A machine tool, designed for volume production, comprises a head with a single spindle, rotatably mounted about an axis, inclined by 45 DEG in respect of the horizontal working plane of the machine. Automatic control means allow said head to take up at least the two positions corresponding to the horizontal spindle position and to the vertical position, while a single device is provided for the automatic change of the tools, adapted to change the tools on the spindle of said head, when the latter takes up one of said two positions.
