HSKISOfor machining

The steep taper is the original tool interface and continues to see frequent use in the machine tool industry. Steep taper technology has proven itself for decades and, in spite of the increasingly widespread use of HSK interfaces, remains a practical solution for standard machine tools. Universal spindle contour Thanks to the spindle inside contour developed by OTT-JAKOB, various standards of tool can be used in the same spindle. The universal spindle contour is compatible with all conventional tool standards. Force intensifying mechanism OTT-JAKOB steep taper clamping systems feature a force intensifying mechanism which increases the force of the spring. The protected, maintenance-free position of the force intensifying mechanism at the back of the spindle shaft ensures reliable functionality over the entire life span of the clamping system. Power drawbars have the following advantages over spring drawbars: High pull-in forces and compact dimensions Lower release forces, which results in less spindle bearing load and the opportunity to use smaller unclamping units Easier to balance due to smaller masses Self-locking effectively prevents frictional corrosion and vibration damage to the spindle taper
