Making wood cutters with your own hands. How to make a wood milling machine with your own hands. DIY table manufacturing technology for a router with drawings

Before making a router with your own hands, it is recommended to prepare a drawing. The diagram shows the main elements of the tool.

A milling cutter from a drill can be made quickly, but is used to a limited extent.

Design features

A homemade wood router is used for chamfering, shaping edges, and creating decorative carvings. A similar device for metal is equipped with special cutters and is designed to work with soft metal. If necessary, you can make a router for working with plastic, plexiglass and other materials.

The main elements of the tool are the spindle, motor and cutter. Rotation from the motor is transmitted to the spindle with the working cutter. Some metal and wood routers operate on single-phase AC power. You can make handheld routers with your own hands using a small DC motor.

For this, various cutters are used. The choice of element depends on the purpose of the future tool and the material being processed. Simple models are designed for wood processing. Such units are characterized by low speed. It is more difficult to make a metal milling cutter with your own hands, since this material has a high degree of rigidity and strength.

Operating principle and classification

To manufacture the spindle, hard metal is used, which must meet certain requirements for rigidity and hardness. The operating principle of any milling cutter is as follows: the rotor is connected to a spindle onto which the cutter is fixed. When the tool is plugged in, the spindle begins to rotate. The material is cut with sharp knives.

The accuracy of the work performed depends on the rotation speed.

The stand for the router is also cut out from a piece of chipboard.

Since the number of revolutions depends on the density of the raw material, it is recommended to equip a homemade tool with a regulator.

lamellar - makes grooves;
upper - used to perform any woodwork;
edging - makes edges and chamfers.

The top router is classified into the following types:

fixed – rigid motor mount;
submersible - the motor moves with the cutter.

Narrow-profile tools are subdivided taking into account the material and parts to which it is applied:

tenon cutting machine;
for drywall;
to obtain a groove, etc.

Self-production

A hand tool, represented by a motor that rotates a cutter, can be made with your own hands. To do this you will need a cutter, an electric motor and a chuck. The motor can be taken from any working electrical appliance. The cartridge can be taken from a hammer drill, since this part can withstand greater power.

The base for the motor is PVC or standard chipboard sheets. The base is cut out and fixed to the motor. The cartridge is connected to the engine using a special adapter. This will require the help of a specialist. Appropriate milling cutters are selected for the resulting material. The tool is ready for use.

The resulting hand-held device can be turned into a machine. To do this, you will need to equip a frame of suitable dimensions and make holes in the appropriate places. Such a universal machine made at home will not be able to provide sufficient speed to carry out high-quality work. It can be used for "rough" woodworking.

You can make a CNC machine at home. It is intended for the production of a product designed on a computer. The device with numerical control allows you to perform the following work:

Milling.
Laser cutting.
Engraving.
Drilling.

A homemade machine must be multifunctional. To make it you will need an MDF board measuring 1.5 x 1.5 m and fittings. The parts are cut out with a jigsaw and drill. To prevent chips from scattering during operation, a dust extractor is installed. The resulting tool is not used for metal processing. It can be used on aluminum, bronze, foam and plastic.

A CNC machine is made by hand using an aluminum profile with a cross-section of 80x40x4 mm. Beams are cut from it:

2 pcs. 1300 mm each;
4 things. 460 mm each.

Guides are inserted into 2 channels with a cross section of 50x30x4 mm. The legs of the machine are made from similar elements of the sofa. The base frame is ready. This multifunctional tool is based on stepper motors.

The main elements of a hand router are the motor and the cutter. The remaining parts of the device act as an intermediary, ensuring uninterrupted operation of the device. Therefore, when making a hand router, it is recommended to take into account the parameters of the motor and the cutter.

A homemade hand tool has the following advantages:

low price;
processing of various surfaces;
simple structure assembly and maintenance;
easy operation.

Experts attribute the low speed of material processing to the disadvantages of homemade devices. If the device is equipped with a standard motor, which is equipped with modern household appliances, then there will not be enough revolutions to process complex elements and surfaces. To eliminate this disadvantage, high-speed motors are used. They can be removed from a modern hammer drill. The powerful unit will allow you to adjust the speed to perform carpentry work of any complexity.

Homemade milling tools have low rigidity and strength, as they are made from scrap materials. The above advantages and disadvantages should be taken into account when manufacturing and working with a hand-held homemade device.

