Abstract: In a machine tool with an inclined machine bed in which two independently movable cross slides are provided, which carry turret heads with tool receivers automatically interchangeable tool grippers are adapted to bring the tools in predetermined positions into respective tool receivers.

Abstract: The invention comprises a tool turret for a turning machine whose operational axis has a wider spacing from the bed of the carriage than the spindle axis of the turning machine. The tool turret has an inner rim with inner turning tools and an outer rim with outer turning tools, the inner and outer turning tools being angularly offset in relation to each other. In order to bring the inner and outer turning tools into operating position during the stepwise further movement of the turret, successive operational angles must be variable. Because of the wider spacing of the operational axis from the bed of the carriage, the turret disc carrying the tools can be made larger with the result that more tools can be provided thereon or the spacing between the tools can be enlarged. The changeover with unequal angles can be accomplished by means of a regulated direct current motor, the operational angle being fed into the regulation circuit as the desired value.
