PCD Blanks, PCD Tips

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 directions.

Features compared with tungsten carbide tools:
1, The hardness of PCD is 80 to 120 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 700W/mk. The PCD blank can conduct heat fast
3, PCD toolings life can exceed carbide cutting tool life 50 to 100 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
