Abstract

The device has an output strand (6) comprising a boring sleeve (10) and a forge. The boring sleeve is radially supported in a rotatable manner around a longitudinal axis in relation to a machine housing (33). The boring sleeve is axially supported via a roller bearing arrangement for receiving of axial forces that are induced at a tool. The boring sleeve is held in the machine housing at both axial sides by axial acting soft and elastic deformable damping elements (34, 36), which are designed in a circular disk type. The damping elements are made of plastic material/polyurethane foam.
