Patent ID: 8051543

Claim:
A composite working lathe comprising: a workpiece spindle for gripping a workpiece having a rotational axis; a tool spindle on which a tool is attached in exchangeable manner, wherein the tool spindle moves along a Z axis parallel to the rotational axis of the workpiece spindle, an X axis orthogonal to the rotational axis of the workpiece spindle, and a Y axis perpendicular to a plane formed by the Z axis and the X axis, and pivots around a B axis which is a pivot axis perpendicular to the plane formed by the Z axis and the X axis; a workpiece handling device, wherein the workpiece handling device is moved along a first axis line parallel to the rotational axis of the workpiece spindle and the workpiece handling device comprises: a workpiece handling head that pivots around a second axis line perpendicular to a vertical plane, and a gripper disposed on the workpiece handling head for gripping the workpiece, wherein the vertical plane includes the rotational axis of the workpiece spindle, the second axis line is positioned below the rotational axis of the workpiece spindle, and the workpiece handling head of the workpiece handling device is positionable at a plurality of pivot positions in addition to a position for positioning the gripper on the rotation axis of the workpiece spindle.
