Genera use of CBN in tool grinding: Technology and economics

A long term test program in which all the grinding processes technically capable of being converted from conventional abrasives to crystalline boron nitrides (CBN) was carried out in close cooperation with an abrasives manufacturer and a tool manufacturer whose production included all types of cutters; notably, hobs, profile cutters, side melting cutters, and face milling cutters, as well as crushing rolls for profiling grinding wheels. The material mainly used was EM05C05 confirming to S 6-5-2-5.
