Special collet chucks for internal clamping, screwspring clamping, single-taper clamping sleeves
We produce rotating clamping fixtures for internal clamping with helical spring clamping for single-taper clamping sleeves.
In this device the mandrel remains axially fixed. The clamping sleeve is equipped with a collar. A retaining ring holds the clamping sleeve firmly to this collar. A cross-pin leads through the retaining ring and the compression mandrel, via which the clamping sleeve is drawn backwards over the mandrel. This is achieved by the helical springs integrated into the collet chuck. Unclamping is done via compressed air. Impingement on the collet chuck by means of compressed air moves the compression mandrel forward, the clamping sleeve detaches itself from the mandrel and the workpiece can be removed. The compressed air is fed in via a stationary distributor ring. This distributor ring lies on the chuck body by means of a plastic ring. Exchange of the clamping sleeve must always be done in clamped condition.
The collet chuck is tailored to your individual requirements. Clamping range, rotational speed etc. will be manufactured according to customers’ preferences.
