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 cutting machine, with the help of which it becomes possible to 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 from the corner grinding machine(angle grinder) to make a cutting machine, you can look at various drawings on the Internet. 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 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 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 step is to do 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 angles 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.
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 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 the 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
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 the attachment of the device to the lever, you can use clamps, having previously placed them between the angle grinder body and the pipe, for example, wooden block.
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 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.
The angle grinder has become widespread due to its variety of functionality. This type The tool is universal, as it is capable of performing work such as cutting, grinding, and cleaning. The functionality of this tool can be expanded, but this will require some accessories. These are devices for an angle grinder that will allow you to make a tool out of milling machine, wall chaser, cutting machine and others.
To make any device for an angle grinder with your own hands, you first need to decide what materials are available for manufacturing. You should also decide what exactly should be made: a milling or cutting machine, a wall chaser or a dust collector for working with tools indoors.
To make such devices, there is usually no need to buy additional materials or parts, since absolutely any simple materials at hand will do. To make some devices, such as a dust collector casing, it is enough to use a plastic canister of oil or brake fluid. Using a tin can, you can construct a hand mill for making coarse flour.
It is important to know! When starting work, decide what exactly you want to get from the grinder in the end. After all, such a design must be necessary, and of course reliable.
Stand for grinder
Making such a device for an angle grinder, like a stand, with your own hands is not difficult. Its manufacture will allow the tool to be used for more precise sawing work. various types materials. When making a cutting machine, the following tasks must be completed:
- Reliability of tool fastening.
- Reliable fixation of the tool in the upper position.
- Ensuring minimal deviations from the cutting plane.
Threaded connections are well suited for securely fastening the grinder. Additionally, you should also worry about safety, so the tool should be equipped with a homemade casing.
For grinders for circles with a diameter of 115 mm to 150 mm, they can be attached to the stand using clamps. Tools for a circle diameter over 150 mm must be securely fastened not only to the moving console, but also to the work table or bed. To reduce vibrations and increase cutting accuracy, it is recommended to firmly fix the frame to a workbench or other base. Below is another version of the stand with a fixed angle grinder.
DIY pendulum cutting machine
To manufacture such a device from a grinder as a pendulum cutting machine, it will be necessary to ensure that the moving console automatically returns to the reverse position. This is achieved by installing a special spring, rubber band or counterweight, which will automatically return the used angle grinder to its original position.
The production technology of such a machine is almost identical to the previous one. The difference lies in the addition of an auto-return mechanism for the moving part on which the angle grinder is attached. This makes human work easier.
Milling cutter from a grinder
The grinder can also be used as a router. It is important to take into account the fact that the tool must be able to be removed from a homemade device. To make such a design, you will need to secure the angle grinder under the table (or workbench) you have made, and bring the tool shaft into the hole in the workbench using an adapter with a collet clamp for cutters. The manufactured tool can be used various works on wood, depending on the cutter used.
Circular grinder
You can make it from a grinder. To do this, you will need to make a reliable frame or base to which the tool will be attached.
It is important to know! Woodworking discs should only be used of proper quality. The absence of at least one tooth prohibits the use of a disk for cutting wood.
If during the manufacture of a cutting machine cutting tool should be located above the work table, then when designing a milling unit and a circular saw, the opposite is true. The grinder should be placed under the tabletop, from which the certain part disk. Additionally, you can screw a ruler to the tabletop, which will help you cut wood more accurately.
Do-it-yourself wall chaser from an angle grinder
The grinder can be used to cut cuts in the wall. They are made so that wiring, pipes and other elements can be laid in them. When working with a stock angle grinder, it is very difficult to control the immersion depth of the disc. To solve this problem, you can make a special frame.
It is important to know! Such a device for an angle grinder has important advantage, as it allows you to adjust the depth of the groove being made.
Such a frame is a sole with a stop, through which you can move the tool along the wall with uniform depth, thereby obtaining a groove of the required depth. When making this, pay attention to the protective cover and a special dust collector. You can use a bag as a dust collector, but it is more convenient to connect a hose from a vacuum cleaner. With its help, dust will be sucked out, making such work much more pleasant and dust-free.
About a homemade dust collector
A dust collector or casing for an angle grinder can be made from an old aluminum pan, pieces thin metal or plastic canister. The casing made from a pan will be more reliable, but at the same time plastic construction much easier to make.
