Grinding wheel is the most important type of grinding tool in grinding. The grinding wheel is a porous body that is prepared by adding a binder to the abrasive, pressing, drying and calcining. Due to different abrasives, binders and manufacturing processes, the characteristics of the wheel vary greatly, which has a major influence on the processing quality, productivity and economics of grinding. The characteristics of the wheel are mainly determined by factors such as abrasive, particle size, binder, hardness, structure, shape and size.
