Do-it-yourself options for making a milling cutter from a grinder. Do-it-yourself wood router from a grinder Do-it-yourself manual milling cutter from a grinder drawings

A milling cutter is often used to carry out various work in the home workshop. Such a tool has become very widespread, as it allows you to get a variety of products. A fairly common question is how to make a router. This is due to the high cost of the tool. Often they make a manual milling cutter from a grinder with their own hands due to the fact that the use of a ready-made structure as a base greatly simplifies the task. Let's consider the features of the work being done in more detail.

Milling cutter design

There are just a huge number of milling cutters on sale. Among the design features, we note the following points:

1. The main movement is received by the nozzle, which is represented by a cutter of various types. It should be borne in mind that a milling cutter from a grinder is also used with special nozzles, which you cannot make with your own hands.
2. In order to make the hand milling cutter easy to use, a special limiter is created. It can be of various sizes.
3. The nozzle is driven by an electric motor. In this case, a ready-made design is immediately applied, which has an electric motor and a drive. At the same time, the tool has its own convenient controls and holders.

In general, we can say that the woodworking machine from the grinder does not differ much from the original tool used as a base. That is why many people do this kind of work themselves.

Necessary materials and tools

Before proceeding with the direct work, you should purchase the required materials and tools. Do-it-yourself milling machine from a grinder can be made if you have:

1. A suitable electric drill or grinder. When choosing, special attention is paid to the power of the installed electric motor. The structural element of the device, which is responsible for fixing the nozzle, must be durable and provide reliable fastening at the time of operation.
2. Level and square, which are required to improve the accuracy of the product.
3. Set of wrenches.
4. Drill with a large set of different drills. To fix the main elements, you will have to create special holes, for which a drill is suitable.
5. Screwdrivers. To work with various fasteners, a set of screwdrivers is required.
6. Electric jigsaw, as well as special saws for wood. They are used to work with plywood and other wood, allow you to achieve higher quality when cutting.
7. Thick plywood or sheet metal is required in order to make an angle grinder. They are used to fix the main element at the time of its application.
8. A welding machine is also required when carrying out such work. An example is that you have to work with sheet metal when creating a base.
9. Fasteners are also required to build the device. The most commonly used bolts, nuts and screws, as well as clamps of various materials.
10. Sandpaper to obtain a surface of the required quality. When using plywood, it has to be modified, since even minor defects can complicate the milling process.

Particular attention should be paid to the choice of grinder, which is used as a basis for creating a tool. The main requirements are:

1. The structure must be in good technical condition. Even minor defects can lead to reduced performance and functionality.
2. Too little power becomes the reason why the scope of the router is significantly reduced. Low-power versions with prolonged operation begin to warm up. When overheated, the electric motor fails.
3. For the milling cutter, versions with large dimensions are suitable. Due to this, you can conveniently fix the main elements. However, when using too heavy options, the milling process can become more complicated.

In addition, the work requires a standard set of locksmith tools. Almost everything you need can be found in every home workshop. The collet for the grinder is also made by hand from metal.

Manufacturing procedure

You can make a lamellar milling cutter from a grinder yourself, for which you just need to pay attention to the basic recommendations. They look like this:

1. From previously selected plywood or sheet metal, the foundation is being created. It is represented by two walls that are located between each other. In some cases, one of the walls is made movable, which makes it possible to adjust the base depending on the length of the workpiece. The connection of individual elements is carried out using various fasteners. Stainless steel versions are recommended as they last much longer and do not corrode.
2. A cone made of metal is fixed on the movable part. It is required to fix the workpiece at the time of processing. You can make a milling machine from a grinder using a ready-made cone, which is removed from other devices.
3. The tool used as a base is placed on the side of the case. Suitable for this tool of any size and power.

It should be borne in mind that when making a cutter from a grinder with your own hands, you have to create a special adapter for fixing the sleeve. You can also make it at home from improvised materials.

In conclusion, we note that it is suitable for use in the case of small-scale production. This is due to the fact that most cutting machine options are not designed for long-term use. In addition, even a high-quality version of the performance will be inferior in terms of functionality to purchase offers.

In the home workshop, each type of tool will, by the way, the same applies to a home-made milling cutter from a grinder.

