Abstract
A machining center that includes a swivel bridge supported by a bearing wall and pivotable about a horizontal axis, at least one drive sprocket attached to a disc-type connector of the swivel bridge, and at least one drive system attached adjacent the bearing wall and operatively connected to the drive sprocket of the swivel bridge. The machining center is characterized by clamping of the swivel bridge being performed by a friction-locked clamping system which is arranged rotationally fixed about a bearing pin of the swivel bridge in a circular ring shape and which is operatively connected to the disc-type connector. A clamping force of the friction-locked clamping system is generated by an energy storage.
