Special clamping fixture for deadlength collets, hydraulic

We manufacture special clamping fixtures in all kinds of different designs using standard clamping devices. The clamping fixture consists of a taper shaft with cylindrical flange, inside the spindle of an NC indexing unit. A base-plate is attached to this cylindrical flange on which a standard clamping device of type HZ 25 is mounted for clamping the workpiece. Since a very long workpiece is to be clamped, it has to be centred on the side opposite the clamping fixture and clamped as well. A hydraulic swivel clamp is used for this purpose.

To feed in hydraulic oil, a rotational feed is attached to the end of the taper shaft, which is also manufactured by Nann. We manufacture these collet chucks according to customer drawings or Nann designs ia a very short time.