And if that, and was told earlier, then it's time to talk about how to make a milling cutter from a grinder with your own hands.

In fact, everything is quite simple, and if there is an old unnecessary drill or grinder in the garage, then the milling machine can be made quite simply. The main parts of a milling machine from a grinder or a drill are a cutter, a rod on which it is mounted and an engine that rotates it. That's actually all, about what in order.

So, in order to make a grinder from a grinder with your own hands, you will first need to prepare:

In principle, that's all, although in the process of making a grinder from a grinder with your own hands, you may need additional bolts or self-tapping screws, but this stuff, as a rule, abounds in every garage or in the home master's hozblok.

First, the base of the router is made of thick plywood or boards. It consists of two walls located opposite each other. The distance of one wall to the other can be made fixed, or it can be made so that one of the walls, on which the drill is not fixed, moves closer or further depending on the length of the workpieces.

A metal cone is fixed on the moving part of the homemade milling cutter, which will hold the workpiece with its sharp end. On the side, right on the frame, there are milling cutters for wood. They can have a different configuration, length and width of workpiece processing.

A do-it-yourself milling cutter from a grinder is done almost exactly the same, the only difference here is in the way the sleeve is fixed for rotating the workpieces. And if in a drill it can be fixed directly into the cartridge, then when using a grinder as a milling machine, you will have to make an additional adapter.

A milling cutter from a grinder or a do-it-yourself drill can be made quite easily. There are many videos on the Internet on this topic. You can easily change and add something to the design of the milling cutter from the grinder with your own hands from yourself, the main thing is that it would be convenient to work behind a home-made machine.

Hello everyone, if you need a router, but do not want to spend money on buying it, this is not a problem, because you can do it yourself! Materials for this will require very little, as well as cash costs. Everything is assembled on the basis of a small grinder and its design does not change. That is, the homemade product is just a nozzle for the grinder, and you can put it on when you need it. In general, the use of an angle grinder as a power unit for a router is a rather interesting solution, because an angle grinder has a considerable torque and high speeds.

The whole structure is assembled from available materials, these are sheet metal, steel square pipes, bolts with nuts, and so on. The only thing you may need to buy is a drill chuck, but it is inexpensive and is sold in almost all tool supply stores. A thread is cut in the cartridge, and it is screwed directly to the shaft of the angle grinder, this is very convenient. So, let's take a closer look at how to assemble such a router!

Materials and tools used

List of materials:
- steel pipes of square section;
- Sheet steel;
- bolts and nuts;
- Bulgarian;
- drill chuck;
- dye.

List of tools:
- welding machine;
- drill;
- Bulgarian;
- drawing tools;
- a marker or a piece of chalk.

Milling process:

Step one. Making the base
First of all, we will make the base, that is, the lower part of the device. For this we will need sheet steel. It is better to choose thicker metal so that we have a good weight at the bottom, this will allow the car to stand stably. We make the necessary measurements and proceed to cutting. The author cuts everything out with a grinder, and then cuts off the excess with a grinding disc.

Step two. Making a bracket for a grinder
Next, we need to make a latch, that is, a bracket that will hold the grinder. It is also made from sheet metal. First, we drill a hole for the part of the grinder where the handle is attached. Well, then cut out the blank of the desired shape. Pieces of square pipes are welded to the ends of the product, as a result, this entire structure will “ride” on guides in the vertical direction. As guides, the author used square pipes of smaller diameter, they are welded to the base.
For additional fixation of the grinder, we make and weld "ears" from sheet metal.

Step three. Retainer
We will need to fix the drill at a certain height. To do this, the author welded two nuts and wrapped threaded rods in them, to which wing nuts were welded. Now you can easily and quickly fix the position of the angle grinder with your hands.

Step four. Installing a drill chuck
The drill chuck is screwed directly onto the shaft of the grinder. To do this, you need to cut the appropriate thread in it. You will need to choose the right tap, check it on the nut from the grinder.

