For automatic lathes Molded sharp edge chipbreaker series Large lineup to solve common chip control problems. Long tool life and stable machining with PR1535. 1 Excellent chip control in a wide range of machining applications 2 High precision with periphery grinding and sharp edge specification 3 Anti-welding properties with improved mirror surface finish Low cutting force chipbreakers SK chipbreaker: for low cutting force finishing ap: 0.5 mm to 3.0 mm The molded chipbreaker addresses both sharpness and chip control. Chip control comparison (In-house evaluation) C45 SK chipbreaker Competitor A 3.0 2.5 Unstable chip control ap (mm) 2.0 1.5 1.0 0.5 0.03 0.05 0.07 0.10 0.13 0.15 0.03 0.05 0.07 0.10 0.13 0.15 f (mm/rev) Cutting conditions: Vc = 100 m/min, wet, DCGT11T302 Stable chip evacuation due to large slits and large rake angle. Chip control is improved in small depths of cut due to chipbreaker projecting to the corner tip. The cutting force is reduced as the cutting blade is lowered towards the center of the workpiece. X5CrNi18-10 SK chipbreaker 2.5 Competitor B 2.0 Unstable chip control ap (mm) 1.5 1.0 0.5 0.03 0.05 0.07 0.10 0.13 0.03 0.05 0.07 0.10 0.13 f (mm/rev) Cutting conditions: Vc = 100 m/min, wet, DCGT11T302 CK chipbreaker: Low cutting force for general purpose ap: 1.0 to 2.5 mm Smooth chip evacuation with a large rake angle. A large rake angle reduces cutting forces and maintains stable chip evacuation. The cutting force is reduced as the cutting blade is lowered towards the center of the workpiece.
