Special collets, segmented clamping sleeves

We manufacture special expanding sleeves as segmented sleeves with hardened steel segments according to Nann designs or customer drawings. Segmented clamping sleeves are characterised by hardened low-wear steel segments which are vulcanized. They are especially made for clamping workpieces having an inner geometry accessible from outside in the form of boreholes or a prismatic holding fixture.

There is a great variety of different segmented clamping sleeves. The sleeves are activated by tension or compression, with either the expanding sleeve or the mandrel is fixed or, respectively, moves. On request we also manufacture end stops suitable for the expanding collet.

Please don’t hesitate to contact us. We will be glad to provide tailormade clamping devices for your requirements.