Step five. We assemble and test the car
To assemble the device, we need to fix the grinder in the bracket. This is done quickly and easily. You also need to screw the cartridge from the drill and clamp the desired nozzle in it. That's all, the car is ready. We set the desired depth and get to work. The author’s machine wonderfully processes a chipboard sheet, and this material is quite strong, but at the same time fragile. The machine copes with the task without problems. You can work this way for quite a long time, because the grinder works with almost no load.

That's all, the project is over, I hope you liked it. Good luck and creative inspiration if you decide to repeat. Don't forget to share your crafts with us!

Many home craftsmen decide to assemble a milling machine with their own hands. Buying a specialized device for the manufacture of printed circuit boards or other work is quite an expensive pleasure. Having at your disposal three printers, a drill or a grinder, you will be able to make a full-fledged milling machine with your own hands. Drawings and instructions will help in achieving the goal.

It is not uncommon for a home workshop to require a milling machine. It can be assembled from a drill, printer or grinder. There are a number of other options adapted to specific drawings.

Before making a device for printed circuit boards or the production of small parts, you need to familiarize yourself with the design features of a factory desktop machine. It is not made from a drill and definitely not from a printer. But you will have to follow the general design principle when assembling the machine with your own hands.

A standard table router consists of the following elements:

• Base or bed;
• Desktop;
• Drive unit;
• Electrical engine;
• Work tool.

If the base and the desktop can be made from improvised tools, then a working slotting head, an electric motor and cutters are somewhat more difficult to obtain.

Considering the option of using a printer to make a CNC machine, it is worth noting the presence of stepper motors in their design. The drawings provide that to assemble the router, you need to disassemble not one printer, but two. This is due to the fact that three stepper motors are required. There are only two of them in one printer.

In general, making a CNC machine is recommended for those who have experience in assembling simpler structures. PCB fabrication capability, XY table and slotting head are auxiliary components of the milling machine. Do you need a slotting head or PCB device? It depends on the goals you set for yourself.

The creation of printed circuit boards or a workable slotting head are components whose functioning is directly dependent on technical specifications. These parameters directly affect what capabilities your milling machine will have. Namely, the following characteristics play a role:

• The frequency of rotation of the electric motor;
• Electric motor power;
• Desktop dimensions;
• The maximum weight of workpieces that a milling machine can process.

Assembly steps

If you decide to make a homemade milling unit, then you have to go through several main stages on the way to the coveted machine.

Whether he will be able to print circuit boards and will have a slotting head on it depends on you. However, the presented instruction does not provide for the manufacture of boards. Exactly like the slotting head is missing here.

The presented home-made machine consists of several components, the manufacture of which we will tell you separately:

• Desktop;
• Bed;
• Electric drive.

Desktop

This desktop is not the easiest to assemble. But it has a robust design, which is important for a heavily used milling machine.

To assemble the table, you will need:

• Sheet of plywood or chipboard;
• Transparent plastic No. 6;
• Wooden plank;
• aluminum plate;
• Glue;
• fasteners;
• Metal profile with a T-slot;
• Sandpaper is fine-grained;
• Electric jigsaw;
• Fraser with copier.

The lid is made first.

1. From plywood (preferably No. 19), cut a rectangle measuring 500 by 600 mm. To increase reliability, line it with plastic or textolite 2 mm thick. When cutting on each side, make an allowance of 3 cm.
2. Apply glue to the glue and plywood, and then press firmly. When the glue hardens, the excess can be cut off.
3. Cut out the plywood longitudinal and side lining. They need to be glued along the edges of the sheet. The width of the overlays is 4 mm.
4. With a disk cutter, make grooves in the edge trims. Attach the cover to the stop with the plastic part (it is the top). Grooves in the edges will be required in order to secure the T-profile.
5. Carriage. For a milling machine, the carriage plays an important role. The carriage is used to move the workpiece. Different drawings offer their own options for how the carriage may look. Determine the type of device that is best for you. If the carriage is absent, nothing bad will happen in a home workshop. But still, the carriage expands the possibilities of working on a milling machine.

Once you've assembled the cover, move on to the mounting plate.

