ABSTRACT:
In order to improve a multiple-spindle automatic lathe comprising a working area, a spindle drum having several spindles in different spindle positions, the spindles being adapted to be brought into different spindle stations on a machine frame by rotation of the spindle drum about a spindle drum axis, a bar stock feed means associated with at least one spindle, and a stop arranged in the working area and having a stop surface for bar stock, such that the stop can be arranged so as to save more space, it is proposed that the stop be mounted for rotation concentrically with the spindle drum axis, and that the stop be fixable relative to the spindle drum during bar stock feed in an initial position in which the stop surface intersects a feed direction of the bar stock located in the spindle position associated with this initial position.
