ABSTRACT:
A method is disclosed for operating a machine tool which comprises a spindle rotatable about a spindle axis; a spindle gripper, carried by the spindle, for gripping workpieces; and a cradle apparatus that can be pivoted back and forth about a pivot axis of the cradle apparatus extending approximately perpendicular to the spindle axis. In the method, the cradle apparatus with a clamped workpiece is set up in a first position, whereupon the clamped workpiece is removed from the cradle apparatus and held with the spindle gripper. The empty cradle apparatus is then pivoted into a second position, and/or the spindle gripper holding the workpiece is pivoted about the spindle axis. Lastly, the workpiece held by the spindle gripper is inserted back into the cradle apparatus, and the latter is pivoted into a further position for further machining of the workpiece that is once again clamped in.
