The best operation speed for carbide burr is 6000-40000 rpm?

Operating speed instructions


carbide burr is mainly driven by electric tools or pneumatic tools (can also be installed on the machine tool), the speed is generally 6000-40000 rpm, the tool needs to be clamped and clamped in use, and the cutting direction should be from right to left Move evenly, do not cut back and forth, and do not use excessive force at the same time, to prevent the cutting from scattering during work, please use protective glasses.

Because the carbide burr is embedded in the grinding machine during operation and is manually controlled; the pressure and feed speed of the file depend on the working conditions and the experience and skills of the operator. Although a skilled operator can control the pressure and feed speed within a reasonable range, here is still to be emphasized: first, avoid applying too much pressure when the speed of the grinder is reduced, This will cause the file to overheat and become blunt; secondly, make the tool as much as possible in contact with the workpiece, because more cutting edges can penetrate the workpiece, and the processing effect can be better; finally, the filehandle part should be avoided contact with the workpiece, as this will overheat the file and damage or even destroy the brazed joint.

Replace or sharpen the blunt file head in time to prevent it from being completely destroyed. Blunt file heads are slow to cut, so the pressure of the grinder must be increased to increase the speed, and this will inevitably cause damage to the file and the grinder, and the cost of the loss is much greater than the replacement or heavy sharp The cost of the file head.

Lubricants can be used in conjunction with the operation. Liquid wax lubricants and synthetic lubricants are more effective. The lubricants can be added to the file periodically.


Selection of operating speed

Higher operating speed is very important for the effective and economical use of round file heads. The higher running speed is also very helpful to reduce the chip accumulation of the file groove, and it also helps to cut the corner of the workpiece and reduces the possibility of cutting interference or wedge deviation. However, this also increases the possibility of filehandle breaking.

carbide burr should run at 1,500 to 3,000 surface feet per minute. According to this standard, there are many types of rotary files for grinders to choose from. For example, 30,000-revolution grinders can choose files with diameters from 3/16 “to 3/8”; 22,000-revolution grinders can choose files with diameters from 1/4 “to 1/2”. But for a more efficient operation, it is best to choose the most commonly used diameter. In addition, the maintenance of the grinding environment and system is also very important. Assuming that a 22,000-revolution grinder often fails, it may be due to too few revolutions. Therefore, we recommend that you always check the air compressor system and sealing device of the grinder.

Reasonable running speed is indeed very important to achieve the required cutting degree and workpiece quality. Increasing the speed can improve the processing quality and prolong the life of the tool, but may cause the filehandle to break; reducing the speed helps to quickly remove the material, but may cause the system to overheat and the cutting quality to fluctuate. Each type of rotary file must select the appropriate running speed according to the specific operation.
