Uncoated SUMIBORON H Hardened Steel BN1000 / BN2000 Uncoated CBN grades for hardened steel machining - General Features A new uncoated type of SUMIBORON that has a newly developed high-purity ceramic binder. Both fracture and wear resistance are combined to achieve a stable tool life in a wide variety of hardened steel machining. Available in single corner and multi-corner type inserts. - Characteristics l BN1000 - Superior high-speed machining grade with the highest wear resistance of anyuncoated SUMIBORON. Sharpness Comparison Delivers excellent tool life in continuous cutting to light-interrupted cutting.- Improved fracture resistance while also emphasizing wear resistance. BN2000 ConventionalGrade Improved hardness and heat resistance from the high-purity TiCN ceramic binder. l BN2000 - General purpose grade suitable for typical hardened steel machining applications. Provides stable tool life in everything from continuous cutting to light-to-medium interrupted cutting. - High degrees of both fracture resistance and wear resistance. Significant improvements in the performance of both by employing a high-purity Compared to conventional grades, ceramic binder. small cutting edge roundness - Stable surface roughness by increasing sharpness (Figure on right). - Newly Developed High-Purity Ceramic Binder l Conventional Grade l BN1000 / BN2000 Ceramic Binder Cracks High-purity Ceramic Binder Impurities The impurities contained in the ceramic binder for conventional With the newly developed high-purity ceramic grades cause a weakening in the sintered body and binder, the BN1000 / BN2000 achieve toughness a decrease in heat resistance, which becomes the cause of cracks and improved heat resistance by decreasing (chipping) and wear. impurities to an extreme! - Recommended Application Range - Cutting Conditions l Continuous Cutting l Interrupted Cutting l BN1000 vc (m/min) f d oc 100 150 200 250 300 (mm/rev) (mm) l l l l l 120 0,03 - 0,15 0,03 - 0,2 l BN2000 vc (m/min) f d oc Interruption 50 100 150 200 250 (mm/rev) (mm)lllll Strength 80 120 light medium heavy 0,03 - 0,2 0,03 - 0,3 Depth of cut Frequency (mm) ofFeed rateInterruption(mm/rev) k Coolant ...
