2 Stable chip control with GL chipbreaker GL chipbreaker control chips stable at both grooving and traversing (Traversing is not recommended for GBF32R075-005GL) Twin dots Stable chip control Comparison of chip control (Internal evaluation) GL chipbreaker Competitor A Grooving d = 1.5 mm f = 0.05 mm/rev Front edge dots Chips are curled and break in short at low feed machining Prevents chip clogging Traversing ap = 0.2 mm f = 0.04 mm/rev Cutting conditions: Vc = 80 m/min, edge width 1 mm Workpiece: SUS304 Case studies Nozzle parts stainless steel 1.5 Vc = 45 m/min f = 0.05 mm/rev Groove depth 0.6 mm, wet KGBFR1212JX-16F GBF32R100-005GL PR1535 0.6 ø8.0 GL chipbreaker PR1535 Competitor A Competitor A entangled chips with workpiece due to unstable chip control. GL chipbreaker controlled chips stable without chips entangled.
