Turning Chip Breakers Features of Chip Breaker Single-sided VL Chip Breaker For finishing The sharp flank surface and the chip breaker design significantly improve chip control when machining tough materials such as low carbon steel, pipe steel, and iron plates Sharp cutting edges reduce cutting resistance and provide excellent chip control at low depth of cuts, leading to stable machining on automated production lines O Features of VL chip breaker Sharp cutting edges - High rake cutting edges provide improved surface finishes - Low cutting resistance reduces cutting heat 2-step rear rake angle - Stable chip control regardless of varying feed rates - Excellent machinability even when machining mild workpieces Chip control test Workpiece SCM440(Alloy steel), 050, Internal diameter turning Cutting condition vc = 250 m/min, ap = 0.3 1.5 mm, fn = 0.05 0.25 mm/rev Tools CCMT09T304-VL sa 1.5 1.0 0.5 0.3 0.05 0.10 0.15 0.20 0.25 feed, fn (mm/rev) Single-sided MP Chip Breaker For medium to finishing For continuous cutting of forged steel at high feed Turning insert for internal machining of automobile components O Features of MP chip breaker Three-dimensional 2 step chip breaker - Stable chip control in unstable internal machining - Prevents chip blocking at infernal diameter at varying depth of cut and feed. Stronger cutting edge and wide chip pocket - Increased chipping resistance in unstable internal machining O Chip control test Workpiece SCM440 Cutting condition Tools vc = 200 m/min, ap = 0.5 2.5 mm, fn = 0.05 0.25 mm/rev CCMT09T304-MP Turning 2.5 1.5 1.0 0.5 ;r.
