SE Cemented Carbide Rotary Burrs Blank

Rotary Burrs mainly for electric tools or pneumatic tools drive (also can be installed on the machine), rotating speed of 6000-40000 rpm, the need to use the tool clamping, clamping, cutting direction from right to left uniform movement, not reciprocating cutting at the same time, not too much force, to prevent cutting flying work, please use protective glasses.
Because the rotary files should be embedded on the lapping machine and manually controlled, so the pressure and speed of the file must be determined by the working conditions and the experience and skills of the operators. Although a skilled operator can be pressure and feed speed control in a reasonable range, but here is to emphasize that: first, to avoid in the grinding machine speed becomes small under the condition of adding too much force that will enable the file to be blunt, with overheating; second, make as far as possible the maximum degree of tool workpiece contact, because more cutting edge can penetrate the workpiece processing effect can be better; finally, to avoid the file handle part comes into contact with the workpiece, because it will make the file and overheating, can damage or even destroy the brazing joint.
Replace or sharpen the blunt file in time in order to prevent its thorough destruction. The blunt file is cut very slowly, so it has to increase the pressure of the grinding machine to raise the speed, which will cause damage to the file and lapping machine, and the cost is much greater than the cost of replacing or re sharpening the file.
The lubricant can be used in conjunction with the lubricant, liquid wax lubricants and synthetic lubricants are more effective. The lubricants can be regularly dripped to the file head.
Selection of grinding speed
High speed is very important for effective and economical use of a head. The higher running speed is also helpful for reducing the chip assembly of the file grooves, and at the same time, it is also helpful for cutting corners of workpiece and reducing the possibility of cutting interference or wedge deflection. However, this will also increase the possibility of the fracture of the file handle.
Cemented Carbide Rotary Burrs should run at 1500 to 3000 feet per minute. According to this standard, there are many kinds of rotary files for grinding machine choice. For example, the 30000- rotary grinding machine can select a file with a diameter of 3/16 "to 3/8", and the grinding machine for the 22000- rotation can select a file with a diameter of 1/4 to 1/2. But for more effective operations, it is best to choose the most commonly used diameter. In addition, it is also very important for the grinding environment and the maintenance of the system. It is assumed that a 22000- rotary grinding machine often fails, which may be the cause of too little change. So we suggest that you often check the air pressure system and the sealing device of the grinder.
The reasonable running speed is very important to the required cutting degree and the quality of the workpiece. Increase the speed can improve the machining quality, prolong tool life, but may cause the file handle fault; reduce speed helps to quickly remove the material, but may cause system overheating and cutting quality fluctuations ills. Each type of rotary file should choose the appropriate running speed according to the specific operation
