Schunk expands Tribos line of precision toolholders for micro machining
- Published: May 24, 2017
Schunk has expanded its micro machining precision toolholder line with the new Tribos-mini for micro applications, now available for high speed spindle interface HSK-E-20.
Compared to conventional steep-angle taper interfaces; the HSK-E 20 ensures exact contact of the toolholder, which allows outstanding change and positioning accuracy. In addition, the close tolerances of the tapered seat result in maximum precision and superior running smoothness at high speeds.
Schunk has made improvements in other interfaces as well: the Tribos-Mini and Tribos-RM series with the interfaces HSK-E 25, and HSK-E 32, starting with clamping diameters of 0.5 mm are now optionally available in fine-balanced versions with a balancing grade of G 0.3 at 60,000 rpm. Tribos can also be used for applications with very high requirements for dimensional stability and surface quality.
For multi-axis machining centese, Schunk has modified the robust Tribos-RM with an extended L1 dimension of 78 mm. The extra length can be used for many different tasks: in addition to direct clamping it is suitable for clamping of smaller shank diameters. For machining of hard-to-access areas, the toolholder can also be combined with the standardized Tribos-SVL Mini tool extension. The universal five axis expert is available for the interfaces HSK-A 32, HSK-A 40, HSK-E 32, and HSK-E 40. Its shank diameter is 12 mm for all of these interfaces.
Tribos-Mini is now standardized with diameters of 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 6 mm, and 1/8 in. Tribos-RM with diameters of 3 mm, 4 mm, 6 mm, 8 mm, 10 mm , 12 mm, and 1/8’ in. In addition to the existing interfaces HSK-A 25, -A 32, -A 40, -E 25, -E 32, and -E 40, both holders are now available for HSK-E 20 and for BT 30.
