CLASSIFICATION OF CBN & PCD GRADES

FEATURES

NON-COATED CBN MATERIALS

CBN sintered materials base cutting tools are produced by binding CBN (Cubic Boron Nitride) and ceramic having hardness next to diamond and sintering under ultra-high pressure and high temperature. CBN has lower affinity to iron than diamond. The low affinity and high hardness properties means that sintered CBN delivers a B superior cutting performance especially during high speed machining of materials such hardened steel, cast iron and sintered alloys etc.

COATED CBN MATERIALS

To achieve longer tool life, Mitsubishi uses a unique "Particle-activated Sintering Method", combined with increased cutting edge strength. With high crater wear resistance CBN grades and a wear resistant ceramic coatings, longer tool life and improved machine efficiency are obtained.

PCD MATERIALS (Sintered Diamond)

Suitable for cutting materials such as nonferrous metals and fiber reinforced plastics (FRP) including aluminum alloys. It supports ultra high speed finish cutting.
