17719947765Man-made polycrystalline diamond compact tool (PCD) is a superhard tool developed in the 1960s. It has hardness and wear resistance second only to natural diamond, low friction coefficient, high thermal conductivity, low linear expansion coefficient and high composite bending strength, and is used in high-speed cutting of various non-ferrous metals and non-metals. Its tool durability is tens to hundreds of times that of cemented carbide. my country successfully developed synthetic diamond in the 1960s. On this basis, a layer of polycrystalline diamond is sintered on the cemented carbide substrate by high temperature and high pressure technology, and the two are formed into an integrated cutter blank. This combines the high hardness and wear resistance of diamond with the toughness of cemented carbide. This kind of blade is called synthetic polycrystalline diamond compact, or PCD for short.
PCD tools are mainly used for efficient cutting of non-ferrous metals and non-metals. Such as aluminum and aluminum alloys, copper and copper alloys, cemented carbides, engineering ceramics, graphite, plastics, rubber, laminates, silicone rubber, babbitt alloys, various composite materials, glass fiber reinforced plastics, etc. Especially in the automobile manufacturing, aerospace, aviation, shipbuilding, engine manufacturing industries, it can be widely used.
