that using certain tools for an angle grinder, it can be turned into a cutting machine.
Finding a ready-made machine that meets your needs in stores is not difficult. However, the likelihood of finding a design that firmly fixes the angle grinder and does not dangle during operation is not great, since they are all made of duralumin. For this reason, many people prefer to make various accessories for an angle grinder with their own hands.
When performing construction and installation work A large number of different tools are used. The most commonly used grinder is the grinder. The main task for which it is used: metal cutting; processing of building materials.
If you also use attachments with this tool, you can expand the number of options for its use. In particular, using this tool with attachments, you can perform high-quality grinding blank bases. They will be cleared of foreign inclusions. Attachments for grinders can be purchased at the store. But if you do not want to pay money, then you can make them yourself.
In some cases, this tool is used as a wall chaser. With his help grooves are created for laying pipes and electrical wires. To use an angle grinder in this capacity, you will have to perform some manipulations and increase standard width protective casing. In addition, you will need to make a support plate.
This tool can be used with one disk or several at once. If the grinder is used with two disks, then it is necessary to make some changes to the attachment point of this tool. After this, the grinder can be used in standard mode.
It often happens that during repair work and there is a need to clean the base of parts that are difficult to access. In such cases, craftsmen most often resort to using a homemade device for an angle grinder in the form of a special attachment, thanks to which the disc small size can be carried beyond the dimensions of the angle grinder.
In this case, the rotation will be transmitted using special belt drive from the main drive. Using this design, materials cannot be cut. However, scale can be removed from the surface of materials without any problems. It often occurs on the surface of welds.
Currently, the market offers a large number of attachments for tools such as an angle grinder. Their use makes it possible to significantly expand application options this tool. If we talk about the most commonly used attachments for grinders, we can highlight the following:
- a device for sanding the base and removing the paint layer from the surfaces of materials;
- beds;
- protractors.
Materials and tools to make attachments for an angle grinder
When the need arises to use an angle grinder for specific tasks, in this case many craftsmen opt for ready-made attachments. They can be purchased without any problems at a hardware store.
The cost of the devices is not very high, so everyone can afford them. There are also no difficulties in finding these attachments. However, despite all this, many people still decide to make attachments for an angle grinder with their own hands.
If you decide to make attachments for this tool yourself, then before you begin, you need to prepare the following tools:
- An electric drill, it is advisable to purchase a set of drills in addition to it;
- It is advisable to choose discs with a diameter of 125 mm.
- Wooden bars.
- Metal corner.
- Duralumin steel plate.
- Self-tapping screws.
Work technology
Before starting work, you need to cut a plate out of metal. After this you need to make an angle out of it. To achieve your plan, you must first do triangle shaped cutout in the workpiece shelf. And when this is done, the workpiece must be bent at a right angle.
Further, the design of the plate should drill six holes. The diameter of each of them should be 4 mm. Subsequently, it is in these holes that the self-tapping screws will be installed. With their help it will be possible to fix the handle, corners and timber. All holes must have special recesses for screw heads.
To securely fasten the beam handle, a few self-tapping screws are enough. The fasteners used during this work must have dimensions of 3x35 mm. This will result in an L-shaped part.
After this, all the elements together with the plate are assembled into a single structure. The created tool fixture must be secured using 3x20 mm self-tapping screws.
So, the basis of the future structure has been made. Next, you will need to perform installation of metal corners. You should have several of these items available. They must have the following dimensions:
- 75x30x55 mm;
- 45x60x60 mm.
Please note that the first corner must be extended to 60 degrees. If this is not done, then you will not be able to achieve your main goal - to fix the manufactured structure on the grinder. When the installation of the metal corners is completed, the tool itself is attached directly to them.
To connect the tool and structural elements, use a separate handle on one side, and bolts with nuts, on the other side. The latter are necessary so that during work the screw of the structure does not unscrew.
If desired, you can refuse to install the nut on the handle, since it will be held by the hand of the master during work. At this point, the work on creating a cutting structure can be considered complete.
How to make a frame for an angle grinder
Grinders are often used together with a stand. They are used mainly for the master to perform certain works for cutting materials and workpieces with less physical effort.
It is obvious to everyone that it is extremely difficult to hold a heavy instrument for several hours. Therefore, to make their work easier when performing an operation, many craftsmen manufacture special devices , which are called beds. When an angle grinder is equipped with such a device, cutting work can be done using only one hand.
To make a frame, you first need do wooden box . You can get by with only one side on which the tool will be attached. All other walls can be removed, and legs of a special design can be attached instead.
But in order to achieve the effectiveness of using an angle grinder with such a device, it is necessary to make some changes to its design.
The first step is to do dismantling the casing of the angle grinder. After this, you need to put a disk on the instrument. When this action is completed, it must be pressed against the side wall of the device.
It is necessary to mark where the gap was made for the movement of the nozzle or disk. Its width should not be too large, otherwise foreign objects may get inside the structure during work.
If desired, the gap can be increased. The need for this arises in cases where it is necessary to replace the nozzles without completely disassembling the entire structure. Samples of wooden blocks can be used as support elements. After this, you can begin cutting workpieces.
Protractor for grinder
When carrying out construction and installation work, an important device for an angle grinder is a protractor. It is especially indispensable when work is carried out on processing or cutting metal profiles.
By using such devices, you can easily calculate cutting angles blanks And this has a positive effect on the speed and quality of work performed. In addition, this device is suitable for cutting metal profiles.
- This type of design is widely in demand when working on wall and floor tiles.
- They are also used for cutting and processing flooring and baseboards.
By making a protractor for an angle grinder with your own hands, you will no longer need to purchase special tools, which are often expensive and large in size. For industrial use a homemade protractor is not suitable, but for use at home it will be an excellent replacement for store-bought tools.
The operating principle of a homemade protractor design
The first thing to do is install guide angle, equipped with a special overlay, on the tile. A similar pad is used to prevent the workpiece being fastened from slipping. Therefore, thanks to it, displacement of the element will be eliminated.
Then you need to press the workpiece tightly against the shelves of the corner. After this, the user must set the cutting angle he needs.
Next, you can proceed to cutting the material. When performing this action, it is necessary to take into account that when cutting it is necessary to press lightly on the disc. There is no need to make any serious physical effort.
