Spindle units for draw-back collets – plate spring clamping

These spindle units work via plate spring clamping. The draw-back collet is pulled into the fixture by plate springs and thereby closed. Unclamping takes place mechanically by using a single-acting lever to relieve pressure on the collet; the lever can also be designed as a double-acting lever.

The spindle is located on two grooved ball bearings and one spindle bearing. The spindle is driven via a synchronizing disk with a toothed belt. The collet can be clamped and unclamped while the spindle is in operation. The collet is secured against distortion inside its housing.

The motor is supplied by Nann or mounted by the customer.
