TRIBOS polygonal toolholder

Specials Precision toolholders

Nov 2, 2015

SCHUNK has developed TRIBOS polygonal toolholder technology in order to achieve precision in the sub-micron area during ultra-precision machining. The 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 jewelry 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. Additionally, tool change of TRIBOS is process-reliably done via a hydraulic clamping device within a few seconds.
