Turning Chip Breakers New Chip Breakers MP Chip Breaker For medium cutting Chip breaker for forged steel of automobile parts and all other steels. Quad dots improve productivity through efficient chip control at high feed. Angle land minimizes cutting force. Features of MP Chip Breaker Front two step dot - Higher stability of chip curls at high feed - Excellent chip control when copying - Lower cutting force at high depth of cut Variable land - Less crater wear - Prevents chipping on minor cutting edge - Higher toughness at high depth of cut and interrupted cutting Flat zone 0. _5 '7 SECTION A-A Larger chip pocket for better chip evacuation at high feed Reduced cutting force with larger contact surface of chips ( Application Range (Medium to finish cutting) 5.0 4.0 3.0 2.0 1.0 0.1 0.2 0.3 Wear resistance test Workpiece i Cutting conditions i Tool SCM440 (Alloy steel) 0100 Outer diameter machining vc(m/min) = 280 ap(mm) = 1.5 fn(mm/rev) = 0.25 / 0.40 wet CNMG120408-MP Medium feed (0.25mm/rev) 0.4 0.5 feed, fn(mm/rev) Cutting time (min) Competitor A Competitor B CNMG120408-MP Competitor A Competitor B (NC3225) (P25) (P25) MP High feed (0.40mm/rev)
