Special collet chucks for internal clamping for manual operation with direct expanding collet
We manufacture special collet chucks for direct expanding collets in various designs with different chucking ranges.
The collet chuck consists of a basic fixture, onto which the mandrel is screwed. The expansion sleeve is drawn backwards for clamping by means of the intermediate section and the crossbar. For unclamping, the expanding collet is pressed forward again through the intermediate section and the crossbar, the expanding collet closes, and the workpiece can be removed. Clamping activation is by turning the clamping key using a hexagonal spanner on the underside of the device.
Depending on the type of application, these types of mandrels can be fitted with a fixed end stop so that the workpiece for clamping is always clamped axially in the same position – because during clamping a pull-down effect occurs that pulls the workpiece onto the flat surface of the end stop. This type of expanding mandrel is especially suitable for clamping very short workpieces.
