PCD(Poly Crystal Diamond) refers to diamond particles which have been sintered together with a binder phase under high pressure, high temperature conditions similar to those used in single crystal diamond synthesis. These sintered PCD materials have a variety of uses, most notably for cutting tools, machining non-ferrous metals, non-metallic materials and wear parts.
As cutting tool material, PCD is generally recommended for the machining non ferrous workpiece which high abrasion resistance is required.
