摘要：A grinding wheel having a circular outer periphery, and a working front end facefor grinding a roll as installed in place on a rolling mill or other equipment, such that thefront end face is held in pressed frictionally sliding contact with an outer circumferentialsurface of the roll. The wheel has an annular first abrasive member, and one or twoannular second abrasive member(s) which is/are formed integrally with the first abrasivemember, and disposed on corresponding at least one of the radially outward and inwardsides of the first abrasive member. Each second abrasive member comprises a bondingagent different from that of the first abrasive member, and has a lower modulus ofelasticity than the first abrasive member. Also disclosed is a grinding wheel which has asingle abrasive body whose outer and/or inner circumferential surface(s) is/are taperedsuch that the radial wall thickness decreases in an axial direction toward the working endface. The abrasive body may preferably contain short glass, carbon or alumina fibers.
