The study of dry grinding of steel cams using cubic boron nirtride tools

Experimental studies that simulate grinding of hardened alloyed steel cams have demonstrated that these workpieces can be machined with a minimum work surface heating by using highly porous cubic boron nitride wheels with the oil mist cooling or without cooling. It has been found out that for minimizing the thermodynamic stress level in the dry grinding mode it is advisable to preset machining conditions with maximum possible depth of cut and minimum workpiece rotational speed.
