Grinding wheel having synthetic resin layers covering axially opposite end faces of body of the wheel

摘要

A grinding wheel including (a) a cylindrical main body having a grinding surface on its outer circumferential surface, and (b) a pair of synthetic resin layers disposed on respective axially opposite end faces of the cylindrical main body. Each of the synthetic resin layers covers at least a radially outer end portion of a corresponding one of the axially opposite end faces. The cylindrical main body has an abrasive layer which constitutes a radially outermost layer thereof so that the abrasive layer provides the grinding surface.
