Jaeger SK-Spindles with Pneumatic Taper Tool Change

SK-Spindles Pneumatic Taper Changes

High-frequency machine spindles for high-speed milling, grinding, drilling and engraving. The insertion of the SK-Spindle into a machine tool is made by a taper adapter. The tool used in each case is changed automatically by a built-in pneumatic cylinder into the SK-Spindle. Tools are clamped through the use of WK-tapers, WK-shrinking tapers or HSK-tapers.

Jäger High Performance Spindles utilize hybrid ceramic ball bearings. These bearings have standard steel bearing races and are matched with silicon nitride balls. Advantages of hybrid bearings compared with normal spindle bearings are improvement of:

  • Reduced wear
  • Rigidity
  • Friction
  • Axial shaft movement
  • Reliability of operation
  • Vibrations
  • Fatigue life
  • Accuracy
