Manufacturers combine technologies to meet growing demand for PCD tooling

摘要

Cutting-edge geometries and final dimensions of cutting tools are typically produced on CNC tool and cutter grinders. However, tooling with polycrystailine diamond (PCD) cutting edges, used increasingly in processing aerospace grade materials and carbon-fibre components, poses a problem. Grinding PCD pits the hardest known substance to man (diamond) against an equally hard grinding wheel - consuming both time and grinding wheels.
