Abstract: A single-edged milling tool has a shaft section and a machining section. A face cutting edge is formed on a distal end of the machining section. The face cutting edge extends radially from an outside end at an outer peripheral edge to an inside end close to the axis of rotation. The face cutting edge has an outer peripheral planar portion at a constant planar distance to a reference plane extending perpendicular to the axis of rotation. An oblique portion connects the planar portion to the inside end. The oblique portion of the face cutting edge is closer to the reference plane than the planar portion. The distance of the face cutting edge from the reference plane in the oblique portion diminishes continuously starting out from the planar portion to the inside end of the face cutting edge.

Abstract: An automatic machine tool, particularly for producing a dental prosthesis of exact three-dimensional shape, includes a machining unit (200), a workpiece feed unit (300), a tool feed unit (400) and an operating and control unit. The machining unit (200) includes a machining tool (430) that is displaceable in three spatial directions and has a cardanic workpiece holder receptacle (210) that can be pivoted about two axes, wherein the workpiece holder receptacle (210) is arranged vertically and the machining of the workpiece is carried out in vertical arrangement so as to allow the dropping of chips.
