Homemade milling machine from a grinder. Options for making a router from a grinder with your own hands How to make a wood router from a grinder

Devices for Bulgarians– you can buy it, but it’s better to make it yourself

Corner grinding machine, simply - “grinder”, has three main areas of use.

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

The development involves holding the angle grinder with your hands while work time.

However, for convenience and expanding the capabilities of the tool, many devices have been invented. Let's take a brief overview:

Tripod for angle grinder

This mini machine allows you to solve main problem when working with a grinder: if you hold the tool with both hands, who will 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 set the correct cutting angle, 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.

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. Main reason injuries - an uncontrollable grinder that escapes from your hands when the disc gets jammed in a tree has been eliminated. But the disc itself can still cause injury.

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 simpler options.

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

By installing the appropriate disk, you can get an excellent sharpening machine, or just sandpaper. The Bulgarian herself never ceases to be such. At any time, unscrew the mount and begin manual work.

If you attach a strong stop with a slot across the disk, you can process parts with high precision while holding the workpiece in your hands.

The most popular is the circular sawmill made from a grinder. Having made a strong frame and securely fastened the angle grinder under it, you get a seasonal sawing machine, which can be easily disassembled if necessary.

At the same time, you still have a grinder and a great workbench (albeit with a slot in the middle of the tabletop).

Miter box from a grinder

If you turn the tabletop under an angle grinder, you will get an excellent miter box. Using such a device, you can quickly cut a plinth, baguette, or profile from any material at a fixed angle.

You just need to install the appropriate disk, fix the tabletop at an angle of 45 degrees - and cut the platbands for windows wooden house turns into pleasure.

This machine can easily cut paving slabs diagonally, diversifying the ways of its installation.

Something similar is being released in industrial version, but the cost of such devices will scare off not only home handyman- but also a small team of mechanics.

Wall chaser

Often when laying electrical wiring or cutting passages in the wall, the grinder is used as a wall chaser. At the same time, comfort and safety during work leaves much to be desired. If you make an attachment for an angle grinder with a solid base, you can make cuts in the walls as far as the diameter of the disk is sufficient.

In essence, it is a support sole that allows you to smoothly move the angle grinder along the wall, with uniform force. When you make this device for an angle grinder yourself, take the time and install a closed case with a pipe for connecting a vacuum cleaner.

Fraser

Since any angle grinder is equipped with a powerful motor with a gearbox, it can be used to make a stationary milling cutter. Again, provided that at any time the tool is removed from homemade device, for intended use. 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.

In addition, the cutting angle can be fixedly changed, expanding the processing capabilities. It is difficult to make such devices with your own hands, but if you develop sensible drawings using computer modeling, you can design a machine no worse than a factory one.

Cooking

It would seem, where is the grinder, and where is the kitchen? Unless during repairs you can see this tool there. However, in in capable hands Nothing is impossible for an angle grinder.

Using a two-liter tin of tomato paste and a piece of galvanized steel, you can make a mill from an angle grinder in half an hour.

In the bottom of the jar we make a hole in diameter protective casing, instead of which she dresses. We put a galvanized strip on the shaft and fasten the nut for the metal disc.

We fill in half a can of grain - and after a few minutes we get coarse flour. After sifting, we get quality no worse than store-bought.

This is a rather non-standard use of the tool, but a grain crusher for poultry– time-tested technology.

Since the volumes are almost industrial, production should be approached responsibly. The materials used are shown in the illustration.

Angle grinder – indispensable tool for carrying out construction work with various materials. It is also good because additional devices (attachments, disks) can be attached to it and/or converted with little effort into another highly specialized tool - for example, into a milling cutter. Of course, an original industrially manufactured tool will in many ways be superior to such a homemade one, but for household needs it will be quite enough.

Materials and tools

In order to make a milling cutter based on an angle grinder, you will need the following tools and materials:

• The angle grinder is in working condition, the absence of any defects or malfunctions is mandatory;
• welding machine (if you are going to use metal);
• fasteners;
• screwdriver/screwdriver;
• electric drill;
• building level;
• ruler (tape measure) and pencil;
• square;
• a sheet of plywood or chipboard 1 cm thick or a sheet of metal approximately 3 mm thick;
• wrenches;
• jigsaw or saws for working with wood/metal;
• metal corners or blocks of dense wood (5x5cm);
• punch;
• set of hex keys;
• file, coarse and fine-grained sandpaper.

