2 Grooving Tools for Small Parts Machining High Precision With Edge Width Tolerance of ±0.02mm High Efficiency Coating Technology for Long Tool Life 1 Stable Chip Control with GL Chipbreaker GL Chipbreaker for stable chip control in both grooving and traversing applications (Traversing is not recommended for GL) Twin Dots Stable Chip Control Comparison of Chip Control (In-house Evaluation) GL Chipbreaker Grooving f = 0.05 mm/rev d = 1.5 mm Traversing f = 0.04 mm/rev ap = 0.2 mm Front Edge Dots Chips are short, curled and break evenly in low feed maching operations. Prevents chip crunching. Cutting Conditions: Vc = 80 m/min, Insert width 1 mm Workpiece: SUS304 Case Studies Nozzle Parts Stainless Steel 1.5 GL Chipbreaker P1535 Vc = 45 m/min f = 0.05 mm/rev Groove depth 0.6 mm, Wet K1212JX-16F GL P ø8.0 s chips became entangled with workpiece due to unstable chip control. GL Chipbreaker maintained stable chip control without entanglement. (User evaluation) 1
