CNC with rotary spindle for wood. CNC milling machines with rotary spindle

Spindle, is the most important structural element of such equipment. The cutting tool is fixed in this part, and it is she who transmits rotation to it.

Spindle options for milling machine

Engraver

If you are interested in the most inexpensive spindle for your homemade one, then you can use a serial engraver for this. The power of such a device is 125 W, and the price starts from 500 rubles. However, such a spindle has a number of significant disadvantages. At low speeds, it produces a weak torque, which does not allow it to be used for processing metal blanks. In this regard, such a spindle can only be used for engraving and for processing blanks made of soft wood with small diameter cutters.

Bormashinka

The second version of the do-it-yourself CNC spindle is a drill, the cost of which starts from 2000 rubles. Compared to an engraver, such a device works much quieter, loses little torque at low speeds, and is distinguished by a high-quality cartridge clamp.

DC motor

The spindle of the milling machine can be made by hand using DC motors operating on a voltage of 12–48 V. The power of such motors, capable of developing 12,000 revolutions per minute, is 400 watts. Such a spindle motor has the following advantages: the absence of strong runout and strong noise during operation, the use of a standard ER11A collet.

If you equip such a spindle with a simple electronic device, then with the help of the CNC you can control the number of its revolutions. Such a spindle also has disadvantages, which include the need for additional source power supply, low power, significant heating during operation, which necessitates its cooling. Due to the low power with such a spindle, it is suitable for processing only soft materials.

Router and straight grinder

As a spindle for homemade CNC machines, you can also use straight grinders and milling machines. If you take the Enkor FME-850 W milling cutter as a spindle, then you will have a machine at your disposal that can process not only wooden blanks, but also plywood and non-ferrous metal products. Conveniently, this router comes with a 6 mm collet, for which there are standard 3 to 6 mm adapters. Using this adapter, milling cutters with diameters of 0.1–6 mm can be installed in such a spindle.

Not all models of milling cutters have such a collet in their kit, which does not allow them to be used for CNC equipment. The milling cutter Enkor FME-850 W also has disadvantages, which include high noise during operation and the absence in the design of an electronic device responsible for changing the number of revolutions, which does not allow it to be used for processing polymer materials(this requires a small speed of the milling cutter).

Fraser Sparky

If it is necessary to process polymeric materials on a CNC milling machine that you made with your own hands, then it is better to use milling cutters as a spindle for it. trademark Sparky. The power of such milling cutters can vary between 500-1050 watts. The design of models whose power starts from 750 W has an electronic device responsible for changing the number of revolutions, so they can be used for processing polymeric materials (acrylic, PVC, double-sided plastic, modeling plastic, etc.). To process such materials, the router must be able to rotate at a low number of revolutions without losing its power. This prevents heating in the processing zone and melting of the plastic, and high power ensures sufficient productivity of the milling process.

Milling cutter Kress

Optimal in terms of price-quality ratio are Kress brand milling machines, which can also be used as spindles for machines equipped with a CNC system. The big advantage of such milling cutters is that their design includes a system that normalizes runout.

Professional spindle

If desired, you can equip your homemade milling machine with CNC professional spindle, the design of which provides for a liquid cooling system. In addition to an efficient cooling system, the design of such a spindle has 3-4 bearings, which significantly increases its reliability and processing accuracy (here it is worth noting that in conventional spindles household equipment only 2 bearings installed). The advantages of such devices include the absence of wearing brushes in their design and the low noise level during operation. The biggest disadvantage of such spindles is that their cost starts from 7000 rubles. In addition, you will additionally have to spend money on purchasing a frequency converter for the cooling system, which costs about 6,000 rubles.

DIY CNC spindle

Most often, for do-it-yourself CNC machines, they use a Dremel metal cutting device or Chinese analogues of similar equipment, which can be purchased without any problems in any city in the Russian Federation.

Meanwhile, it is not entirely correct to use such devices as a milling machine spindle, since they become unusable very quickly. The thing is that only one thrust bearing is provided in their design, which does not allow them to perceive lateral loads typical for milling for a long time.

Almost any technological operation for milling wood and metal is carried out with lateral loads on the cutting tool and, accordingly, on the spindle structure.

Very often, for home-made milling machines, spindles are purchased in which collector motors are installed. Such devices are inexpensive and work well at high speeds, and at low speeds they lose their power significantly. These problems can be avoided if you install a spindle with a brushless motor on your machine.

As a ready-made basis, you can use an inexpensive CNC milling machine, and to make a spindle for it with your own hands, you will need the following components:

• brushless motor (NTM series 50-50 580 KV/2000 W);
• extended shaft;
• controller for brushless motor;
• servo tester.

The servo tester, which is needed to adjust the spindle speed, can be purchased at the most inexpensive. It is only important to pay attention to the convenience of attaching such a device to the CNC milling machine itself.

The elongated shaft of such an engine allows you to fix the cutter directly on it using a collet clamp. To do this, two bearings are mounted on the motor shaft by means of holders, and the motor itself also has two built-in rolling bearings. The structure assembled in this way perfectly resists the lateral loads that occur when milling on the machine not only metal, but also softwood blanks.

An increase in the size of the machine frame provides for the size of the workpiece plus the technological movement of the milling spindle rotated by 90 ° to process the entire perimeter in the area of ​​processing cavities at the ends of the parts for installing fittings. Suckers are set as close as possible to the corners of the products, taking into account the already applied relief pattern. Traverses are evenly fixed along the long side of the part, suction cups are attached evenly along the edges. The machining program contains the replacement and positioning of cutters. The execution of the program for one side ends with the stop of the spindle and the information on the display. The operator turns the part over and fixes it. Starts the second side processing program.

