Spindle units for deadlength collets hydraulically operated – plate spring clamping
We manufacture spindle units for deadlength collets with different chucking ranges.
These spindle units are mostly designed for plate spring clamping. To close the pressure collet, the plate springs press on the clamping sleeve, which is pushed forward. The collet is pressed against the union nut and closed.
Unclamping takes place via a double-action piston. The return movement of the piston is operated hydraulically. The spindle is located on two spindle bearings and one grooved ball bearing. The outer rings of these bearings have play at their seats and are cushioned by O-rings. The spindles are driven via a flexible coupling. The device may only be operated in clamped condition.
The motor is supplied by Nann or mounted by the customer.