1. Under the plate, an opening is made in the manufactured tabletop.
2. From a sheet of aluminum you need to make a plate. This is a square measuring 300 by 300 mm.
3. From the edge of the cover, indent 125 mm and draw a straight line, which should be divided into 2 parts.
4. Position the plate so that the diagonals drawn through it can intersect at the center of the straight line. Draw a contour for the plate and cutouts.
5. A cutout is made with an electric jigsaw, a plate is applied and fastened with double-sided tape.
6. Install auxiliary rails around the perimeter of the mounting plate. Set the router to 3mm. In this case, the cutter must pass along the edges of the rails. Choose a material that is 0.5 mm thicker than the thickness of the mounting plate.

bed

• To make the bed, you can use plywood number 19;
• You will need 4 ties and two supports. The dimensions of the first are 520 by 80 mm, and the supports are 520 by 290 mm. Fix with glue and screws;
• For electrical wiring, a rail measuring 51 by 42 by 19 mm is cut out and glued;
• Supports are fixed from the bottom of the cover. In the screed, make holes for the screws that will go into the cover.

Electric drive

If your homemade coordinate table is ready, the working head is waiting in the wings for the manufacture of printed circuit boards or other parts, the most important thing remains. Your homemade machine needs a drive, due to which the milling equipment will function.

Characteristics should be selected based on what parameters the head, cutters should have, and for what purposes the milling machine will be used.

1. If your task is to sample small and simple workpieces made of not the most durable materials, then a 500 W motor is enough.
2. If the machine is designed for complex work with metal products, choose a drive with a power of 1.1 kW.
3. You can make a milling machine from a grinder with your own hands, just like making a unit based on a drill. An unnecessary power tool is suitable as a drill or grinder. Make sure the drill is working properly before using it. Instead of a drill, you can use a stationary engine or borrow it from other electrical equipment.
4. The best option for an electric motor for a milling machine is an asynchronous motor powered by a three-phase network. But in the conditions of home use of a milling machine, this is far from always possible.

Last steps

The following activities can be attributed to the final assembly processes of the machine:

• Treat wooden elements with paints and varnishes to protect them;
• Fasten a couple of pieces of the metal profile to the table and stops;
• Set the toggle switch to turn the machine on and off. Don't forget the parallel stop and safety guard;
• A tube is installed on the inner surface of the stop, which will serve as a dust extractor;
• Install the mounting plate on the prepared site. Homemade cutter is ready.

From an ordinary drill, you can assemble a good home-made milling machine. Based on video instructions and drawings, your machine may have a carriage, a slotting head, and even a CNC module.

To carry out a variety of work at home, it is not always worth spending money on expensive tools. More optimal in such conditions is the manufacture of devices from existing ones. These mechanisms include a milling cutter from a grinder, which allows milling, the formation of various grooves and spikes, and the processing of edge surfaces.

What you need to prepare for the manufacture of a milling cutter

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

• electric drill or grinder;
• stable and reliable design that serves 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 the creation of a manual wood router requires less materials, labor and other resources.

Stationary installations

The following structural elements are included in the package of the milling machine:

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

When creating a milling cutter from a grinder, it is necessary to connect all the components. In this case, the electric drive will be a power tool fixed on the table cover.

Stationary installation can be performed in several versions - with a fixed grinder or with a movable device. The first modification is quite simple 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.

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

• frame assembly from bars or metal corners;
• sheathing the frame with plywood sheets;
• the formation in the countertop of a hole with a diameter exceeding the grinder shaft;
• fastening to the bottom surface of the tool table cover. Fasteners are carried out using self-tapping screws, screws, clamps;
• planks 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 nozzles. For comfortable activities, you can fix the toggle switch of electrical equipment. Pre-locking the button in the on position allows power to be supplied to the tool.

Horizontal cutter

This device is made like a vertical machine. The difference lies in the attachment point of the grinder - the power tool is fixed on the side surface of the structure and resembles a circular saw.

To use the machine, the installation of a cutter is required. In specialized stores, there are various cutting discs - milling cutters that are fastened with a clamping nut. If it is necessary to use keyed nozzles, an adapter is required, equipped with a thread for fastening the mechanism and a place for fixing the cutter.

Manual milling tool

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

The scheme of fixing the grinder for the milling machine

There are quite a few options for manufacturing manual milling devices from a grinder, as well as 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 you to move the cutting nozzle in the vertical direction, as they are designed to perform the simplest operations.

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