[0002] Grinding wheel is also called bonded abrasive tool. Grinding wheel is a bonded abrasive tool with a certain strength that is formed by bonding ordinary abrasive into a certain shape (mostly round with a through hole in the center). It is generally composed of abrasive, bond and pores. These three parts are often called the three elements of bonded abrasive tool. According to the different classifications of bond, common ones are ceramic (bond) grinding wheel, resin (bond) grinding wheel and rubber (bond) grinding wheel. Grinding wheel is the most widely used abrasive tool. It rotates at high speed when used and can perform rough grinding, semi-fine grinding and fine grinding, as well as grooving and cutting on the outer circle, inner circle, plane and various surfaces of metal or non-metal workpieces.
