Indexing Chucks -
Highly Precise and Extremely Quick Swivelling

Stiefelmayer swivel chucks are designed  to reduce machining times on the workpiece: 

This is due to tandem cylinders which enable an extremely fast swiveling process, in all positions (90°, 180°, 270°).

The precise alignment of the tappets leads to such a high accuracy that the chuck is also suitable for grinding operations.

Technical features:

• extremely high swivelling speed (0.4 sec)
• equal swivelling time in all positions
• high re-run accuracy due to sturdy mechanics and hydraulic control
• mechanical check of swivelling position
• centric or one-sided clamping
