SUMIBORON H Hardened Steel Guidance for SUMIBORON Grades HARDENED STEEL MACHINING (2) ■ Applications Coated SUMIBORON: 1st recommendation for hardened steel machining, best performance in high speed and efficiency machining. Uncoated SUMIBORON: Optimal for machining small items with a limited cutting speed and hardened steel. Series Applications 300 ・First recommendation for hardened steel machining Cutting Speed vC(m/min) Coated ・Machining requiring high speed and accuracy 200 SUMIBORON ・Machining requiring high efficiency, such as Coated SUMIBORON carburized layer removal 100 ・Machining where the cutting speed cannot be increased, such as small part machining (80) 50 Uncoated SUMIBORON Uncoated ・Machining materials that contain a large amount of hard particles, such as die parts SUMIBORON ・Machining with low-rigidity tooling Frequency of Interruption Continuous Light Medium Heavy Work Induction Hardened Steel Bearing Steel Die Steel HSS Material Carburized Steel Machine Rigidity High Low ■ Application Range ● Induction Hardened Steel（S45C / S55C etc.）, Carburized steel ● Induction Hardened Steel（S45C / S55C etc.）, Carburized steel Coated SUMIBORON Uncoated SUMIBORON 300 BNC100 300 Cutting Speed vC (m/min) Cutting Speed vC (m/min) BN1000 BNC160 BNC2010 200 BNC200 200 BNC2020 BN2000 BNX25 BNX20 120 100 100 BN350 BNC300 Interruption Interruption Continuous Light Interrupted Medium Interrupted Heavy Interrupted Continuous Light Interrupted Medium Interrupted Heavy Interrupted Small Impact Force on Cutting Edge Strong Small Impact Force on Cutting Edge Strong ● Die Steel（SKD11 / SKD61 etc.） , HSS ■ Recommended Cutting Conditions Uncoated SUMIBORON Grade 50 Cutting Speed vc(m/min) 100(120) 150 (170) 200 (220) 250 300 f (mm/rev) ap (mm) L SUMIBORON 150 BNC2010 0.03 to 0.25 0.03 to 0.35 Cutting Speed vC (m/min) BNC2020 0.03 to 0.40 0.03 to 0.50 BN1000 BNC300 0.03 to 0.20 0.03 to 0.30 Coated 100 BN2000 BNC100 0.03 to 0.20 0.03 to 0.30 BN350 BNC160 0.03 to 0.20 0.03 to 0.35 50 BNC200 0.05 to 0.35 0.05 to 0.50 HSS Machining BN7000 BN1000 0.03 to 0.15 0.03 to 0.20 BN2000 0.03 to 0.20 0.03 to 0.30 Interruption Uncoated BN350 0.03 to 0.20 0.03 to 0.30 Continuous Light Interrupted Heavy Interrupted BNX10 0.03 to 0.15 0.03 to 0.20 Small Impact Force on Cutting Edge Strong BNX20 0.03 to 0.30 0.03 to 0.50 BNX25 0.03 to 0.30 0.03 to 0.50 L5