Procedure

To begin, decide which milling tool Do you need a stationary or manual one? Both options have their own characteristics during assembly and operation.

Stationary

If you need a still milling machine, keep in mind when designing it that its capabilities will depend on the power and rotation speed (number of revolutions) of the grinder motor, as well as the area of ​​the table for work (workbench). For processing parts made of weak wood small size A small grinder with a motor power of 500 W is enough. If the milling cutter has to work with metal workpieces, the power of the angle grinder motor must be at least 1100 W.

The design of the milling cutter consists of the following elements:

• stable base;
• movable/fixed tabletop with lined strip;
• drive.

Lamella milling machines are distinguished not by vertical, but horizontal arrangement working cutter. There are 2 options for designing a homemade milling machine:

• fixed table – movable tool;
• movable worktop - stationary tool.

In the first case, for horizontal processing of a part, the procedure is as follows:

• fix the angle grinder to the plate vertically (the cutter attachment is positioned horizontally);
• guides are installed around the table for moving the plate with the tool;
• the workpiece is fixed to work surface.

Thus, processing of the fixed part is carried out with a movable tool. In the second case, you need to ensure the immobility of the grinder and the mobility of the working surface. To move the tabletop, a structure of guides is constructed underneath it with the ability to fix the position of the working surface. The angle grinder, in turn, is mounted on a vertical frame on the side of the workbench. When a machine with a vertically positioned working attachment is required, the procedure is as follows:

• assemble a frame from pieces of wood or corners, ensuring they are rigidly fastened to each other (using welding or fasteners);
• attach to the frame chipboard sheet or plywood;
• make a hole for the angle grinder shaft - the diameter of the recess must exceed the corresponding indicator cross section shaft;
• secure the tool inside the frame using clamps or punched tape on the bolts;
• on the working surface of the table, build guides (from slats, slats, etc.) to move the part;
• sand and paint all surfaces;
• The toggle switch for turning on the tool can be fixed for comfortable use.

All heads of self-tapping screws (bolts, screws) must be recessed and not protrude above the surface of the work area. Keep in mind that the guide rails must be removable; different workpieces require different locations. It is most convenient to fix them using self-tapping screws. The tool should be located conveniently and accessible for quick replacement working attachment(cutters, discs, etc.).

To fully use any homemade milling machine, you need to purchase cutters - additional attachments for the grinder in the form cutting discs or key bits. If the first ones are replaced without problems grinding disc grinders and are easily secured to the shaft with a clamping nut, then for the second type of attachment you will need an adapter.

Manual

Most easy option– convert the grinder into a manual milling machine. Please note that in this case it is necessary to securely secure the workpiece - using a vice or clamps - in order to eliminate the possibility of vibration or shifting of the workpiece. There are several ways to convert an angle grinder into a manual router. Here is one of them.

First, make the basic base of the tool according to the drawings. Ideal option there will be a base made of a metal sheet of sufficient thickness and weight, because the mass of the base directly affects the stability of the device. Then make a fixing plate - a bracket to hold the angle grinder. The material is the same as at the base. You need to make a hole for the back of the tool, the one where the handle is located. Cut out the blanks into the shape you want.

Weld pipe sections to the ends of the product square section– for moving along vertically located guides. The guides will be longer sections of square pipes, but with a smaller diameter. They need to be welded to the base. To increase the reliability of fixing the tool, you can make and weld unique “ears” from a metal sheet. To fix the tool at the desired height, it is necessary to make a mount. You can weld 2 nuts, screw threaded rods into them, onto which wing nuts are attached by welding. With this device you can easily and quickly change and secure the required position of the tool.

Now you need to install the drill chuck as an adapter for the working cutter attachment. Pre-cut a thread inside it that matches the angle grinder shaft. Then screw it onto the shaft and fix the necessary cutter in it. Assemble the machine. Fix it in the bracket.