Working with various materials requires the use of high-quality cutting tools. Most of the required types have standard parameters and are freely sold in stores, but some samples have specific sizes or shapes. They are not produced or are extremely rare. To a greater extent, the question concerns cutters that have many profile options, varieties or types of design.

Finding the right type can take too much time, so sometimes there are no other options other than making a cutter at home.

How to make a cutter

Milling cutter is a general name for a wide group of cutting tools. There are two main types:

on wood;
on metal.

There are many types of cutter designs used to perform different technological operations:

Whole.
Composite (prefabricated).
End.
End
Shaped.
With replaceable plates and others.

The production of cutting tools is a high-tech process that is demanding on the quality of the material. For example, the production of end mills consists of several stages:

Turning of a workpiece (shaping).
Milling teeth.
Processing of cutting edges (sharpening and backfilling).
Heat treatment of the material (hardening, tempering, other operations resulting in a high-quality metal structure).

To manufacture other varieties, similar or other operations are performed, determined by the type and design of the tool. Homemade cutters are only modifications of ready-made samples.

Attention! The manufacturing technology of cutting tools is complex and requires the use of precise equipment. At home, production “from scratch” is impossible; only processing of the finished tool, changing its shape or size is available.

The need to use one type or another, to obtain a certain profile or size of the cutting organ, forces you to decide the issue yourself. Let's look at how to make a cutter with your own hands at home.

Homemade wood cutters

Making a wood cutter with your own hands is possible if you have the appropriate workpiece and a machine where it will be installed. At home, an electric drill or a hand-held milling machine is usually used. The most affordable option is to change the shape of a regular metal drill, but other methods can also be used.

Let's look at how to make a wood cutter from a drill. Depending on the purpose of the tool, you will need a workpiece (metal drill) of a certain size. If you plan to manufacture a shaped cutter, then the diameter of the workpiece must be equal to the maximum diameter of the final product. Manufacturing consists of two stages:

Giving a profile.
Creating a shank.

Both operations require the use of industrial equipment. In any case, a lathe will be required to make the shank. The hand router collet is designed for a diameter of 8 mm (there are options for 6 and 7 mm). Therefore, for large drill diameters, the shank should be prepared before creating the profile. This will eliminate beating, which is dangerous when processing wood. The easiest way to create a profile is by grinding. First you need to make a template, according to which you need to constantly check the status of the profile. To work, you will need a grinding machine (emery), a grinder or a cutting wheel mounted in the chuck of an electric drill.

To create replacement plates for the milling head, either ready-made samples are used, which are given the desired shape, or blanks made of high-quality metal. The profile is created by grinding on a machine at hand.

The final operation is backing. This is the process of setting a specific cutting edge angle to ensure that the back of the edge does not contact the workpiece.

Important! Backing is a rather labor-intensive process, but necessary; it is the only thing that gives the cutter the ability to work normally.

DIY metal cutter

Making cutters for metal at home is limited to regrinding existing tools, changing the profile or diameter of the cutting part. More active intervention will require the use of industrial equipment, as it will be necessary to perform complex procedures:

Tempering of metal (a procedure reverse to hardening).
Machining, including shaping, sharpening, backing).
Hardening the cutter.

It is almost impossible to carry out these actions efficiently at home. In addition, work of this kind requires considerable professional training and experience, which not everyone has. Therefore, they are limited to only available procedures that involve minor intervention in the original state of the workpiece.

Making cutting tools at home requires the necessary equipment and suitable workpieces. In addition, you must have skills and experience, otherwise you can end up with a very dangerous product that can ruin the surface being processed and harm the craftsman himself. It is not recommended for an untrained person to carry out such work; it is better to seek help from a specialist.

Wood is the most ancient material in terms of its processing and introduction into human life. It was from wood that people assembled their first homes, tools, etc.

Such attention to wood from ancient times is completely justified, because it combines excellent strength qualities, as well as good durability and the ability to be processed without the presence of powerful tools.

However, now woodworking is still carried out using specialized equipment, since it can significantly reduce the time of work processes. We will now look at perhaps the most popular unit that performs woodworking functions - a milling machine.

1 General information

Woodworking machines do not necessarily have to be milling machines. These can also be mini-machines, vertical drilling machines, etc.

