DIY wood milling machine: step by step instructions

Workbench

This is a dedicated workflow table. It can be equipped with various auxiliary elements. Its parameters are determined by the amount of free space in the room. The planned scope of work is also taken into account.

Today, the most common types of milling table workbenches are:

Static. This is a complete working platform.
Portable. It is a desktop version, quickly assembled and allows for milling operations.
Aggregate. It has such capabilities, due to which the sawing area is expanded.

For a household workshop, item 1 is optimal. The second type is suitable for work with small details and has limited functionality. For the third, there should be a spacious room.

Application features

Of course, just mounting a router from an electric drill is not enough - you need to properly care for it in order for it to function for a long time. The experts give several recommendations as follows.

All wood surfaces need not only to be thoroughly sanded with an emery cloth, but also to be treated with a protective coating to increase the ability to resist various adverse influences from the outside.
The control system of the device should be carefully worked out so that it is extremely comfortable.
Certain additions can be made, such as a system for cleaning the working area from chips. For example, install a small nozzle that you can attach to a hose from a simple vacuum cleaner.

Cutting disc for drill

If it is necessary to use angle grinder, but its absence, it is allowed to use a cutting wheel for a screwdriver or drill. In order to be able to use this device, it is required to purchase or manufacture a special attachment that ensures reliable fastening of the cutting disc.

The cutting disc must be fastened using a special adapter

Using a drill bit for a cut-off wheel has several advantages, including:

the ability to process metal in places where it is difficult to reach with an ordinary "grinder";
versatility, as the user only needs to change the accessory without having to change the tool.

The disadvantages of this method is the need for full compliance with safety rules when operating the cutting tool. Also, the negative aspects include:

decrease in work efficiency due to the lower number of revolutions;
limited thickness of the processed metal 5 mm.

It must be taken into account that the shaft of the power tool can rotate in both directions. When cutting, it is necessary to ensure that its rotation is carried out exclusively clockwise.

A variety of cutting blades allows you to get a versatile tool from a drill

Active use of drill attachments allows you to significantly expand the range of applications of this tool, up to use as equipment for plucking poultry or mixing a solution. Therefore, when performing construction or repair work, you need to think about the need to purchase such a device. You can learn more about the features of metal cutting attachments from the video presented.

Manufacturing technology and recommendations

A homemade cutter has limitations on the materials that can be processed with it. Manufacturing of cutters for own needs, as a rule, is associated with working with soft steel grades. That is why such a homemade tool is able to cut wood quite effectively, but when processing harder materials it quickly becomes dull.

In order to make their own milling tools, craftsmen use cuttings of steel bars or reinforcement. If reinforcement is used as a workpiece, then its ribbed surface is leveled using a lathe.

Diagram of a homemade cutter

The technology for making a homemade wood cutter from such a blank is as follows:

On that part of the cylindrical workpiece, where the cutting part of the homemade tool will be formed, half the diameter is cut off.
A smooth transition is formed between parts of the workpiece with different diameters.
Another quarter of the diameter is removed from the processed section of the workpiece; with the untreated part of the bar, such a section of the workpiece is also connected with a smooth transition.
The processed part of the workpiece is given a rectangular shape, for which its lower part is cut off. The thickness of that part of the workpiece, on which the working part of the tool for woodworking will be formed, should be 2–5 mm.

For cutting the rod, you can adapt a grinder and a drill, and the formation of the working part can be performed on a sharpening machine

In order for a do-it-yourself wood cutter to be used to perform efficient processing, the following recommendations must be followed in its manufacture.

The cutting edge must be sharpened at an angle of 7-10 °. If you make it sharper, then it will have poor sharpening and low cutting properties.
To give the cutting part of the tool the required configuration, diamond-coated needle files or angle grinders with discs specially designed for metal work are used.
If a homemade wood cutter must have a complex configuration, then it is allowed to bend or flatten it.

The cutting edge is lapped with a diamond disc, then the surface is brought up with grinding paper

With a small thickness of the cutting part, a do-it-yourself milling tool has a rather low working life. To slightly increase the service life of such a cutter for wood, the corner on the bottom of the tool, located opposite its cutting edge, can be slightly rounded.

