Abstract
Described is a coupling, provided at the spindle head of a machine tool, for clamping an especially plate-shaped work-holding fixture, for example a pallet, in a specified, repeatable and precise position relative to a spatial reference system, wherein the spindle head exhibits a collet, which can be moved axially and radially with respect to its face. To increase the accuracy when machining a workpiece, there is a plate, which is to be connected to the face and is provided with spatial references on the front side, and which has a central passage opening to receive a tension rod, connected to the backside of the work-holding fixture, and a bolt, whose front end can be coupled with the tension rod and whose rear end can be connected to the collet.