Test its operation. If there is no excess vibration or uncontrolled shifts during operation, everything is in order. Otherwise, you need to check where the inaccuracy came from and correct it.

Operating rules

When performing milling work on wood Don't forget to follow these simple rules:

• compliance of the nozzle on the angle grinder with the material being processed;
• Removal of the protective casing is not allowed;
• set the angular speed grinder to a minimum;
• really assess your strength - a large grinder can easily be snatched from your hands;
• work with protective gloves or firmly secure the tool;
• first check the homogeneity of the workpiece - whether there are any foreign metal parts;
• work must be carried out in one plane, distortions are unacceptable;
• do not block the button in operating mode;
• Before replacing the accessory/blade, be sure to turn off the power to the power tool.

To learn how to make a router from a grinder, see below.

If it is necessary to perform milling work and there is no money to purchase a factory tool, it is possible to make a milling cutter from an angle grinder at home. Although it will be inferior to industrial analogues, it can be used to make grooves and tenons in wood blanks, drill holes, process edges, and cut out places for installing door locks and hinges. Milling can also be performed with some other materials, the list of which is determined power of an angle grinder, taken as a basis. For home workshop homemade instrument is good option, requiring minimal financial costs.

Stationary frame-table for attaching an angle grinder

A milling machine is a device designed to process various materials(wood, metal, plastic, textolite and others): drilling, creating grooves, cutting edges and carrying out other technological operations. It can be made in the form hand power tools or a stationary machine. For use at home, you can make a router from a grinder. At the same time, it is possible to implement both stationary and manual option execution.

To make a router, in general case will be needed following materials and tools:

• a working angle grinder that will serve as a drive mechanism;
• welding machine(needed when using metal);
• fasteners - punched paper tape, bolts and nuts, self-tapping screws or self-tapping screws;
• a screwdriver equipped with different bits;
• drill with a set of drills;
• tape measure and marker (or pencil);
• level;
• square;
• plywood (chipboard) or metal sheet(about 3 mm thick);
• set of wrenches;
• screwdrivers;
• jigsaw or saws for wood and metal;
• iron corners or wooden blocks(5 by 5 cm);
• core;
• hex keys;
• sandpaper, files.

Sheets of plywood or chipboard with a thickness of 10 mm are suitable for the work.

The possibilities of a permanent installation will be determined by the following parameters:

• angle grinder electric motor power;
• number of revolutions (rotation speed) of the motor;
• the dimensions of the work table, which determine the dimensions of the workpieces being processed.

For working with small wooden parts made from fragile wood, a grinder with a 0.5 kW electric motor will suffice. If you have to process metal workpieces, you will need a device with a motor of 1.1 kW.

Algorithm for making a milling cutter from an angle grinder

The manufacturing algorithms for a stationary milling installation and its manual counterpart are different. The latter option is easier to implement: less labor and materials are required.

Stationary machines

The milling machine consists of the following structural elements:

• strong, stable frame;
• drive;
• table for performing work with a ruler (slat).

Accordingly, when creating working model installation, you will need to make these parts, and then connect them together. An angle grinder will be used as an electric drive. It will need to be securely fastened to the table top.

The stationary machine can be made in two versions: with an angle grinder fixed on the table or with a movable installation of an angle grinder. The first one is quite easy to implement practically with your own hands. It should be taken into account that the working tool can be secured so as to perform processing in horizontal or vertical planes. The order in which the installation is assembled depends on this.

Machine with workpiece processing in horizontal plane (with a vertical cutter position) are assembled in the following sequence:

• make a frame from metal corners(they are connected by welding) or wooden blocks (fastened with self-tapping screws);
• sheathe the frame with chipboard or plywood, securing the sheets with bolts;
• a hole is cut out in the countertop for the grinder shaft (larger in diameter than its cross-section);
• using punched tape or clamps, attach the grinder to the table top with bolts from below, approximately as shown in the photo below;

• on the surface of the table top wooden slats(pieces of chipboard or plywood) install strips that act as guides along which the workpiece will move;
• wooden and metal parts of the structure are painted (after having been cleaned with sandpaper);
• For ease of operation, attach the toggle switch for turning on the grinder.

