Application:

This hydraulically-operated concentric clamping element can be equipped with especially low clamping jaws to receive workpieces with interior centrings of low depth. Suitable workpieces can directly rest on the clamping jaws so that additional support points are not required. With a combination of 2 and 3-point elements, workpieces with 2 centring holes can be exactly positioned.

Description:

The 2 or 3 base jaws are coupled to a coneshaped contact bolt in the centre of the housing, that is driven by a double acting hydraulic piston. To obtain the required synchronization accuracy all parts are manufactured with high precision. The nitrated base jaws have 3 fixing threads. Depending on the desired centring diameter, the accordingly adjusted clamping jaws can always by fixed with at least 2 screws. The exact position of the clamping jaws is secured with 2 drill bushings.
