Special collet chucks for internal clamping power-operated with clamping sleeve
We manufacture special collet chucks for clamping sleeves in different designs with differing chucking ranges. The collet chuck consists of a simple chuck body, which simultaneously serves as a clamping taper. The double taper expansion sleeve and the compression mandrel are drawn onto the clamping taper, and the workpiece is clamped.
For unclamping, the compression mandrel is pushed forward, the clamping sleeve detaches itself from the clamping taper, and the workpiece can be removed. Depending on the type of application this type of mandrel can be equipped with a fixed end stop, so that the workpiece for clamping is always clamped in the same position axially, since a pull-down effect is created during the clamping process.
If you want to clamp very long workpieces, these mandrels are designed for two clamping sleeves lying behind each other. Fixture of the collet chuck is carried out according to customers’ wishes. In most cases the chuck body is designed with a cylindrical flange, but a short taper fixture is also possible anytime. As a matter of course an intermediate flange can also be attached.