The bolt heads located on top of the tabletop must be flush with its surface. Therefore, you will need to drill holes of the appropriate size for them. The guides are removable structural elements. They need to be rearranged for each workpiece. They are often fixed using self-tapping screws.

It is necessary to provide such access to the grinder so that it is convenient to change attachments.

Using a toggle switch, you can supply power to the power tool by simply locking its button in the on position. More difficult option there will be a redo electrical diagram Angle grinder.

Option with horizontal cutter arrangement is implemented in a similar way, only the angle grinder is fixed to the side of the structure, resulting in something similar circular saw. Appearance The created machine is demonstrated in the photographs below.

To use the machine you need install cutters. There are varieties of them on sale that resemble regular cutting discs, which are fixed to the shaft using a clamping nut. An adapter is required to use key bits. Moreover, on one side it has a threaded seat (for screwing the grinder onto the shaft instead of a nut), and on the other, for fixing the cutter.

At mobile version fixing the angle grinder, it is easier to remove it if necessary in order to use it for its intended purpose. It is much easier to make a manual router than to create a mechanism that allows it to move back and forth, as well as left and right. Working with such a tool will require securely fastening the workpiece so that it does not vibrate or move, for example, in a vice or using clamps. This will largely determine the quality of the work performed, as well as the convenience (speed) of its implementation.

There are many options for making hand-held tools from angle grinders for milling. In this case, they use different materials. Creation method hand router on wood from an angle grinder is demonstrated in the video below.

Hand tools They are more reminiscent of attachments for an angle grinder, allowing you to use it like a router. The most simple models do not provide for vertical movement of the cutting attachment. They are designed to perform simple operations.

If we compare manual and stationary options homemade milling cutters, then it should be noted that the quality of processing of the latter is higher. But the first ones are easier to make, and the grinder can be easily removed if necessary. The tool must be handled carefully, following safety precautions. It's great when an angle grinder has speed controller. This allows you to set the desired rotation speed of the cutter while working with different materials.

For various works In a home workshop, it is not always advisable to purchase specialized power tools, which, as a rule, are quite expensive. Do-it-yourself devices, which include a milling cutter made from an angle grinder, are more relevant in such situations. Using such a device, the basis of which can be a household electric drill, you can perform various technological operations - milling, edge processing, forming tenons and grooves on the surface wooden blanks, preparation seats For door hinges and castles, etc.

Materials used

Making your own milling cutter from an angle grinder to equip a home workshop requires fulfilling certain conditions, the main of which are ensuring reliable fixation of the power tool in vertical plane and its movement relative to the surface of the workpiece.

In order to make your own milling machine from a grinder that satisfies the above conditions, you will need the following components and consumables:

• grinder or electric drill, the drive motor of which must be in working order (in addition, structural elements, with the help of which these devices will be fixed to load-bearing structure, must be sufficiently strong and reliable);
• the base on which the future router will be fixed (the surface of a desktop or workbench can be used as such a base, which should be highly reliable and stable, and also ensure ease of working with);
• thick plywood or thin sheet metal(from these you will make with your own hands the part of the router structure on which the grinder or electric drill will be fixed);
• welding machine (if sheet metal will be used in the design of your router);
• fasteners (clamps, screws, bolts and nuts);
• standard set of locksmith tools.

Thus, to make a milling cutter from an angle grinder with your own hands, you will need materials that are available in almost every home workshop or in any garage. Accordingly, in order to make such a machine and start using it, significant financial investments will not be required, which cannot be said about the situation when purchasing production model such a device.

Manufacturing algorithm

Making your own milling cutter based on a grinder or drill is carried out in the following sequence:

1. The base of the milling machine is made from thick plywood, chipboard or thin sheet metal, which consists of two walls located opposite each other. One of the walls of such a base, which is not used to fix the grinder or drill, can be made movable. This will allow you to change its spatial position depending on the length of the part that will be processed.
2. A metal cone is fixed on the moving part of the future milling cutter, which is used to hold the workpiece during processing.
3. The tool with which processing is performed on a home-made machine is placed on the side of the frame. You can use tools of almost any configuration and any size on such a router.

