Special collet chucks for draw-back collets power operated collet chucks, stationary end stop
We manufacture special collet chucks for drawback collets with fixed end stop in different designs and with different clamping areas.
The collet chuck consists of a simple one-section chuck body, simultaneously serving as a collet sleeve. During clamping, the draw-back collet is drawn into the chuck body, and this creates a slight axial movement at the workpiece in the direction of the spindle nose. This pull-down effect causes the workpiece to be pulled against the flat surface of the fixed end stop. During unclamping the clamping cylinder pushes the draw-back collet out of the fixture.
When ordering, please specify whether short workpieces are to be fed in from the front, so that the collet can be expanded, especially where automatic loading is involved. The collet chuck is operated either via a hydraulic or pneumatic cylinder.
We manufacture these collet chucks according to customer drawings or our own designs, within ultra-short deadlines.
