PCD cutting tools system using a selection of diamond particles and carbide together through high pressure and high temperature sintering. PCD both hardness and wear resistance of natural diamond, have the toughness of cemented carbide, processing out of a high workpiece surface finish can be achieved with an auto-generation mill, greatly improved production efficiency, reduce costs, is an ideal new tool materials. PCD cutting tool because of its excellent machining quality and machining economics in the non-metallic materials, nonferrous metals and their alloys, metal matrix composites and other cutting areas shows that other tools can not match advantage. At present, PCD tool machining range from the traditional metal cutting extended to stone processing, wood processing, metal matrix composites, glass, engineering ceramics and other materials processing.
