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