Beschreibung
Zusammenfassung:	A machine tool for processing workpieces comprises a stroke drive device with a pressing tool, with a motorized drive including two motorized drive units which are controlled independently and wedge gear elements between the motorized drive and the pressing tool. The wedge gear elements comprise two drive-side wedge gear elements, each one being associated with a motorized drive unit, and two output-side wedge gear elements attached to the pressing tool, with each output-side wedge gear element opposite to an associated respective drive-side wedge gear element and forming a gear element pair. The wedge gear elements of each gear element pair are opposite each other inclined at a wedge angle with respect to a positioning axis and inclined in opposing directions with respect to the positioning axis. The motorized drive is configured to move the pressing tool along a stroke axis and position the stroke drive device along the positioning axis.