For construction, a galvanized sheet is also suitable, which should be welded based on the dimensions of the existing tool. An important condition is the reliability of fastening such a homemade product to an angle grinder. In addition, the dust collection hole can be made with the most convenient angle of inclination, unlike purchased dust collectors.
Protractor for grinder
A protractor for an angle grinder is also called a device for cutting along guides. To make such a device, a metal profile or channel is most often used. To construct a protractor, you need to build a structure from the corners of metal, as shown in the photo below.
Now all that remains is to fix the tool to the resulting product, which will result in a full-fledged protractor, through which you can adjust the cutting depth.
In conclusion, it should be noted that the material presents only the main types of devices. In fact, an angle grinder is such a universal unit that ideas for its modernization are constantly being updated. Choose from the proposed list the devices you need and turn them into reality.
Metal is the material that the angle grinder (angle grinder) was originally designed to work with. Now it is used to cut reinforcing bars, various metal sheets, pipes of various diameters, brick, concrete, stone, tiles and other building materials. Thanks to the presence of a variety of attachments, the grinder also allows you to polish and grind the surfaces of products. Cutting metal with a grinder is one of the main, most common jobs. To reduce the likelihood of injury, it must be performed correctly, with strict adherence to general and personal safety requirements.
Bulgarian belongs to the category of relatively dangerous power tools. You can get injured from a flying disc or a tool falling out of your hands. In both cases, the danger is associated with the high speed of rotation of the device's electric motor.
To increase the efficiency of the grinder, expand it functionality, in practice they use such additional accessories:
- tripods;
- retainers.
Their use makes it possible to improve the quality of sawing metal workpieces and increase the accuracy of the process. Working conditions also improve in terms of safety, and productivity increases.
Usage additional accessories allows you to use the tool as a machine designed to perform different types works
To make the cutting process as safe as possible, working on metal with an angle grinder should follow a number of rules. They are conventionally divided into preparatory and main (working) activities.
Before cutting begins, a number of manipulations must be carried out.
If possible, the material to be sawn should first be securely fixed, for example, in a vice, in order to eliminate possible accidental movements.
Holding workpieces in your hands or between your knees is prohibited.
Correct use of the tool
- When you start sawing any part using an angle grinder, you should adhere to these rules.
- When cutting metal, you need to hold the grinder firmly, with both hands.
- The wheels can be changed only after they have completely stopped rotating and cooled down to an acceptable temperature, disconnecting the power tool from the power supply.
- Do not place the working tool on the ground or table (do not let it out of your hands). Required periodically for about 5 minutes stop to rest
- , and to keep the disk cool.
- It is necessary to constantly monitor the condition of the cutting wheel, preventing it from being pinched by the edges of the workpiece being cut.
- Do not leave the tool plugged in unattended. Use discs only suitable size
- specified in the operating instructions for the device used. Get the job done better on flat surface
- so that the body position is stable.
- Make sure that the power cord is kept away from the rotating circle, sharp edges, and objects heated above 100 degrees.
- Movements not directly related to cutting should only be performed with the power tool turned off.
You need to position yourself on the side or behind the tool, doing the work with your own hands so that parts of the body are not in the cutting plane.
When cutting metal with a grinder is finished, you should wait until the disk stops completely and disconnect the power cord of the tool from the network. Afterwards, it is recommended to ensure that there are no signs of fire. When cutting materials, a right-handed person should correctly hold the handle of the device in the area of the on/off button with his right hand. The left hand is placed on the handle screwed into the body of the power tool from above.
As for the question of which direction—toward or away from you—the disk of a switched-on angle grinder should rotate, there is no definite answer.
The operating instructions indicate that the first option is correct. This is due to the fact that the resulting sparks fly away in the direction opposite to the operator, without causing harm. Also, fragments of the circle will fly in that direction if it breaks into pieces.
But if the rotating disk jams towards itself, the tool will fly off towards the worker. For this reason, many specialists prefer to cut metal so that the circle rotates “from itself”. A power tool torn out of your hands will fly in the opposite direction. This reduces the likelihood of injury, and clothing, shoes and gloves will protect the user from flying sparks.
