PCD is polycrystalline diamond which is manufactured by sintering together carefully selected diamond particles.This is done at a very high temperature and pressure in the presence of a solvent/catalyst metal.The results are an extremely tough inter grown mass of randomly orientated diamond crystals. These are then bonded to a tungsten carbide substrate.This is why PCD, can be regarded as a composite material.PCD combines the hardness, abrasion resistance and high thermal conductivity of diamond; with the toughness of tungsten carbide.PCD tooling can replace existing cutting tool materials such as HSS or Tungsten Carbide when applied correctly.In turn reducing tool costs per component through extended tool life and production downtime.At Prima Tooling Ltd we only use SYNDITE PCD from Element 6. We cut the discs ourselves into a variety of shapes and sizes, for use on our tooling. As SYNDITE is the only PCD tool material manufactured in discs of up to 74mm maximum diameter. This Enables us to manufacture tools which require a long, continuous cutting edge.SYNDITE is available in 3 standard grades - 002, 010 and 0.25 (equivalent to 2, 10 and 25 microns average diamond grain size).PCD Tooling has many applications and can be used on a variety of materials such as:Aluminium and its alloys Copper and its alloys Precious steels Plastic Graphites and graphite composites Green ceramics and carbides Composite materials Carbon Fibre FibreglassUsing the correct grade of PCD, means that an excellent surface finish can be achieved, on otherwise difficult to machine materials.
