Moresuperhard recommends ceramic bond diamond grinding wheels for the rough grinding of the cylindrical surface of the diamond layer on PDC cutters. These wheels demonstrate excellent efficiency and cost-effectiveness compared to traditional resin bond wheels.
PCD tools offer excellent hardness and wear resistance for machining difficult materials, but grinding them poses unique challenges. This article explores common issues such as chipping, high surface roughness, dimensional deviations, burning, and grinding wheel wear. Learn practical solutions to optimize grinding parameters, wheel selection, and machine accuracy to improve tool life and reduce costs.
