SUMIBORON vC (m/min)SpeedCuttingInterruption Strength Increased Wear/Reduced Sharpness Increased Wear/Reduced Sharpness SUMIBORON for Hardened Steel Machining BN1000 / BN2000 Hardened Steel BN2000 ■ General Features Uncoated SUMIBORON grades that have a newly developed high-purity ceramic binder applied to them. Both fracture and wear resistance are combined to achieve a stable tool life in a wide variety of hardened L steel machining.We offer a wide selection of tools starting with single- cornered types. BN1000 ■ Features ● BN1000 · A SUMIBORON grade for high-speed machining with the best wear resistance, Sharpness Comparison providing superior tool life in continuous cutting to light interrupted cutting. · Improved fracture resistance while also emphasizing wear resistance Improved hardness and thermal resistance from the high-purity TiCN ceramic binder. ● 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. Small cutting edge roundness compared to conventional grades · Has a high degree of both fracture and wear resistance Significant improvements in the performance of both by employing a high-purity ceramic binder. BN2000 Conventional Grade · Stable surface roughness achieved by increasing edge sharpness (right figure) ■ Newly Developed High-Purity Ceramic Binder Conventional Grade BN1000 / BN2000 CeramicCBerinadmeirc Binder CracksCracks High-puHriigtyh-cpeurarimtyicebrianmdeicr binder CBN CBN ImpuritieIms purities CBN CBN With a newWliythdaevneelowplyeddehvigehlo-peudrithyigche-rapmuriictybcinedraemr,ic binder, The impuritTiehseciomnptauirniteiedsincotnhteacineerdaminicthbeincdeerramfoirccboinvdeenrtfiornaclognrvaednetisodnaelcgreradsesthdeecrease thBeN1000 / BBNN21000000a/cBhiNev2e00to0uagchhnievses taonudgihmnpesrosvaenddthimerpmroavl ed thermal sintered bosdiyntsetrreedngbtohdaynsdtrtehnegrmthaal nredstishtearnmcael,rlesaidsitnagnctoe,cleraacdkinsg(btroecarkaacgkes) (abnrdeawkeaagre.) and wreeasri.stance breysdisetacnrecaesbinygdimecprueraistiiensgtiomapnureitxietrsemtoea. n extreme. ■ Application Range ■ Recommended Cutting Conditions 300 ● BN1000 ● BN2000 BN1000 Cutting Speed vc (m/min) Cutting Speed vc (m/min)501001201502002503005080 100 120150200250300 200 BN2000 BNX25BNX20 Feed Rate f Depth of Cut ap Feed Rate f Depth of Cut ap(mm/rev)(mm)(mm/rev)(mm) 100 BN350 0.03 to 0.15 0.03 to 0.2 0.03 to 0.2 0.03 to 0.3 Cutting Oil: Continuous Cutting Dry, Wet Interrupted Cutting Dry Continuous Light Interrupted Medium Interrupted Heavy Interrupted Small Impact Force on Cutting Edge Large L16