A homemade protractor for an angle grinder has a design consisting of the following elements:
- Corner.
- Loops.
- Bolt used for fixation.
Note that making such elements with your own hands is quite difficult. Therefore, if you are unsure that you can cope with such a task, then it is better buy in store ready-made models of protractors.
The grinder is a fairly popular tool among builders and repair specialists. It can be used to cut various materials And process workpieces and parts. However, sometimes specific operations are required. Therefore, experts purchase special attachments for the grinder. They can be found in stores without any problems.
The use of such devices allows you to expand the number of options for using this tool. However, it is not always necessary to buy them in construction stores. If you wish, you can make them yourself. To do this you just need to have free time and know how to properly make attachments for an angle grinder.
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.
Sand the weld seams using a grinder attachment.
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 onto the tubes masking tape 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 bearings suitable for its inner diameter. 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 stand 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 pieces of square 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.
At the next stage, you can attach the angle grinder to the finished structure and check again what came out of it.
A ready-made 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 the abrasive wheel mounted 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 you can correct the situation 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, this is easy to do: insert a smaller tube from the back of the rod 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
Another version of the device for the grinder, with which you can cut metal blanks, 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 larger profiles than in the figures 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 It 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. Since this process is 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.
Bulgarian is electric tool, with which you can carry out a large volume of construction work. She cuts metal parts, stone and other hard materials. It can be used to clean and polish surfaces, and cut ceramic tiles to size. This tool is indispensable for installation, construction and repair work. Use it at home and in the workplace.
Safety regulations
The grinder is a dangerous object with enormous momentum. If you do not follow the instructions for use, you can be seriously injured. Before starting work and making a homemade stand for an angle grinder, be sure to read the safety rules.
1. When cutting hard materials from under abrasive wheel Various particles of metal or stone and sharp fragments fly out. The first reliable remedy for debris flying into the master’s face is type. There are cases where the circle itself is broken. Shards can hit the glasses and break them, so glasses should be reinforced, with a protective mesh. Don't be stingy, it's your health.
2. The grinder must have a screen surrounding the knives. Some workers, when putting on a large diameter circle, remove the casing that interferes with movement. Also, when making it yourself, they can get rid of it altogether. Under no circumstances should this be done. It is placed without fail and in such a way that the operator is behind it. Thus, the fragments are knocked off the casing and fly in the opposite direction.
Stand for grinder
When working with this tool, many craftsmen have to perform monotonous, identical cuts. Holding it in your hand, it is very difficult to achieve evenness of the strip. Strong rotations and vibration do not allow a person to hold the product exactly in one position; the hand will definitely move. To prevent this from happening, buy a stand for the grinder.
But under strong constant loads and vibrations, the parts of the stand become loose and crack. Yes, and it is mainly designed to work with a circle of maximum 125 mm. The big one won't fit there. If you want a stand for an angle grinder that is strong and reliable, then the best option will do it with your own hands. Self-production will add confidence in the quality of the fasteners, the master will work calmly.
Small device for home use
This product is manufactured for home use only, for minor works. It is made from plywood and wooden blocks. The tool itself is installed stationary and does not move. Take two sheets of plywood. A grinder is secured to the bottom square with clamps and a beam in the form of a stand is screwed on.
Second part on furniture hinges placed on top. A slit is cut for. The advantage of this arrangement is that the master does not hold the tool in his hands. Also, the circle is partially visible and cannot fly out, causing injury to the operator. Such an easy-to-use device for cutting small metal corners is suitable, aluminum profile, ceramic tiles.
Welded metal structure
When making this model, you need to have a drawing of a stand for an angle grinder of your size.
Work is carried out from a metal profile and tubes using welding machine. The platform for the stand must be heavy and capable of withstanding high-power vibrations. Next, the upper part is made, to which the tool itself is attached along with the casing. The bolted structure is installed to a welded corner on two metal legs.
In order for the angle grinder stand to move smoothly, the top and bottom panels are connected by a strong spring, for which holes are drilled. A guide angle is welded onto the platform at right angles to the circle.
Pendulum stand
What’s good about a pendulum-shaped stand for an angle grinder is that it simplifies the sawing process. Due to the support on the table and the system of this design, you can perform work of varying complexity and trim materials of any density. With such a device, you do not need to apply much effort; the pressure is carried out by the mass of the tool itself.
For the manufacture of this option stands will need a spring, two hinges, a metal profile, corners and a welding machine. It is also advisable to have a strong iron table on which the entire structure can be installed. Having skills in such work, the master will quickly make such a pendulum. It is much easier to work if the handle is long and comfortable. The fingers are at a safe distance. No bending required. Sparks and debris fly in the opposite direction. And having a free approach to the table, you can perform work with large materials and products. It is convenient and allows you to perform a variety of processes.
When choosing a rack that suits you in all respects, do not forget about safety precautions. Then work will bring only joy.
The grinder is a useful and versatile tool. It is suitable for cutting metal, stone, tiles and grinding surfaces. However, sometimes there are situations in which a stationary machine is more suitable for this type of work. It’s good that using certain accessories for an angle grinder, you can turn it, for example, into a cutting machine!
Grinder machines
Finding a ready-made machine that meets your needs in stores is not difficult. However, the likelihood of finding a design that rigidly fixes the angle grinder and does not move during operation is not great, since they are all made of duralumin. For this reason, people who have machines improve or remodel them in every possible way. But there are many serious obstacles here - the materials of the machine are difficult to weld, or, for example, the design does not take into account points that are important for you - for example, an accurate ruler or a more elastic spring. Remaking someone else's is more difficult task than making your own!
Purchased version of the grinder holder
Making your own simple device for an angle grinder can be done with minimal costs and within a few hours! In fact, the structure will be a long metal pipe, which is both a frame and a handle. At one end, a transverse metal strip is welded, which has two holes for fastening the grinder.

