The principle of the clamping bushing moving towards the back, the so-called pull-back effect, can provide substantial stability to the work piece. Even if the relationship of the clamping diameter and clamping length is obviously disproportionate to the size and the length of the work piece, unbelievable clamping results can be achieved.

Our experts are happy to advise you and show you similar solutions that we have already implemented. And you will be surprised to see just how many there are.

Mandrel type 212
This version allows an optimal clamping length for blind bores. The minimum clamping diameter is 20 mm. With this type of mandrel, the segmented clamping bushing moves axially on the fixed mandrel taper. That makes the use of an internal front end-stop possible.

Mandrel type 213
In principle, it is similar to the MANDO. The opening of the bushing is achieved through the lip on the clamping bolt. Suited for smaller clamping diameters of 18 to 40 mm. The clamping bushings are delivered together with the clamping bolt. This version is not suited for short clamping length.
