SUMIBORON TypeUncoated CBNCoated CBNTypeUncoated CBN 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 Microstructure ISO Grade Application Characteristic Hardness(Hv) TRS(GPa)(GPa) BN1000 High speedContinuous cutting Best wear resistance grade and suitable forhigh speed continuous cutting27 ~ 310,90 ~ 1,00 BN2000 Continuous andInterrupted cutting Micro-grain CBN with Ceramic binder improvesfracture toughness and wear resistance31 ~ 341,05 ~ 1,15 H BNX20 High efficiency cutting Binder with high heat resistance improves tool(Continuous~Interrupted)life during high speed machining31 ~ 330,95 ~ 1,10 BNX25 High speedInterrupted cutting Superior fracture toughness in high speed cutting andsuitable for high speed interrupted hard turning29 ~ 311,00 ~ 1,10 BN350 Interrupted cutting(Heavy) Micro-grain CBN with higher fracture toughnessthat improves cutting edge strength33 ~ 351,20 ~ 1,30 BNC2010 High precisioncontinuous cutting New generation TiCN layer improves notchwear resistance and provides an excellent30 ~ 321,10 ~ 1,20 surface finish.