In the event that the milling machine will not be manufactured on the basis electric drill, and on the basis of an angle grinder, a special adapter will have to be included in its design, which will ensure the fixation of the sleeve used to rotate the workpiece. If the basis of a homemade router is a drill, then such a sleeve is simply fixed in the chuck of the power tool.

Thus, making a router from a grinder or an electric drill with your own hands is simple. To do this, you don’t even need to invent your own device design - just use ready-made ideas, which have already been tested in practice by many home craftsmen.

To carry out a variety of work at home, it is not always worth spending cash for expensive instruments. In such conditions, it is more optimal to manufacture devices from existing ones. Such mechanisms include a milling cutter made from an angle grinder, which allows for milling, the formation of various grooves and tenons, and the processing of edge surfaces.

What you need to prepare for making a router

Making a milling cutter from a grinder for home use requires the provision of certain conditions, in particular, reliable fixation of the tool on flat surface in a vertical position. To make your own milling machine from a grinder saw, you will need the following materials:

• electric drill or grinder;
• sustainable and reliable design, serving as the basis;
• plywood on which the device will be fixed;
• welding machine, if there is a metal base;
• clamps, bolts, nuts and other fixing parts;
• locksmith tools, as well as hex keys.

To assemble a router at home, you need materials and parts available in every garage or workshop. And from this it follows that the manufacture of such a machine will not require serious cash injections, which cannot be said about the purchase of special equipment.

Machine manufacturing process

The process of assembling a stationary and manual installation for milling is very different, since creating a manual wood router requires less material, labor and other resources.

Stationary installations

The milling machine package includes the following structural elements:

• stable bed;
• drive;
• surface for milling work, equipped with a ruler.

When creating a router from an angle grinder, it is necessary to connect all the components. In this case, the electric drive will be a power tool mounted on the table top.

Stationary installation can be performed in several options - with a fixed angle grinder or with a movable device. The first modification is quite easy to implement at home. The working device can be fixed to perform work in a horizontal or vertical direction. The order of equipment installation depends on the plane of the planned processing.

A machine operating in a horizontal plane is manufactured following the sequence of actions:

• assembling a frame from bars or metal corners;
• covering the frame with sheets of plywood;
• forming a hole in the tabletop with a diameter exceeding the grinder shaft;
• fastening to the lower surface of the instrument table cover. Fastening is carried out using self-tapping screws, screws, clamps;
• strips are formed on the surface of the tabletop, acting as guides;
• the structure is cleaned and then painted.

When assembling the machine, it is necessary to provide access to the grinder without complicating the process of changing attachments. For comfortable operation, you can attach the electrical equipment toggle switch. Pre-locking the button in the on position allows power to be supplied to the tool.

Horizontal position of the cutter

This device is manufactured similar to a vertical machine. The difference lies in the place where the grinder is attached - the power tool is fixed on the side surface of the structure and resembles a circular saw.

To use the machine, a cutter must be installed. In specialized stores there are various cutting discs - cutters, which are secured with a clamping nut. If it is necessary to use key bits, an adapter is required, equipped with threads for attaching the mechanism and a place for fixing the cutter.

Hand milling tool

This milling cutter is significantly easier to manufacture compared to stationary devices. To perform work using this tool, reliable fixation of the workpiece is required, eliminating vibration and all kinds of displacement. As a rule, such fastening is a vice or clamps. The speed and quality of work depends on the quality of fixation.

Scheme for attaching an angle grinder to a milling machine

There are quite a lot of options for making manual milling devices from an angle grinder, as well as the materials available for use. In most cases, hand-held devices are attachments that allow them to be used for milling operations. Elementary models do not allow moving cutting attachment in the vertical direction, since they are designed to carry out simple operations.

In case of comparison of homemade milling cutters made manually or in the form of a stationary installation, stationary cutters significantly outperform in terms of processing quality. And if we are talking about simplicity and versatility of use, then it is in the lead hand tool. Performing milling work using hand-held device or permanent installation requires strict adherence to safety rules.
