CBN & PCD TURNING INSERTS Cutting Speed vc (SFM) BC8105 BC8110 Cutting Speed vc (SFM) BC8120 BC8130 MB8110 MB8120 MB8130 Cutting Speed vc (SFM) CBN & PCD TURNING INSERTS 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 alloysetc. 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. y Work Materials for Turning Grades/Application Area aHardened Materials ISO COATED CBN SERIES NON-COATEDCBN SERIES 10 H 20 30 COATED CBN MATERIALS NON-COATED CBN MATERIALS High 1150 1150 1150 BC8105 BC8110 820 820 820 MB8110 BC8120 490 490 490 MB8120 BC8130 MB8130 165 165 165 Low .002 .004 .006Feed f (IPR) Continuous cutting Light interrupted cutting Medium interruptedcuttingHeavy interruptedcutting Continuous cutting Medium interrupted cutting Heavy interrupted cutting Suitable for finishing with surface roughness Ra .024 μinch or Rz .094 μinch 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.
