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.

Abstract: In order to improve a machine tool with a motor spindle, including a main motor integrated into a work spindle coaxially with the spindle axis, the main motor, for its part, comprising a rotor and a stator, and with a cooling device for supplying cooling surfaces of the main motor with a gaseous coolant, so that simple and effective cooling of the main motors of the motor spindles is possible, it is proposed that the stator be comprised of stator plates which, for their part, form cooling surfaces, and that the gaseous coolant be conducted directly along the cooling surfaces of the stator plates.
