ABSTRACT:
In order to improve a multiple-spindle turning machine, comprising a machine frame, a cylinder rotatable around an essentially horizontal rotational axis relative to the machine frame, work piece spindles arranged on the cylinder in respective individual positions with spindle axes, which are aligned essentially parallel to the rotational axis and which during the machining of a work piece are movable relative to the cylinder by means of linear drives in the direction of their spindle axis and independently of one another, and tools arranged on tool supports for machining the work pieces held in the work piece spindles, in such a way as to allow the respective work piece spindle to be positioned as precisely as possible in the direction of its spindle axis, it is proposed that each of the work piece spindles is allocated its own linear drive disposed on the cylinder to move it in the direction of the spindle axis, and that the work piece spindle is constantly coupled to the linear drive.