From the same edge, the pipe is attached to a small piece of angle on the movable shaft. The corner itself can be attached to the desktop or to the floor! A spring should be fixed on the opposite side of the fastener, returning the entire structure to its original position.

That's all - the manufacture of the machine is completed, all that remains is to properly secure the angle grinder. Naturally, this option should be used for simple work, and if precise and complex procedures are required, then the design should be more complex.
Making a cutting machine from a grinder for precision work!
Devices for grinders such as cutting machines are made using the following materials and tools: steel angle, profile pipe, metal sheet under a platform (you can use chipboard), a welding machine, a channel, a drill, a shaft, several bearings, a pipe with a small diameter, a spring, a relay and a pedal. Welding, in principle, can be replaced with strong bolts - here you will have to use a drill.
It is worth noting that with this implementation of the machine, it can be easily disassembled if such a need arises.

Parts and fasteners
We start making the machine from the frame. Each grinder will require an individual design, since each manufacturer produces grinders of its own design - in some you will have to remove the handle, and in others you will need to invent a stand for the entire grinder as a whole! In addition, for different diameters drives require different frames.
Frame
The simplest frame consists of two frames and a common axis. The lower frame must be fixed on top of a metal or chipboard platform. For a large grinder, it is better to use metal. It is necessary to ensure rotation of the upper frame on which the angle grinder is attached relative to the lower frame in vertical plane, like a pendulum. To fix the starting position, you will have to use a spring. A fastener should be welded onto the lower frame, which includes a clamping angle and a movable clamp.

Ruler - for this particular case, you can use a movable ruler with a limiter, which is welded onto the tube. It adjusts the accuracy of the size, after which it is secured using an end screw!
Electronics. To increase the usability of your machine, you need to provide such things as a start pedal or button (switching using a 12 V low-voltage relay). Using this pedal, voltage will be supplied to the grinder.

With the help of such a simple device for an angle grinder, we can free our hands and at the same time make an accurate, even cut without using a vice, and saving time on measurements also plays an important role. With this design it can be replaced cut-off saw on metal, and if suddenly necessary, the grinder can be easily dismantled.