Cutting sheet metal with a grinder
- To cut metal of different types and thicknesses, use appropriate cutting wheels of various thicknesses and diameters. The algorithm for sawing sheets is as follows.
- To cut using a grinder, sheet metal is first laid on a flat surface.
- Mark with chalk (marker) the exact dimensions of the cut out fragments on the surface of the sheet.
Sawing is carried out along the marked lines, without changing the angle of the initial inclination of the disk to the working surface, so that it does not jam and break the power tool. If you do not have the skills to saw sheet metal with a grinder, it is recommended that you first practice on delicate material
- this will give you the opportunity to feel the operation of the instrument.
It must be taken into account that the lower proximal segment of the disc cuts metal more effectively.
- When cutting a sheet of metal, the following recommendations should be taken into account to obtain a high-quality result. To improve cooling, a sawing area is required water
- , which will also increase the life of the circle.
- You should start cutting metal only when the disk is rotating: you cannot turn on the tool if the stationary circle is in contact with the surface of the workpiece. To saw tin (thin sheet metal) or cut out different geometric figures , it is more convenient to use small ones, worked out circles
- (“bits”)
- You should not press the angle grinder with significant force: cutting should take place almost exclusively under the angle grinder’s own weight.
If sawing the sheet occurs slowly, you should change the working nozzle. Excessive load on the angle grinder when cutting metal will lead to overheating or jamming of the rotating wheel.
Cutting a round hole in metal using an angle grinder
In practice, it is often necessary to cut a circle in metal, and the only tool available is an angle grinder. But it is quite enough for this purpose. The algorithm of actions is as follows.
- Draw a circle with a compass on the surface of the metal or on a pre-made paper (cardboard) template with chalk or a marker.
- Holding the grinder at an angle to the surface of the sheet, make a preliminary marking cut of the metal along the marked contour, making short movements with the disk (sawing in small sections).
- Then, moving the nozzle in the same way, deepen the slot until it is completely cut out.
Need to cut along the outer contour of the circle, so as not to reduce the size of the circle. If its diameter is small, then they cut by touching the metal with a disk point by point (without longitudinal movement of the nozzle). The round hole will have an oblique cut, as well as some minor flaws (they depend on the skill of the worker). Afterwards it is processed, if necessary.
The whole process of cutting a round hole in sheet metal using a special device is shown in the video:
Features of working with thick metal, copper, cast iron, aluminum
When you need to cut thick metal into individual fragments, it is recommended to additionally perform the following actions:
- constantly cool the area of contact between the metal and the disk using cold water due to strong heating of the slot site;
- make all cuts only in a straight line;
- different curved contours should be cut out in separate straight sections of short length, removing unnecessary parts;
- You need to completely saw the workpiece in several approaches, deepening the slot with each subsequent one;
- if you need to cut corners, I-beams, channels, rails, then each of their structural parts is sawed separately.
Cutting cast iron, stainless steel, as well as non-ferrous metals, such as aluminum and copper, is carried out using special circles designed to work with these materials. All the necessary information about the discs is contained in the markings of these products, printed on their sides. In this case, the circles differ in the composition of the fillers:
- in some, the additive is a super-strong material that can cut alloy steel;
- others use mild binders.
Cutting stainless steel with conventional metal cutting discs is prohibited, because they contain substances that lead to accelerated corrosion of the cut site. Aluminum and copper are very viscous non-ferrous metals. They are sawed using a grinder, pouring kerosene the slot formed by the disk. In this case, it is necessary to comply with fire safety rules.
Cutting pipes from different metals– This is a popular operation when carrying out repair and construction work. Products have to be cut off when installing sewer and heating systems and water lines. In this regard, the grinder copes well with various tasks. Discs for work are selected according to the material from which the pipe is made.
Using an angle grinder makes it possible to:
- sawing pipes at different angles, for example 45 and 90 degrees;
- cut products large diameter;
- cut profile (rectangular or square) pipes smoothly;
- perform longitudinal cutting of tubular blanks;
- sawing cast iron pipes;
- cut thin-walled tubes.
If you need to cut a large diameter pipe, then using a grinder allows you to complete this work without significant financial costs. But at the same time, labor productivity is low, and the risks are considerable. When long pipes lie on supports, only saw off hanging parts. If you cut in the center, the cutting edges will jam the cutting wheel, which will lead to jamming of the tool and possible injury.
