PCD BLANKS FOR CUTTING TOOLINGS
DQ Diamond produce the top quality pcd cutting tool blanks with state of art production facilities. We have large diameter of hydraulic press machine for sintering process, pcd laser cutting equipment, EDM cutting machines, C-scan ultra-sonic scanning equipment for cutting and inspection process etc. PCD blanks/ plates/pads are widely used for the machining of non-ferrous metals and alloys, such as aluminum, copper, aluminum / gray iron composites, as well as nonmetallic materials such as wood, chipboard, ceramic，plastic, rubber etc, where high abrasion resistance and good surface finish are required. The products are available in 2µm，5µm, 10 µm, 20µm，25µm，and 2+25µm etc.
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 used 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
