Abstract

A machine tool for machining planar workpieces includes an upper tool, a lower tool, a machine frame, and a controller. The upper tool is movable with a stroke movement along a stroke axis by a stroke drive device in a direction towards a workpiece and in the opposite direction and positionable with an upper traversing movement along an upper positioning axis by a motor drive assembly. The lower tool is aligned with the upper tool and is positionable with a lower traversing movement along a lower positioning axis by a motor drive assembly. The upper and lower tools are movable in a frame interior of the machine frame. The motor drive assemblies can be controlled by the controller. The upper and lower traversing movements can be controllable independently of each other. The upper tool can be controlled with the upper traversing movement and the stroke movement in a superposed manner.
