Ify^IMUD^ TAC boring bars chipbreaker line Sharpness of positive inserts with twice the number of cutting edges

Remarkable edge sharpness reduces cutting forces while the double sided insert increases the number of cutting edges I | Uniquely designed double sided insert Minimum bore diameter: o12 mm —► Economic advantages with twice the number of cutting edges Advanced edge shape reduces the cutting forces —► Similar design to positive type inserts to prevent chattering G-Class Inserts create precision machining One insert type for toolholder shank diameter range from One insert type for the minimum bore range from 12 mm diameter upwards, Ideal grade series for various applications —► AH725 for...

High performance boring bars with new optimum design Excellent chip evacuation and high rigidity (Same structure as StreamJetBar series) Conventional positive type insert Similar to positive type Rake angle Optimum design for smooth chip evacuation and high rigidity Optimal space to evacuate chips Oil hole directs coolant to the cutting edge Special structure for rigid clamping Screw clamping with high rigidity Dove-tail structure (wedge shape) creates high clamping force Cutting performance Anti-vibration design Same strength performance as positive type inserts Steel shank Cutting speed...

Workpiece type Machine parts Machine parts Insert Grade Tool life is Doubled ! SS chipbreaker creates same level of surface nish and tool life per insert edge as the competitor. Double sided insert can machine twice the number of work pieces with one insert compared to competitor’s alternative. Number of pieces (pcs / corner) Feed : f (mm/rev) Depth of cut : ap (mm) Machining Coolant Cutting speed : Vc (m/min) Number of pieces (pcs / insert) Cutting conditions Work material Tool life improved 50% ! When using competitor’s tool, the machining is frequently stopped due to vibration or chip...
