ABSTRACT:
A vitreous bonded cubic boron nitride grinding wheel is provided which optionally contains silicon carbide or other abrasive having a coefficient of thermal expansion substantially the same as the coefficient of thermal expansion of cubic boron nitride, and wherein the vitreous bond, having a coefficient of thermal expansion substantially the same as the coefficient of thermal expansion of cubic boron nitride, is substantially non-reactive with cubic boron nitride and the optional abrasive.
