[0002] A grinding wheel is a tool used for grinding, lapping, and polishing. When the grinding wheel rotates at high speed, the abrasive particles come into contact with the surface of the material being processed. By utilizing the hardness and sharpness of the abrasive particles, the excess material on the surface of the material being processed is removed through cutting and frictional mechanical action, thereby achieving the purpose of grinding, lapping, or polishing.
