[0002] A grinding wheel is a main type of abrasive tool in grinding processing. When in use, the grinding wheel rotates at a high speed, and can perform rough grinding, semi-precision grinding, precision grinding, grooving and cutting operations on the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces. Therefore, grinding wheels are widely used in the field of machining.
