211 Kitty Hawk Dr.
Morrisville, NC, 27560
Press release date: April 9, 2014
The TRIBOS-Mini HSK-E 20 polygonal toolholder is the first standardized precision toolholder for micro machining with the HSK-E 20 spindle interface from SCHUNK. In comparison to conventional steep taper interfaces, the HSK-E 20 interface ensures excellent change and positioning accuracy, as well as high process reliability. The narrow tolerances of the tapered seat ensure maximum precision at high rotation speeds.
With a repeat accuracy of ≤ 0.003 mm at 2.5 x D and a balancing grade of G 2.5 at 25,000 rpm, the TRIBOS-Mini HSK-E 20 meets the highest standards. It is suitable for all tool shanks in h6 quality, transmits torque up to 4.5 Nm (at ø 6mm) and is rated up to 85,000 RPM.
Both the precision on the workpiece, and the service life of the tools benefit from the excellent concentricity properties. Reliable tool changes can be done in seconds with the help of a hydraulic clamping device. The HSK-E 20 is available for ø 1.0 mm, 1.5 mm, 2.0 mm, 3.0 mm, 4.0 mm, 6.0 mm and 1/8". The L1 dimension is 35 mm. In addition, smaller shank diameters down to 0.3 mm, and other special designs are possible.
