Indexing chuck

Highly accurate and extremely fast swivelling

Stiefelmayer indexing chucks are designed to reduce machining times. The actuation with atandem cylinder enables an extremely fast swivelling process directly into all positions. Thanks to the precise alignment of the pins to each other, the chuck has such a high accuracy that it is also suitable for grinding operations.
