Abstract:
Machine tool comprisinga machine frame,at least one workpiece spindle,a workpiece being clampable in said spindle and drivable for rotation about a workpiece spindle axis, said workpiece held in the workpiece spindle and being rotatable about the workpiece spindle axis into defined rotary positions by means of a numerically controlled C-axis,a support, the workpiece spindle being arranged on said support and the workpiece spindle being movable with said support relative to the machine frame and transversely to the workpiece spindle axis into at least two spindle stations stationarily arranged with respect to the machine frame,at least one tool carrier associated with a selected one of the spindle stations, comprising a transverse-slide carrier mounted on the machine frame and having a transverse slide for a tool, said transverse slide being movable in a linear direction and in a controlled manner with respect to said transverse slide carrier so as to move the tool in an X direction relative to the workpiece spindle located in the selected spindle station, said transverse-slide carrier being pivotable in relation to the machine frame about a pivot axis extending parallel to the workpiece spindle axis of the workpiece spindle located in the selected spindle station by means of a pivot drive in a numerically controlled manner,a tool spindle provided on the transverse slide for receiving a tool drivable for rotation about a tool spindle axis, said tool spindle axis forming with the X direction an angle of less than 45.degree..