Specialists not only cut pipes from different materials at the required angles, but also cut out holes of the required shapes in them. Work with profile and round workpieces is carried out in a similar way, with mandatory observance of safety regulations.
Sawing pipes at different angles
Cut at 45 and 90 degree angles round and profile pipes necessary when laying various communications. In any case, it is necessary to saw off the pipe evenly so that the elements that need to be connected are connected to each other as tightly as possible.
Res at an angle of 45 degrees cylindrical pipes are carried out as follows:
- take an ordinary square sheet of paper;
- fold it exactly diagonally;
- This template is used to wrap the pipe;
- use chalk or other marking device to mark the future cutting line;
- remove the template;
- clamp the workpiece in a vice;
- cut off the marked piece of pipe.
When applying the template, either of the two short sides of this triangle should be parallel to the central axis of the pipe.
When to cut at an angle of 90 degrees, the pipes are simply wrapped in a circle (cylindrical) or around the perimeter (profile) with a sheet of paper. After this, mark the cutting line. You can also mark a profile pipe very simply using a regular square.
If it is necessary to cut a significant number of profile pipes at an angle of 45 and 90 degrees, appropriate templates are made from of this material, only with a larger cross-section.
This allows you to perform the required measurements only once. In this case, a construction square or a protractor is used for initial marking. When the template is made, the cut pieces are inserted inside it, marking the cut lines. Then sawing is done.
Templates are also made for other angle sizes. This method increases labor efficiency.
Features of cutting cast iron and thin-walled pipes Cast iron is brittle material . To saw cast iron pipe
- grinder, act in the following sequence:
- mark the cutting line;
- place a wooden block under the pipe, which will serve as a support for it;
- make a cut along the contour several millimeters deep;
- insert a chisel into the recess made;
the instruction is hit hard and sharply with a hammer.
After the impact, the pipe will split along the cut line. Its edges will be quite smooth. If necessary, they are further processed. To perform longitudinal sawing of a pipe, it is also important precise marking . For its application it is used various devices
, for example, construction thread (“beat”). The entire sawing process should be carried out carefully, slowly, so as not to stray from the marked line.
Thin-walled pipes are one of the varieties of this type of product. They are often made of non-ferrous metals: copper or aluminum. Cutting them is a difficult task. In this case, you should use grinder wheels that match the material of the workpiece.
Sawing thin-walled tubes must be done very carefully, because they can easily become deformed even when a slight load is applied.
To reduce the likelihood of bending of the cut part, various bulk fillers are poured inside it, for example, ordinary purified sand.
Cutting corrugated sheets and metal tiles Quite often in practice one has to deal with the need to trim profile sheet or metal tiles. These materials are made of steel, which is coated with zinc and polymer. protective layers
, color. People speak out about the possibility of using a grinder for cutting them. The installation instructions say that the corrugated sheet cannot be sawed using an angle grinder. To do this you need to use other tools. But they need to be purchased, which is not always justified by the volume of work to be done, and also requires additional financial investments. When there is no tool other than an angle grinder, before sawing with a grinder, you should know the possible Negative consequences.
- If you cut metal tiles or corrugated sheets with an angle grinder, then protective covering in the cut area and a little near it will be destroyed, and the cut edge will begin to rust.
- The material is removed from warranty.
- Flying sparks can damage not only appearance the rest of the sheet (sear the paint), but also damage the polymer coating.
- The edge of the cut may turn out torn.
All considered negative consequences can be minimized if you cut corrugated sheets or metal tiles with a grinder, following the following recommendations:
- carry out all work immediately before installation;
- treat cuts with anti-corrosion compounds;
- cover the cut edges with primer and paint;
- use discs for metal minimum thickness(up to 1 mm);
- To keep the edges neat, you need to cut quite quickly;
- Carefully sand the torn edges.
Before sawing, as usual, carry out marking sheets.
If you need to cut a square, do this:
- draw it on the surface of the sheet;
- cut through the material along the marked contour with a grinder;
- At the end, carefully cut out each corner.
Circles or other shapes are cut out using the same pattern.
Using a grinder for cutting metal tiles and corrugated sheets makes the job easier. It becomes more convenient to perform it, because you can adjust the sheets to size directly on the roof.
