Boring ap (mm) Introduction  AD Bars interchangeable head boring bars with anti-vibration dampener system The AD (Advanced Dampener) system enables a maximum overhang of 6 times L/D. Highly efficient machining: The anti-vibration dampener effect enables large cutting-depths and high feed rates. Applicable for a variety of machining conditions due to the interchangeable head design. Special dampener system made from heavy metal F How to exchange heads For lever lock type Interchangeable head, use 2 short bolts for upper side and 1 long bolt for lower side. HA32 SCLC&09-40 and HA32 SDUC&11-40 use HH5X20 for all 3 bolts. 1. Align hole positions 2. Tighten 3 bolts to attach the head Possible machining area: Guide-Line for overhang length of AD Bars 34CrMo4 Vc = 150 m/min 3.0 ap = 0.5~3 mm f = 0.1~0.3 mm/rev 2.0 TNMG160408 L/D = 6 1.0 0 0.1 0.2 0.3 f (mm/rev) Double clamp boring bars for negative inserts Stable machining is realized in double clamp and direction adjustment mechanism coolant hole. Improved clamping Direction adjustment Nozzle setting rigidity mechanism coolant hole Firmly clamp the insert in Discharge direction of coolant is Wrench etc. that enters two directions with one action. adjustment exible focusing on 2.5 or less holes are Along with improving the coolant to edge reliably builds up used, and adjust. accuracy of the insert Not applicable to high-pressure coolant position, long tool life can be achieved.
