It generally consists of abrasives, binder and porosity, and the three parts are called three elements of bonded abrasives. According to different classification of binder, it is commonly divided into ceramic (bond) grinding wheel, resin grinding wheel (bond) and rubber wheel (bond). Dosage of grinding wheel in abrasives tool is the largest and it is also the most widely used for various grinding, cutting and machining operations.
