Tips for Using a Tungsten Carbide Burr

#Tungstencarbideburr is a popular tool for metalworking, deburring, rust-removing, cleaning, and other applications. There are tips that you need to pay special attention to when using them.

Operating Instructions

Carbide rotary files are mainly driven by electric tools or pneumatic tools (can also be installed on machine tools). The rotation speed is generally 6000-40000 rpm. When using, the tool needs to be clamped and straightened, and the cutting direction should be from right to left. Move evenly and do not cut back and forth. At the same time, do not use excessive force. To prevent chips from flying around during work, please wear protective glasses.

Since the rotary file must be installed on the grinding machine and controlled manually during operation, the pressure and feed speed of the file are determined by 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, it is important to emphasize the following: 

1. Avoid applying too much pressure when the speed of the grinder decreases. This will cause the file to overheat and become dull easily; 

2. Try to make the tool contact the workpiece as much as possible because more cutting edges can penetrate into the workpiece and the processing effect will be better;

3. Avoid filing the handle part Do not touch the workpiece as this will overheat the file and can damage or even destroy the brazed joint.

It is necessary to promptly replace or re-sharpen the blunt file head to prevent it from being completely destroyed. A dull file head cuts very slowly, so the pressure on the grinder has to be increased to increase the speed. This will inevitably cause damage to the file and grinder, and the cost is much greater than replacement or re-sharpening. The cost of the file head.

Lubricants can be used during operation. Liquid wax lubricants and synthetic lubricants are more effective. The lubricant can be added to the file head regularly.

Grinding speed selection

High operating speeds are important for the efficient and economical use of round file heads. Higher operating speeds are also helpful in reducing chip accumulation in file grooves and are also more conducive to cutting corners of the workpiece and reducing the possibility of cutting interference or wedge deviation. However, this also increases the likelihood of the file handle breaking.

Carbide burrs 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: a 30,000-rpm grinder can choose files with a diameter of 3/16" to 3/8"; a 22,000-rpm grinder can choose a file with a diameter of 1/4" to 1/2". But for more efficient operation, it is best to choose a diameter that is most commonly used. In addition, maintenance of the grinding environment and system is also very important. If a 22,000-rpm grinder breaks down frequently, it may be because it has too few rpm. Therefore, we recommend that you always check the air pressure system and sealing device of the grinder.

Reasonable operating speed is indeed very important to achieve the required cutting degree and workpiece quality. Increasing the speed can improve the processing quality and extend the tool life, but it may cause the file handle to break. Lowering the speed helps to remove material quickly, but it may cause the system to overheat and the cutting quality to fluctuate. Each type of rotary file requires an appropriate operating speed for the specific operation.
