Spindle units for draw-back collets for internal clamping pneumatically operated – plate spring clamping
We manufacture spindle units for draw-back collets in various designs and with different clamping ranges.
This spindle unit works with plate spring clamping. An expanding collet for the internal clamping of workpieces is integrated. The expanding collet is designed as a three-section draw-back collet. It is pulled into the fixture by plate springs and thereby closed. Unclamping takes place via an integrated single-acting piston. The spindle is located on three spindle bearings. Spindle drive takes place via a toothed belt. The collet itself is secured against distortion inside its housing.
The motor is supplied by Nann or mounted by the customer.
