Patent ID: 8196277

Claim:
Machine tool comprising a machine frame, a first spindle arranged on the machine frame for accommodating a workpiece, a first carrier for first machining units arranged on the machine frame, said carrier being movable relative to the machine frame in the direction of a first X axis transverse to a first spindle axis of rotation of the first spindle, wherein the first spindle and the first carrier are movable relative to one another in the direction of a Z axis parallel to the first spindle axis, a second carrier for second machining units arranged on the machine frame, said second carrier being movable relative to the machine frame at least in the direction of a second X axis transverse to the first spindle axis and, in addition, varying second machining units being movable with said second carrier into or out of a functional position associated with the workpiece in the first spindle in a further transverse direction extending transversely to the second X axis and transversely to the Z axis, the machine tool also comprising an additional carrier for additional machining units arranged on the machine frame, the second carrier bearing a second spindle, wherein as a result of movement of the second carrier, the second spindle is movable in the direction of the Z axis and the further transverse direction between a workpiece takeover position aligned with the first spindle and at least one workpiece machining position, and the additional machining units being arranged in a spatial area where machining of an exposed side of the workpiece held in the second spindle is adapted to be carried out with said second spindle located in the at least one workpiece machining position.
