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.
