Stiefelmayer Clamping Technology

Wedge bar chuck

Place long workpieces deep down and clamp them securely

The wedge bars inserted in the chuck body place the jaw guide in the area of the clamping point. This means that the workpiece can be clamped securely and no higher top jaws are required.

Our wedge bar chucks can also be equipped with a large opening. In the case of complete hollow clamping, this also allows the workpieces to be loaded via the rear of the chuck.
