CBN Tools H K PM S SUMIBORON series New generation Sumiboron inserts – an even better way to machine hardened steels - General Building on its global success machining hardened steels with Sumiboron inserts the addition of heat and wear resistant coatings to a variety of tough new CBN substrates has resulted in a new generation of high performance grades. With economy in mind the new inserts are multi cornered. Choose the coated insert suitable for your application and take your hard part machining operations to the new industry standard. - Types and application Hardness(Hv) TRS Type Microstructure ISO Grade Application Characteristic (GPa) (GPa) BN1000 High speed Continuous cutting Best wear resistance grade and suitable for high speed continuous cutting 27 ~ 31 0,90 ~ 1,00 Micro-grain CBN with Ceramic binder improves BN2000 Continuous and 31 ~ 34 1,05 ~ 1,15 Uncoated CBN Interrupted cutting fracture toughness and wear resistance High efficiency cutting Binder with high heat resistance improves tool BNX20 31 ~ 33 0,95 ~ 1,10 H (Continuous~Interrupted) life during high speed machining High speed Superior fracture toughness in high speed cutting and BNX25 Interrupted cutting suitable for high speed interrupted hard turning 29 ~ 31 1,00 ~ 1,10 Interrupted cutting Micro-grain CBN with higher fracture toughness BN350 (Heavy) that improves cutting edge strength 33 ~ 35 1,20 ~ 1,30 High precision New generation TiCN layer improves notch BNC2010 continuous cutting wear resistance and provides an excellent 30 ~ 32 1,10 ~ 1,20 surface finish.
