1 Easy insert replacement Reduce down time with fast insert replacement Turn wrench slightly to release insert No hammer or screw required Self-clamping 2 Firm insert clamp ensures added safety and security The firmly secured insert uses three contact surfaces to eliminate sliding or chattering 1. Top clamp Holds the insert in place 2. Back stop Prevents insert retraction and makes mounting inserts easier Insert deviation comparison (internal evaluation) 200 KPK Competitor A 160 Insert o set (μm) Separate contact surfaces Front Contact : Improves stability Back Contact : Prevents insert slipping 3. V-Shaped insert seat Optimized insert seating prevents insert movement 120 80 40 0 0 20 40 60 Load (N) Measured tool: KPKB32-3 PKM30N-025PM Load 80 100 Cutting performance comparison (Internal evaluation) KPK Competitor A Competitor B Chip clogging Chip entanglement Good Cutting noise and surface finish: Good stable machining Damaged Chip clogging Scratches on the finished surface Chattering Chip entanglement Chattering when entering the workpiece Cutting conditions : n = 320 min -1 (constant) , Vc = ~ 100 m/min , f = 0.12 mm/rev , Wet (External coolant) Workpiece: 34CrMo4 (ø 100) Cutting width: 3 mm (PM chipbreaker) 2