Device add-ons

There are several devices, adding which you can make this device more convenient to use, as well as slightly expand its functionality. For example, you can add a device such as a microlift, which will move the drill in a vertical direction. If everything became clear with how to make a wood milling cutter from a drill, few know how to make a microlift, and therefore here is a short instruction:

Guides are needed. Two metal rods can be used as them.
To fix an electric drill, you must use a platform that will be made of the same plywood or chipboard.
An element such as a threaded shaft and a nut will be responsible for the movement of the electrical device in the vertical direction.
It is necessary to use suitable tools that will be able to hold the drill in the selected position.

Equipment design and operation

If you look at the drawing of a professional, you will notice that its design includes many different mechanisms and assemblies.The desktop home machine, in contrast to the serial one, has a simpler design, consisting of a limited set of required elements. Despite the simplicity of the system, a homemade milling machine is a fairly functional device and allows you to successfully solve many problems associated with the processing of metal and wood blanks.

One of the options for a homemade milling machine. The lack of an insufficiently developed drill mount, but from here you can borrow the design of the bed

The basis of any such machine is the bed, which must be rigid and reliable in order to be able to withstand the required loads. The next important element of a homemade milling machine is a drive, the rotation from which will be transmitted to the working tool. As such a drive, you can use a hand drill or a separate electric motor with a sufficiently high power.

To place and fix the workpieces that will be processed on such equipment, its design must necessarily include a working table with fastening elements for the processed parts. Processing on both professional and home milling equipment is carried out using a special tool - a cutter with a sharpened working part.

Large machine with powerful electric motor

When making a mini-machine for the home, you should not save on components. They should only be of high quality, as this directly affects the reliability and performance of your equipment.

The technical characteristics that your home desktop machine will acquire will depend on a number of parameters. These include the dimensions of the desktop, as well as the permissible weight and dimensions of the workpieces that will be placed on it. An important factor affecting the performance and power of the equipment is the power of the drive installed on it and the maximum number of revolutions that it can provide.

Another option for a homemade milling machine

Milling machines and their varieties

Different types of milling machines differ significantly from each other both in design and in purpose, some are intended only for wood processing, others for metal, there are also universal models. A number of structures have manual control, while others work in automatic mode, the simplest options can be made by hand, and there are complex factory-made structures.

Consider several types of machines below, you can also, if you wish, find drawings that relate to their self-production and design.

The vertical type of milling machine is very common. In them, the following cutters act as working tools:

cylindrical;
end;
shaped.

Drilling work can also be carried out. With this machine you can process:

grooves;
gear wheels;
corners;
vertical and horizontal metal surfaces;
frame elements.

A feature of another type of machine, horizontal, is that the spindle is located horizontally. Thanks to this type of construction, you will be able to machine small parts. The versatility of such a machine is due to the use of shaped, angle, end, end and cylindrical cutters. The standard factory equipment does not make it possible to process parts along a helical surface, in which case it is possible to use drawings to finalize the design with your own hands.

Drilling and milling machines help to process horizontal, vertical and inclined surfaces, as well as grooves of dimensional parts. They are designed for manual metal work.

The machine has a milling and drilling head that can perform tilted drilling and machining surfaces that are angled to the horizontal axis. And the working head can also work in reverse mode.

Unit classification

There are three categories of routers in total:

Professional. Workpieces of various sizes and in large quantities are processed. This involves a wide range of cutting tools.
Household. In terms of functionality, they are suitable only for home workshops.
Manual.

Each classification has its own subspecies. So professional machines have the following varieties:

Standard. They are used to implement template operations. Their equipment allows you to perform many jobs and give the workpieces the required configuration. The cutting arsenal includes: cutters, drills of different diameters, special knives.
Copiers. They perform artistic operations: applying complex images, positioning samples on different surfaces, decorating ornaments. In this work, the accuracy is guaranteed because the workpiece is fixed by the vacuum method.
For vertical machining of parts (top to bottom). Here, grooves with the desired width and depth are cut, fasteners are prepared. Parts are cut to the required length.