1.1 CNC milling machines
Separately, we note CNC milling machines for wood. CNC is a numerical control module.
It was specially conceived for installation on machine tools. Moreover, first of all, it is installed not on woodworking machines, but on machines for working with metal.
A CNC is a small mini-unit in which a simple reading processor or computer is installed.
When working with a CNC machine, a person simply needs to enter the required coordinates into the device. This can be done by measuring the table and mounting the element being processed is in the correct position. Coordinates can be entered sequentially.
Of course, it is possible to install and configure a CNC, and a person is quite capable of handling this task with his own hands. It’s just that the work will take a lot more time, effort, money, and you will also need experience in interacting with machine computing mechanisms.
2 Self-assembly of a milling machine
As we noted above, you can make a mini wood milling machine with your own hands. Moreover, the process is very entertaining, interesting and can give you a lot of pleasure.
In addition, creating a homemade wood milling machine does not take much time and effort. Although it all depends on specific decisions.
As a rule, two schemes for creating machine tools are used in work:
diagram using a ready-made manual router;
diagram showing the assembly of a milling unit from individual elements.

Both schemes involves using a table as the basis for a milling machine. It is mounted, connected and stabilized on the table. This allows you to use fairly cheap hand cutters.
Note that the first type of assembling a homemade unit is more preferable for beginners. After all, in essence, you only need to assemble a special table-stand for the mechanism, as well as equip it with several additional elements.
Assembling a milling unit from improvised means is a much more complex process. Here you will need to separately obtain a powerful asynchronous motor, combine its shaft with adapters and create something like a homemade spindle.
The engine itself will need to be assembled in a separate structure, connected to a power supply, stabilizers, etc. Moreover, most of these parts will still have to be purchased, although their cost in any case will be lower than the cost of the finished cutter.
But it's up to you to decide. Let us only note that the complete assembly of a milling unit from improvised means requires not only basic carpentry skills (which will completely satisfy you in the first case), but also an understanding of electrical engineering and the ability to work with mechanisms and equipment.
2.1 General principles of homemade machine design
Describing the general design of a homemade milling unit is actually very easy.
It consists of several simple elements:
table;
stands;
fastenings;
working mechanism (in our case, a manual vertical cheap mini milling machine);
strips for regulating working movement;
element for manipulating the cutter;
additional parts, consumables, etc.

The table is made of wood. You can use ready-made solutions, just adapt them to the job, or you can assemble them yourself from plywood, fiberboard and boards. Stands, mounts, etc. are assembled in the same way.

Unlike essential tools, a router is not one. You can do just fine without it. Wood and metal carvings are still performed using chisels, chisels and other simpler tools. Routers are used when woodworking becomes a real business, or when you need long-term repairs. For this you need not only a router, but also saws, grinding tools with attachments, planes and other tools. The milling cutters themselves appeared on our market relatively recently, but are already extremely popular among builders, carpenters and furniture makers.

Hand router

The router allows you to chamfer, shape edges, create decorative carvings and work with workpieces before starting more detailed work. However, milling cutters work not only with materials such as wood. A manual metal milling machine differs only in the presence of appropriate cutters, however, even in this case, it can only be used to work with soft metals. It is also possible to work on plexiglass, plastic and other similar materials. It all depends only on the type of cutters chosen.

Manual router (video)

The tool is designed as follows: the spindle is connected to the rotor, and the corresponding cutter is already attached to the spindle itself. When turned on, the spindle begins to rotate, and in the rotation state it is capable of cutting material due to sharp knives. According to all the laws of physics, the rotation speed determines the accuracy of the work. In other words, the more powerful the router, the more accurate the work it performs. However, it is worth considering the material you intend to work with: the required number of revolutions will directly depend on the density of the material. By the way, it is for this purpose that almost every router is equipped with a regulator.

According to the structure described above, a manual router has 2 main elements: a cutter and a motor. All other parts are only “intermediaries” that ensure the operation of these elements. Based on this, the parameters of cutters and motor always come first when choosing the necessary tool.

Types of hand routers

To describe all instruments of this type, it is necessary to reduce them to a standard classification.

1. By method of application:

Lamellar - a tool that is better than others suitable for making grooves connecting parts;

Edge banding (or edge) - a milling cutter designed for making edges and chamfering;

The top one is a universal hand router, as it can be used for any woodworking.

2. The universal router (upper) is divided into:

Fixed - the motor is rigidly fixed, and the milling depth itself depends on the up/down movement;

Submersible - the motor moves along with the cutter (such a tool will be much easier for beginners).

