Description

[0002] Grinding wheel, also known as bonded abrasive, is a bonded abrasive with a certain strength and ordinary abrasives are bonded into a certain shape by a binder. It is composed of abrasives, binders and pores. Grinding wheel is the most widely used abrasive. It rotates at high speed when in use and can perform rough grinding, semi-finishing 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.