In order for metal tiles or corrugated sheets to remain under warranty, you should measure the object and order factory cutting of the sheets. You can also try to choose a material with dimensions such that trimming is not required.
Cutting metal with a grinder is cheap, practically accessible and quite effective method sawing it. In this case, appropriate discs without defects should be used for each material. Not only the quality of the result obtained will depend on this, but also own health. When sawing metal, it is imperative to follow safety rules and use tools personal protection. You should always remember that when working with an angle grinder, any shortcomings or inattention can result in injury. Therefore, you need to work with concentration and caution.
Attachments for an angle grinder greatly expand its functionality; they can be installed on turbines of any size. Using simple devices, you can make a cutting unit or a machine for cutting grooves (grooves in concrete), which will ensure the quality of work at the highest level. Eliminates the need to purchase expensive professional tool, since good work can be done with homemade improvised means.
Types of devices
Adaptations for grinders exist with a wide variety of functions:
- for smooth cutting;
- for grinding;
- for cutting rods and pipes with a diameter of 50 to 125 mm;
- for stripping old layers from surfaces;
- for cleaning and grinding;
- for polishing;
- chain saw for cutting wood;
- for collecting and removing dust during work.
These devices are also called accessories. They are often purchased separately from the main unit. Some of them can be made independently from available material or old equipment.
Manufacturers
The most common and popular attachments are cutting discs. For metal, good wheels are produced by Makita and Bosch. The best diamond bits are produced by Hitachi (Japan) - such discs are universal and can successfully cut any material.
Appreciated grinding attachments from the DeWalt company from America. They differ in the material from which they are made; they can be: sponge, fabric, felt.
To work with stone and metal, special abrasive attachments are used. The highest quality specialists are considered to be products from DWT (Switzerland) and Interskol (Russia). The products of the latter company stand out due to their combination of price and quality. The above companies also produce good grinding discs that are coated with diamond.
In addition, DWT produces high-quality angle grinder attachments called cutters. They are used to remove old paint, cement, primer.
Various nozzles for turbines are very good quality Produced by the Fiolent company. Prices for attachments from this manufacturer are low. “Fiolent” appeared on the market relatively recently, but has already gained a good reputation and authority.
The Bort company from China also makes good attachments for grinders. As you know, products from Chinese manufacturers are traditionally low in price.
How to do it yourself?
Before making, for example, any machine using an angle grinder (the device is quite simple), it is recommended that you familiarize yourself with the drawings and diagrams that can be found on the Internet or in specialized literature. They will help you better understand the principle of construction of the grinders themselves, as well as how the various attachments that may be required are made. The nodes will have to be selected empirically, focusing on the actual dimensions of this particular turbine model. Such a unit can be ideal for cutting and trimming various workpieces.
There are dozens of different attachments that can be the most different sizes, therefore, the parameters of the working elements should be selected when this particular model is in front of your eyes.
Creating a machine for cutting wood
Two pieces are cut from the corner (45x45 mm). More precise dimensions should be looked at by the dimensions of the angle grinder gearbox unit. 12 mm holes are drilled in the corners (an angle grinder is screwed to them). If the factory bolts are too long, they can be trimmed later. Sometimes studs are used instead of bolted fastenings; this does not in any way affect the quality of the connection. Often the corners are welded; this type of fastening is the most reliable.
A special support for the lever is made, the unit is attached to it, for this you should select two sections of pipes so that they fit into each other with a small gap. To make the marking more accurate, it is recommended to wrap the fragments with adhesive mounting tape, draw lines with a marker. A cut is made along the line; the pipe element with a smaller diameter should be smaller in size (1.8 cm). For the internal diameter, you will need to find two bearings that are inserted into a larger pipe, then a pipe with a smaller diameter is inserted into a larger diameter pipe. The bearings are pressed on both sides.
The mount is placed in the bearing; be sure to install a lock washer in the bolt mount. After the rotating unit is prepared, a small fragment of the corner should be fixed.
Vertical mount for rotary unit made from a 50x50 mm corner, the segments must be the same size. The corners are fixed with a clamp and cut off.
Now you need to figure out how long the lever will be needed - the angle grinder will be attached to it. A similar action is carried out using selection technology, and the parameters of the turbine should be taken into account. Often, parts are first laid out on a flat plane and analyzed, then the configuration and dimensions of the product become clear. The pipe most often used is square with a size of 18x18 mm.