For horizontal work with workpieces. Here the spindle axis is horizontal in relation to the floor. There are cylindrical and end mills.
Carrying out simultaneous processing from two sides. Are versatile. Various profiles are processed here. No production of furniture components can do without these machines: stands, legs, supporting elements, etc.
Equipped with CNC devices. An electronic complex based on a special microprocessor is integrated here. It contains a program that determines the algorithm of operations. Due to this, the accuracy, quality and dynamics of work, and the labor productivity of a CNC milling machine are significantly developed.

Household models are small in size and weight. They implement basic functions (planing, drilling, grinding, sawing). Their types:

Desktop. It is characterized by ease of operation and service.
Manual. Used to work with small parts. On it, grooves of small sizes are prepared, which are required for the articulation of separate components.

Advantages and imperfections of an electric drill cutter

Cut a small panel out of the chipboard and make 4 support bars for it. The materials used must be of high quality and strong. Cut a semicircular hole on the table top with an electric chop or a jigsaw. Make slots for the thrust sheet and retainers. Attach the panel to the motor using bolts or special fasteners.

The router must be fixed to the table using bearing assemblies. In order to increase the quality of fixing the electric drill in a vertical position, you need to add a block of wood in the upper part of the rack. He will play the role of a stop for an electric drill. At the final stage of creating a router, sand all its wooden surfaces with sandpaper. The work area must be on a solid and durable foundation.

A self-made construction has obvious advantages, the key ones of which are the following:

a home-made machine will cost an order of magnitude cheaper than a factory one;
a milling cutter from an electric drill makes it possible to work with surfaces of various types;
assembling the device is quite easy to do, not counting the moment the electrical wiring is installed;
ease of use;
ease of maintenance.

There are few significant flaws in homemade equipment. The main shortcomings include the following points.

A manual router made from scrap materials is not durable.
The part speed is too slow.
The resources of an electric motor taken from an old household device are not enough to function with difficult materials and surfaces, in particular, with metal. This defect can be eliminated. For this, it is advisable to take a high-speed electric motor from a hammer drill. This will allow you to adjust the number of revolutions for different materials.

For information on how to make a milling cutter from a drill with your own hands, see the next video.

Advantages and disadvantages of a homemade tool

As the main advantage of a do-it-yourself milling cutter, there is no need to buy an expensive professional machine. Indeed, even with the help of the simplest device, it will be possible to cut grooves or process the edge of a wooden blank.

To use a drill as a router, you will have to purchase special cutters in the store. They are cylindrical, end, end, angular, disk and figured. With the help of a shank, they can be easily fixed in the chuck. It is also not difficult to change the nozzles, but the cartridge can be unscrewed from prolonged work and strong vibrations. Therefore, when working with a hand-made tool, you will have to constantly check and tighten it.

As the main disadvantage of a home-made milling cutter, one can single out the impossibility of long-term operation under heavy loads. Also, it does not differ in a large number of revolutions. The maximum number of revolutions for a drill reaches 3000, while for a router, 4000 revolutions per minute are considered the minimum. This greatly affects the purity of processing. After all, the faster the cutter spins, the more beautiful and accurate the edge of the material will turn out. Therefore, after milling with a homemade machine, the workpieces will have to be skinned.

The drill motor is also much weaker than the router motor. It is designed for short-term operation, therefore, under heavy loads, it begins to heat up. Each time you have to wait for it to cool completely.

It is possible to make a milling machine with your own hands, but in some situations it will be much more convenient to purchase a professional model in a store. A homemade router will not be powerful enough, you will have to work intermittently. But for one-time use, it's a great option.

Using a drill

It's no secret that a drill can be used not only as a drill, but also as a multifunctional tool. There is a whole range of different devices that facilitate the work of the worker.

For example:

a cutter for metal for a drill avoids monotonous manual work with a file;
a scissor attachment for a drill provides the ability to cut metal sheets and elements;

The drill bit for cutting metal tiles, in turn, helps to accurately cut sheet metal roofs at any angle.

Working with this kit takes some skill, but over time you will realize the benefits of this method.

Let's take a closer look at each option.

For cutting tiles

Another name for this drill bit is cricket. The set can be used both for smooth surfaces and for profiled iron sheets. The advantage of this cutter is the ability to create an even cut, without burrs and irregularities.

