PCD

Polycrystalline Diamond (PCD), is a synthetic diamond product that is produced by sintering selected diamond particles with a metal matrix using very sophisticated temperature and high pressure technology.
PCD by its nature, is high in uniform hardness, and also more abrasive and shock resistant in all directions than natural diamonds because of its random-oriented structure of the diamond particles.

CVD

  • Similar to natural diamond
  • Colorless
  • Superior edge quality for ultra precision machining applications
  • Highly consistent material properties

PBCN

Polycrystalline cubic boron nitride (PCBN) is an artificially synthesized material. Except for diamond, PCBN is the hardest material. however, unlike diamond, PCBN is stable under conditions of high temperature (up to 1000°c), normally seen when machining hardened ferrous or super alloy materials. PCBN tools permit metal cutting with feed and speed rates that are much higher than conventional cutting tools.
