Product Description

Polycrystalline Diamond (PCD) is a synthetic diamond product that is produced by sintering together selected diamond particles with a metal matrix using sophisticated technology. The diamond and matrix, when sintered together under high temperatures and pressures, creates a PCD tool blank that is high in uniform hardness and is abrasive resistant in all areas.
Features compared with tungsten carbide tools:
1, The hardness of PCD is *0 to **0 times that of tungsten carbide.
2. The thermal conductivity of PCD is 1.5 to 9 times that of tungsten carbide.Its thermal conductivity is  **0W/mk. The PCD blank can conduct heat fast
3,  PCD toolings life can exceed carbide cutting tool life *0 to **0 times. Features compared with natural diamond tools:
1, PCD is more resistant over natural diamond because of its random orientation structure of the diamond particles, and is backed by a carbide substrate. 
2, PCD is more constant in wear due to complete production system for quality consistant control, Natural diamond is a single crystal in nature and has soft and hard grains both,when making into toolings, it will not be well using with soft grains.
3, PCD is cheaper and with various shapes and sizes to choose from for toolings, natural diamond is the limit on these point. Application:
The PCD blank is userd in many different fields including aviation, the car industry, electronics,and the wood and stone industry. It applies to varous materials such as nonferrous metal, tungsten carbide, ceramic, nonmetal and composite material. Materials recommended for cutting with PCD:
 Epoxy resins
 Gold and silver
 Ceramics, unfired
 Plastics and rubber
 Carbon and graphite
 Graphite composites
 Fiberglass composites
 Chipboard and fibreboard
 Zinc and magnesium alloys
 Aluminum and aluminum alloys
 Copper, brass and bronze alloys
 Tungsten carbide, presintered and sintered
