CLASSES DE CBN E PCD

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 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 aluminium alloys. It supports ultra high speed finish cutting.

Work materials for turning grades/application area

Hardened Steel

Suitable for finishing with surface roughness Ra 0.6 μm or Rz 2.4 μm or less.

Coated CBN Grade BC8100 and Non-coated CBN Grade MB8100 for high-hardness steel processing are available in a wide range of areas from finishing to continuous cutting of hardened steels and strongly interrupted machining.

Sintered Alloy

The CBN grade “MB4120” for sintered alloy and cast iron cutting can be used widely from continuous cutting to interrupted cutting in the processing of cast irons such as sintered alloys for valve mechanism parts and oil pump parts.

Cast Iron

Lineup of grades available from general cutting to deep depth cutting for high efficiency machining.

Aluminium Alloy

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