After precise adjustment of all elements, they can be fastened together by welding.
The pendulum assembly is easy to install on any plane. It could be wooden table, which is sheathed metal sheet. A more rigid fastening is ensured by welding two small fragments in which holes are drilled.
During installation, one of the main working points is setting an angle of 90 degrees between the plane of the disk and the supporting surface (“sole”). In this case, you should use a construction square, which is attached to the abrasive wheel (it is mounted on the angle grinder). For a craftsman, welding a fragment at an angle of 90 degrees is not difficult; it will take a little time.
You should also make sure that the workpiece is firmly secured during operation. A vice is often placed on a flat surface, which provides reliable fastening. After all operations performed, a protective coating (casing) should be made. It is recommended to take the disk size into account here. Before starting work, you should cut out an exact template of the future part from cardboard.
The protective screen can be made from two pieces of tin. An aluminum corner is attached to one of the blanks; it will allow you to securely fasten the protective screen using a cross member. Such accessories are necessary for normal operation, since the angle grinder is a tool with increased injury rates.
Small holes are made on the screen, and the prepared fragment is secured using nuts and bolts. The protective casing can be painted with oil paint, and if it is made correctly, it will serve long time and reliably protect the employee.
The base-stand for the machine is sometimes made of silicate or red brick.
Metal grinding machine
There is another option that will allow you to process metal parts. To do this, take profile pipes (2 pieces) and attach them by welding to a rectangle made of steel sheet 5 mm thick. Holes are drilled in the posts and arm, and the dimensions can only be determined empirically.
Let's consider the stages of work.
- The lever is attached.
- A spring is attached.
- Holes are drilled for bolt fasteners.
- The rod is also drilled (a 6 mm drill is suitable).
- After preparatory work The turbine can be mounted on a working plane.
The design of the device is simple. It turns out to be a portable edger. At some joints, clamp fastenings can be made, and gaps can be filled with wooden dies.
For a more reliable stop, an additional corner is screwed on. It is also permissible to attach a small angle grinder to a metal strip (5 mm thick), and it is also reasonable to use a clamp fastening.
A dust collector is most often used to remove dust during work. For an angle grinder, you can make an effective attachment from a PVC container with a volume of 2–5 liters. A frame is made on the bottle with a marker, and a rectangular hole is cut in the side. The dust collector is attached to the turbine, and an exhaust hose is mounted on the neck.
Gaps can be sealed with special thermal putty, which is used to seal wooden windows.
Exhaust device necessary: it significantly helps in the work when the grinder is used for stripping various surfaces from old paint, insulation, rust, cement mortar. You can use various attachments with metal mesh. These works are related to education large quantity dust, therefore personal protective equipment should be used.
Making a Pendulum Saw
The pendulum saw is made as follows.
For rigid fastening, brackets are suitable, with which you can fix the angle grinder. To make the device, you will need five identical pieces of metal reinforcement. They are welded to form a bracket mount. A clamp-type mount is created that will fix the handle of the grinding head. A vertical stand (“leg”) is attached to the front edge of the rods to make it possible to fix the bracket. The bracket is attached to a hinge, which makes it possible to rotate the unit at any angle relative to the working plane.
From a bicycle
From a piece of a bicycle frame and turbine craftsmen Often they make a cutting machine. Old Soviet-made bicycles are ideal for these purposes. But more modern ones are also suitable, the frames of which are made of strong metal with a wall thickness of 3.0-3.5 mm, which allows them to withstand heavy loads.
You can look at execution drawings on the Internet or specialized literature. vertical fastenings, and pedals can be used as a turning mechanism. Taking the sample you like as a basis, you can independently bring to mind a new drawing.
A protective screen is easy to create from plywood or plexiglass. In addition to the bicycle frame, you will also need an assembly table, and brackets from reinforcement can be welded as clamps.
It is optimal to use 12 mm reinforcement for these purposes.
The frame is freed from the steering wheel (you can cut a fragment from it and use it as a handle). An element 12 centimeters long is cut off from the fork side. The fork is shortened in accordance with the turbine parameters. Then you can begin to install it using metal base(piece of metal thickness 5-6 mm).
