Z-Spindles with Pneumatic Direct Tool Change
pneumatic direct changes are high-frequency machine spindles for high-speed milling, grinding, drilling and engraving. The tool used in each case is changed automatically by a built-in pneumatic cylinder into the Z-Spindle. Tools are clamped through the use of traction collets.
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
