Hollow Shank Drawbars and Grippers - OTT-JAKOB HSK
GAIN HIGHER TOOL POSITION ACCURACY WITH OTT-JAKOB HSK
- Higher position accuracy of the tool due to axial face and taper position.
- Ideal for high speed machining.
- Easy tool handling due to low weight and dimensions of the short taper.
- Heavy duty chip removal can be achieved through total stiffness of the Interface, high pull forces and the resulting transmittable torque.
Since its standardisation, HSK has become a standard interface in machine tool technology. With the congruence between the flange and taper contact surfaces, the HSK clamping system is ideal for highly precise machining results and a repeat accuracy on the micro scale. The hollow-shaft taper (HSK) has a shorter, lighter structure than the steep taper, which allows tools to be changed more quickly and higher speeds to be reached. By virtue of its high pull-in forces, excellent stiffness and optimal torque transmission, HSK is also ideal for use in heavy machining.
HSK Type K is the most cost-efficient solution in the range of OTT-JAKOB HSK-Clamping-Units. A solid basic variant, it is well suited for standard applications and a high-quality coating gives it a long life span.HSK-K Technical Manual
HSK Type B is a high-performance clamping unit, designed for frequent, quick tool changes. The restricted guidance ensures that the grippers move in parallel even in the most difficult conditions, and the reduced friction leads to a higher transmission ratio. A high-quality, DLC coating gives it the longest possible life span.HSK-B Technical Manual
HSK Type C HSK generates extremely short tool-changing times. The built-in holding function minimizes waiting time during the tool-changing process. Our high-quality, optimised DLC coating also gives it a long life span.HSK-C Technical Manual
Based on Type B, this clamping unit provides an even higher transmission ratio with an identical internal contour.
For the shortest possible spindle lengths, shorter variants of many Type B clamping units are also available.
