1. Check carefully before cutting the grinding wheel to confirm whether there is deformation, cracks or collapse.
2. When the flange is too small or the precision is poor, it is easy to damage the cutting wheel. Please use it after improvement.
3. When marking the rotation direction of the cutting wheel, it must be consistent with the rotation direction of the machine tool. On the contrary, the cutting is not sharp, and it is difficult to exert the performance of the cutting wheel.
4. If the cutting wheel does not match the piece to be cut, it is easy to cause abnormal wear, poor sharpness, abnormal heat, etc.
5. During the cutting process, if any abnormality is found, the machine should be stopped immediately.
6. When the grinding wheel is not allowed to cut by hand, it is not allowed to touch the grinding wheel with your hands and body.
7. The cutting wheel is strictly prohibited from cutting or cutting off external operations to avoid abnormality caused by uneven force.
8. When the cutting is not sharp, the grinding wheel must be trimmed and opened. If you continue to use it, it will overheat and overload and damage the grinding wheel.
