ABSTRACT:
A machine tool comprises a spindle that rotates about a spindle axis and that comprises a receptacle for toolholders. There is further provided a number of tool changers distributed around the spindle, the gripper arm of each tool changer carrying a toolholder that can be transferred, by means of the gripper arm on which it is mounted, between a magazine position spaced from the spindle above the receptacle, and a working position on the receptacle. The toolholders are arranged in their magazine position with their longitudinal axes extending at an angle relative to the spindle axis so that they point away from the spindle obliquely in downward direction.