If the part is made of solid wood, plastic, it is sent for grinding, painting and varnishing. If from MDF, it is sent for painting or laminating.

Replacing the tool used according to the program allows you to get a complete part in two installations ready product, processed from all six sides of the sides of an arbitrary contour.

The high quality of deep embossed surface treatment is achieved by using an end mill with a tip radius of about 1 mm, which in turn requires a large number of tool passes with a step of no more than 1 mm. The total machining time thus varies depending on the tool nose radius.

CNC milling machines with a rotary spindle are equipment designed for precise and high-quality material processing. The spindle is one of the most important elements of the device, allowing it to perform its task smoothly. This part is used to secure the cutting tool. It provides it with rotational functions, and improves performance.

Design and features

Spinel is available in the design of any machine designed for milling metal and wood. produced in the form of a rotating shaft. The cutter receives rotational movements from the spindle, due to which the device functions properly.

The main tool of the machine, which performs the main work, is associated with the state of the spindle. Without it, it will not work well. Using a milling machine, you should know not only the purpose of the spindle, but also the design of the rotary system. In the event of a malfunction of this part, it is not recommended to use the device.

The device is connected to the general design of the machine. The number of transmitted revolutions is regulated by the speed device. The quality and accuracy of milling work depends on how vibration resistant the brushless motor is. Regardless of whether the CNC machine was made at the factory or with your own hands, a special movable portal is provided for installing the spindle.

This part of the configuration is responsible for moving the element. The movement is carried out by:

• table axes for machine installation;
• in depth along the z-axis.

The machine cutter receives movement due to the presence of a special unit. The spindle minimizes the possibility of distortion, increasing the accuracy of production.

Classification

Due to the large number of spindle models, there are several types of classification. The most common type is the classification technical specifications. By purpose, they are divided into:

• CNC machines with two spindles designed for milling;
• vertically rotary elements for manual processing of products having a complex shape;
• rotary spindle of electric type (can be made by one's own efforts);
• vertically rotary elements of an electric type (made by hand, but have low productivity);
• element for working with the end part.

Depending on the application, there are several most commonly used spindles. One of these devices is an engraver. It has a low cost, but is installed on a do-it-yourself machine. The disadvantage of this device is the complex processing of metal products. The reason for the lack of low torque. Therefore, the engraver is recommended for processing soft wood.

Bormashinka

More expensive spindle option. Unlike an engraver, torque is maintained regardless of RPM. The advantage of this option is the cartridge clip, which is of high quality. The drill is characteristic quiet sound work.

DC motor

High performance device. In the process of work, it does not create a strong beat and loud sounds. Milling machines for such a device are easy to do with your own hands. The presence of CNC allows you to adjust the number of revolutions. The disadvantage of the unit is the rapid heating during the processing of the material. Periodically, the device should be cooled down. Recommended for use on soft workpieces.

straight grinder

Equipment capable of performing the tasks of a spindle. The device has high performance and is able to cope not only with wood, but also with metal. The disadvantage of the unit is high level noise during operation. The number of revolutions cannot be adjusted, since the package does not include an electronic device that performs this task.

Fraser Sparky

A milling element capable of being used as a rotary spindle. Not all routers can be used for this purpose. But the devices of this brand have high power, speed control and performance. These advantages are enough to operate the device for processing different materials. During operation, the parts heat up slowly, so safety and low risk of fire are ensured.

Milling cutter Kress

Another milling element with high quality at affordable price. Devices are used in conjunction with CNC systems. The package is equipped with an additional system to ensure a stable beat.

Professional spindle

An element designed specifically for the milling machine. The unit is liquid cooled. It is characterized by a high level of reliability and accuracy. During operation, the device does not create loud sounds. The disadvantage of the equipment is the high cost. The cooling system must be equipped with a frequency converter, which costs almost as much as the machine itself.

Advantages

The use of spindles provides the machine with a number of advantages:

• increases efficiency when using a working unit;
• enhances the strength of the equipment;
• improves instrument performance in processing.

High-strength materials are used for the manufacture of spindles, capable of withstanding heavy loads. The magnetic elements that are part of the unit configuration are practically not demagnetized.

The element cooling system is carried out by two methods:

• air;
• water.

The air system is more in demand and inexpensive. But it often fails due to clogging. Clogging occurs when the machine is used to process wood. This material creates a lot of dust that clogs the engine filter. It is recommended to work with the device after cleaning the filter. If cleaning is not done in a timely manner, repairs may be required.

Features of choice

The most common tools on the market are spindles made in Italy and China. The equipment is characterized not only by differences in quality, but also in design.

Equipped with a solid cylindrical body. To close the end parts, special covers are designed. To support the shaft, they have bearing assemblies. The equipment is rigid and has a low vibration rate. The design is reliably protected from pollution. The device has a more compact size and low price than its counterparts with the same power.

Flaw Chinese equipment has a high marriage rate. In the event of a bearing failure, it is difficult to replace them. In the presence of water cooling, the equipment gradually rusts.

Italian devices are considered to be of higher quality than Chinese ones. But their cost is much higher. Distinctive feature complete set are bearing knots of high firmness. They ensure the performance and quality of the units. Italian devices are characterized by smooth rotation and low beat rate. They are equipped with air cooling, so the design does not rust.

Service

Before using the equipment, it is necessary to warm up. Before turning off the unit, it must cool down. Bearing units should be periodically cleaned from contamination. Cleaning must also be carried out for the cooling system. Cooling fluid is used to service water cooling. It is recommended by the manufacturer for certain models. Rotor bearings require periodic replacement.
