1. Please check carefully before installing the cutting wheel to confirm whether the cutting wheel is deformed, cracked or collapsed. 2. When the flange is too small or the precision is poor, the fiber cutting disc Chinese supplier is easily damaged. Please use it after improvement. 3. When the cutting wheel is marked with the direction of rotation, it must be in the same direction as the machine. On the contrary, the cutting is not sharp and it is difficult to perform the performance of the cutting wheel. 4. If a cutting wheel that does not match the cut workpiece is used, it is prone to abnormal wear, poor sharpness, abnormal heat, and the like. 5. If an abnormality is found during the cutting process, stop immediately. 6. When the cutting is not sharp, the grinding wheel should be trimmed. If it continues to be used, it will cause overheating and overloading and damage the grinding wheel. 7. In the rotation of the grinding wheel, it is strictly forbidden to cut by hand, and it is not allowed to touch the grinding wheel by hand or body. 8. The cutting wheel is strictly prohibited for operations other than grooving or cutting, to avoid abnormalities due to uneven force. 9. The surface quality and cutting performance of the workpiece are mainly related to the abrasive grain size of the durable cutting off wheel. The finer the particle size, the better the surface finish. At the same time, it is also related to the workpiece material, hardness, cutting amount, machine tool conditions, processing requirements and other factors. 10. The ultra-thin cutting wheel has been shaped and edged before leaving the factory and can be used directly by the user. If the user needs further shaping, it is recommended to use green silicon carbide or white corundum whetstone. The particle size is larger than the size of the cutting wheel. If the user needs to further sharpen or use a section of the blade, it is recommended to use green silicon carbide or white corundum. Whetstone, the size of the cutting wheel is finer than the size of the cutting wheel 1-2 or the same number.
