A machine tool for selectively machining workpieces with cutting tools and a laser beam having a machining unit including a motor-driven work spindle for machining workpieces with cutting tools, a laser beam source including a beam guiding arrangement for machining workpieces with a laser beam, and a work table movable by means of a motor for clamping at least one workpiece thereto. To enable machining by means of cutting tools as well as machining by means of a laser beam with a construction of simple design without complicated exchange operations, the beam guiding arrangement is arranged on the machining unit so that it is displaced with respect to the work spindle.
