E Technical Information for Laser Mill Features of KF / KH Chip Breaker KF Exclusive chip breaker for stable machining of carbon steel with its characteristics of high wear resistance at center part and improved blade design. KH Stronger insert with the combination of rake angle and relief angle that are ideal for machining high hardness workpiece. Type Shape comparison Standard (For general cutting) KH (For high hardness steel) KF (For carbon steel) f / r SE( I SECTION A-A Proper to general cutting Insert shape for uniform performance Center shaper proper for machining high hardness workpiece and uniformed tool life at center part Improved cutting edge design by higher rake angle(a°) Lower relief angle(B°) increases strength of cutting edges than universal inserts. Smaller chisel improves wear resistance at center for machining carbon steel. Improved cutting edge design by higher rake angle(a°) Longer tool life and better cutting performance with the use of excellent blade design Recommended Cutting Conditions Workpiece Grade Chip Recommended cutting conditions ISO Material HB(HrC) breaker vc(m/min) fz(mm/t) ap(mm) ae(mm) K Gray cast iron GC250 180(8) PC2015 130-21C 0.2 0.5 0.07D 0.07D Ductile cast iron GCD600 250(24) PC2010 KF Carbon steel S20C S50C 150 PC2005 170 250 0.2 0.5 0.07D 0.07D Alloy steel SCM21 SCM5H 270(28) 130 210 0. i 3 0.7D 0.7D KP4M 300(32) Pre NIMAX 370(40) PC2010 PC2015 PC210F KH hardened CENA1 370(40) 100 160 0. i 3 0.5D 0.5D P steel NAK80 400(43) STAVAX 510(52) High speed tool steel SKH51 SKH59 550(55) PC2005 PC2010 80 130 0. i 2 0.3D 0.3D Alloy tool steel STD61(Hot forging) 630(60) KH 70 120 0. 2 0.3D 0.3D STD11(Cold forging) Overhang vc(m/min) fz(mm/t) Under 3D 100% 100% 3D 5D 70% 70% 230
