Polygonal Toolholders

SCHUNK, the competence leader for clamping technology and gripping systems, offers Polygonal Toolholders for mMicro machining with balancing grade extremes. Polygonal toolholders of the TRIBOS-Mini and TRIBOS RM series are available with the interfaces HSK-E 25, HSK-E 32,and HSK-F 32 starting from clamping diameter 0.5 mm, on option also ultra-fine balanced at a balancing grade of G 0.3 at 60,000 rpm. Therefore demanding requirements in terms of dimensional accuracy and surface quality in the micro-mould making can now be met in the optical industry, the medical technology, and the watch and jewellery industry can be met. Compared to conventional balanced toolholders for micro machining, their tool life is longer. Since expensive cutting edges are used for micro machining, an excellent balance grade pays off after a very short period of time. Even the standard mountings convince with a run-out and repeat accuracy of less than 0.003 mm at an unclamping length of 2.5 x D and a balancing grade of G 2.5 at 25,000 rpm. They are suitable for every tool shank in h6 quality, and depending on the type, tested up to 205,000 rpm. Since the mountings have no movable parts, they are mechanically insensitive, and ensure almost maintenance- and wear-free clamping. Even after several thousand clamping rounds there are no signs of material fatigue. Additionally, tool change of TRIBOS is process-reliably done via a hydraulic clamping device within a few seconds.