The cricket drill attachment is convenient to use for:

cutting thin-sheet products;
cutting out parts from metal sheets.

Since its application does not depend on the spatial arrangement, you can easily cut a horizontal, and even vertical sheet.

Scissors attachment

Of all the nozzles presented, this one is the least similar to a drill. It turns the drill into an electric shear, not a nibbler. They work on the principle of a straight cut, cutting through metal with sharp edges using mechanical force. This is a rougher method for cutting metal and plastic. Such scissors perform only a straight cut; it is very difficult to change its direction during operation.

This set is more suitable for cordless tools.

Milling cutter

In another way, this nozzle is called a roller cutter. It is designed for processing wood and metal products:

a roller cutter replaces a file;
significantly speeds up the grinding process;
eliminates defects.

One set can include cones of different shapes, thus, for each specific situation, you can choose the most suitable nozzle. Some of them practically do not differ externally from the drill.

Tool design

According to the shape of the tooth, the cutters are divided into pointed and relief cutters. In pointed teeth, they have flat front and rear surfaces, while in recessed teeth, only the front surface is flat, while the back has the shape of an Archimedean spiral. Sharpening of pointed teeth is carried out on the flank surface and the size of the tool changes. Therefore, it is not recommended to sharpen them frequently. Re-ground teeth are sharpened on the front surface and can be reground multiple times.

Drill cutters can be produced in one piece or assembled. Solid ones are made from one piece. The material of the tool body and the cutting part is the same. The production of such products is more economical. The body of the assembled cutter is made from inexpensive steel grades, and carbide inserts are used for the cutting part. This makes the tool more expensive but improves performance.

Assembling the base for a homemade router from a drill

First, think over the design of the desktop and the layout of the router on it. You don't have to assemble a tabletop, but buy it in a specialized store, but it is quite expensive. For self-production, use the drawings. A good table will provide comfort and will speed up the process of the router. The base is a sheet of durable plastic or chipboard with a thickness of at least 12 cm. Plastic is not afraid of moisture, but it is faster and easier to make a tabletop from chipboard.

Note! There are other options: MDF or phenolic plastic. The table top is placed on the guides

Provide the possibility of their adjustment to adjust the position of the table for your convenience. Also note that the space near the work surface should be protected

This is important when working with a hand router. In addition, the parts need a clamping mechanism.

The table top is placed on the guides. Provide the possibility of their adjustment to adjust the position of the table for your convenience. Also note that the space near the work surface should be protected

This is important when working with a hand router. In addition, the parts need a clamping mechanism.

Helpful advice! Any holes in the countertop are cut with a conventional hand drill.

Installation of an adjusting lift:

Cut out a small panel from the chipboard and make 4 bars for it to support. The materials used must be durable and reliable.
On the countertop, cut a semicircular hole with a jigsaw or an electric hacker.
Make slots for the clips and thrust plate.
Attach the panel to the engine using bolts or special fasteners.

The milling cutter must be fixed on the table on the bearing units.
At the final stage of making the countertop, sand all its wooden surfaces with sandpaper. The work surface must be on a solid and durable base.

Structure and purpose

In simple words, the structure of the milling apparatus can be described as follows: the electric motor of the unit imparts rotation to the shaft on which the milling cutter is located (a specialized nozzle).

When installing a manual device, the cutter is placed in a special chuck, cam or collet.

The key task of the fixture is the processing of plastic, iron, wood, glass, ceramics or organic glass.

An example is the preparation of technological holes for a door lock in a wooden sheet.

In addition, it can be processing the edges of parts or cutting threads, milling cavities and grooves.

Rotation is provided by an electric motor operating from an alternating electric current network. A wide variety of nozzles can be used based on the material that needs to be processed.

The simplest material for milling is wood, therefore, in general, milling cutters for processing it will be especially common and inexpensive. For metals of different levels of strength and toughness, nozzles should be used that differ in their properties depending on the characteristics of the material being milled.

Of course, cutters for metals or wood are not suitable for processing ceramics or glass; for such materials, you need to choose a cutting tool with different parameters.
