CBN & PCD TURNING INSERTS CBN & PCD TURNING INSERTS COATED CBN BC8100 series for machining of hardened steel FEATURES The coated CBN grade BC8100 series and non-coated CBN grade MB8100 series for cutting of hardened steel uses newly developed optimized substrate technology CBN base material. The new ultra-micro-binder prevents sudden fracturing and longer tool life. The BC8100 series coating exhibits excellent fracture resistance and wear resistance by using a special PVD coating B suitable for each cutting mode. y Newly Developed Special PVD Coating BC8105 BC8110 BC8120 BC8130 CrAlN-base Coating TiAlSiN-base Coating AlCrN-base Coating TiAlN-base Coating TiAlN-base Coating TiAlN-base Coating TiAlN-base Coating CBN Sintered Body CBN Sintered Body CBN Sintered Body CBN Sintered Body Offers excellent surface Chipping caused by built Chipping caused by built Peeling caused by severe finishes. up edge is prevented with up edge is prevented with impact and chipping are Peeling resistance and improved welding resistance. improved welding resistance. prevented with high fracture adhesion strength are improved Improved wear and adhesion Improved adhesion to the resistances. by having both lubricity and strength to the CBN surface. coating to the CBN surface Improved adhesion strength to wear resistance. enhances peeling resistance. the CBN surface.
