[0002] The grinding wheel is the most important type of grinding tool in grinding processing. The grinding wheel is a porous body made by adding a binder to abrasives and then undergoing compacting, drying, and roasting. Due to different abrasives, binders, and manufacturing processes, the characteristics of grinding wheels vary greatly, so they have an important impact on the processing quality, productivity, and economy of grinding.
