Grooving Cutting force［N］ Residual rate (%) Cutting force［N］Cutting force［N］ 6.0 φ33 Internal grooving EZG type KGDI: Stable machining with excellent chip control and smooth chip evacuation 1. Excellent chip control with GMI chipbreaker for internal grooving Evenly breaks chips in various cutting conditions with newly designed chipbreaker geometry. Good chip control even in finishing applications with small depths of cut. Rear ramp Center geometry squeezes chips and Comparison of chip control (Internal evaluation)prevents chip clogging during high supports chip deformation. feed machining. GMI Chipbreaker Competitor A Conventional product F Smooth chip control with stable chip shape compared with Competitor A and Conventional F. Prevents frequent machine stops caused by G tangled chips. Corner design stabilizes chip shape Front design stabilizes during finishing and improves chip chip shape during low Cutting conditions : Vc = 100 m/min, f = 0.07 mm/rev, toolholder: KGDIR3225B-3 breaking performance. feed machining.
