automatic clamping tool holder / turning

The ROTA NCS power chuck from SCHUNK works with the active pull-down of the jaws. This hermetically sealed power chuck is ideal for applications that deal with internal and external clamping. The pendulum mechanism is incorporated at the 6-jaw chuck, and the size of the chuck must be chosen in accordance with the size of the workpiece. This ensures that the workpiece is centered amid the 6-contact points which are adjustable in couples, and that pre-machined works are centered without damage. 250 to 500 millimeter jaw versions are available, with the base jaws being SRK tongue and groove and the top jaws being of the SRK type.
