Title: Method for improving surface finish of workpieces ground with abrasive wheels

Abstract: The surface finishes of workpieces ground with cubic boron nitride, diamond or similar grinding wheels is improved by applying a lapping composition comprising a multiplicity of fine grit abrasive particles dispersed in a normally solid but friction-meltable organic polymeric matrix against the rotating wheel, during spark out, and causing the lapping composition to melt and form a layer on the surface of the wheel and applying the lapping layer against the workpiece until the desired surface finish is achieved.