3. Narrow profiles are divided according to the materials and parts to which they must be applied:

Tenoning machines;

For working on drywall;

Grooving cutters;

Thus, the choice of tool directly depends on the scope of application. But if a router is just a motor capable of rotating a cutter, is it possible to make something similar yourself?

DIY hand router

There can be many reasons to assemble a homemade hand router, ranging from high prices to the desire to make a universal tool capable of performing a number of assigned tasks, or a router that would fully meet the carpenter’s expectations.

We will need: an electric motor, a cutter and a chuck. By the way, the motor can be from almost any electrical device. The only condition is that it must be in working order. As for the cartridge, you simply cannot find a better part than a hammer drill chuck: the principle of operation is no different, and the part is designed to operate at high power. You can use durable plastic (PVC) as a base for the engine, or you can save money and use standard chipboard sheets. Cut it out and attach it to the engine. Next, a logical question arises: how to connect the cartridge and the engine? Despite the fact that we make the router ourselves, we will have to turn to professionals for help. We will need a special adapter, which can be ordered from any knowledgeable specialist. This will take some time.

In principle, our router is ready. This router is manual. The price of such a tool fluctuates around two to three thousand rubles, taking into account all materials. If you compare with similar routers that are offered to us by online stores, you will notice a significant difference in price. All that remains is to select the necessary cutters, and you can start working. If you want to make a machine out of a hand tool, you just need to cut out the frame to the appropriate dimensions and make holes in the right places. Thus, we have made not just a manual router, but also a truly universal tool.

But there are a couple of caveats about the disadvantages of our invention. Most likely, such a router will not provide sufficient speeds for high-quality work, like a purchased one, but it will be perfect for “rough” woodwork.

Every craftsman at least once in his life had to work with wood, and in the process of this work it was impossible not to use such a mechanism as cutters. And even more so, with repeated use, their ineffectiveness during long-term use immediately catches the eye.

Constant sharpening and maintenance of the cut takes a lot of time, and in the end, production materials do not last very long, but they cost a decent amount.

In order to always be able to work with wood, it is useful to have the skill to make cutters and materials accompanying these parts, such as knives, for example.

This article will tell you exactly how to make woodworking cutters with your own hands.

Preparing the template

Stage 1. Sketching.

The materials that may be needed at this stage look like this. Using a ruler and pencil, it is worth sketching the knives, since they are a direct reflection of the future cutter. If they are not available, it is not a problem to find an example on the Internet, and then redraw its profile and follow further instructions.

Stage 2. Cut out the shape.

Depending on how many knives we ultimately need, we count out the required number with a leaf and, grabbing them, carefully cut out the shape of the future product, without catching either the “edge” or the two load-bearing sides of the knife.

Stage 3. Making the mold.

Using glue, glue the template to the workpiece and carefully saw off the excess length with a grinder. Remember: it is important to preserve not only the edge, but also the sides! So, when working with an angle grinder, you should be somewhat careful and take into account the dimensions of the product.

Manufacturing of the product

Stage 1. Preparation for sharpening.

For this process we need a stone disk like the one in the photo. Who would be sorry to use new ones for this task - you can get them already, so to speak, used ones. After all, in the process you will have to slightly change the radius of the wheel so that when working on a stand, the product will end up with the desired shape. To do this, you should use “balls”, which will help you quickly bring the stone wheel into the desired shape.

Stage 2. Making knives.

Using the same stand, we cut out the shape we need according to the template. After the wheel became the desired shape (previous stage), this became much easier to do. Total: the product has become the shape we need. What's next? Next, we sharpen it to such an extent that the metal begins to bend slightly inward - this is what should serve as a signal that it is necessary to stop the process.

Stage 3. Formation of the finished product.

So, the final stage is formation. The knives that we obtained in the previous stages need to be inserted into the empty recesses on the cutter. At this stage, it becomes clear why it was necessary to observe the proportions of the sides at the previous stages. Carefully insert the knives all the way into the cutter and voila! – the product is completely ready for use, and the funds spent are minimal.

If you strictly follow the instructions, the process of making cutter knives will take the master no more than 15 minutes. In addition, given the minimal costs, you no longer have to worry about “dulling” or the fact that the knives included with the cutter may not suit the product and serve shorter than expected.

The period of operation of these homemade knives may vary, but according to statistics, it significantly exceeds the accessory knives included with the product, which require constant sharpening and attention during operation.

Observe the boundaries of the product according to the template, strictly follow the above instructions, and lo and behold - in no more than half an hour you will have at your disposal a high-quality product for a minimal amount.
