Special collet chucks for draw-back collets rotating, pressure-spring clamping

Description:
We produce rotating clamping fixtures for drawback collets with pressure-spring clamping. The axially fixed collet is clamped by the clamping sleeve, which is pressed forwards by the integrated pressure springs. The collet is unclamped by means of compressed air, which pushes the clamping sleeve backwards and thus opens the clamp. The compressed air is fed in via a stationary distributor ring.

The clamping fixture may only be used if the spindle is stationary, to avoid damage to the distributor ring. The collet is exchanged in unclamped condition. Depending on the application, the draw-back collet can be secured in the housing against distortion. Only very low amounts of clamping force are achieved with these highly compact collet chucks with pressure-spring clamping. They are therefore unsuitable when large amounts of force are applied to the workpieces requiring clamping. These devices are frequently used in the laser-marking or laser-welding machine sectors and are also used as test spindles.

These collet chucks are produced to ultra-short deadlines according to customer drawings or our own designs.
