ABSTRACT:
In order to improve a multiple-spindle turning machine comprising a machine frame, two cylinders arranged on opposite sides of an operating area and mounted on the machine frame to be respectively rotatable around an essentially horizontal rotational axis, machining means arranged on the cylinders in respective individual positions with central axes aligned essentially parallel to the rotational axis, and tools for machining work pieces held in at least one portion of the machining means, in such a way that it may also be used as universally as possible for other work pieces, it is proposed that the cylinders are rotatable around their rotational axis independently of one another relative to the machine frame.
