Abstract
In order to improve a multiple-spindle turning machine comprising a machine frame, a spindle drum arranged to rotate relative to the machine frame around a drum axis having a number of work piece spindles movable in the direction of rotation, said work piece spindles being respectively provided with a work piece receiving means for a work piece, and a number of stations, comprising at least one machining station, arranged consecutively on the machine frame in the direction of rotation of the work pieces corresponding to the number of work piece spindles, in such a way that the number of tools which may be used can be increased at low expense, it is proposed that for machining the work pieces, the at least one machining station has a first and a second spindle position, which are arranged at an angular distance from one another relative to the drum axis; that the spindle drum is rotatable in such a manner that a work piece spindle with a work piece may be positioned in each of the spindle positions; and that each spindle position is provided with its own machining tool.
