摘要：
The invention pertains to a special process and devices for the production preferably by machining of workpieces with non-circular outer and inner contours such as squares, hexagons, ellipses, polygons and the like, or eccentric circular bores and/or tappets. In the claimed process, the workpiece is rotated at constant angular velocity while a tool (e.g. the blade of a lathe tool) set eccentrically in relation to the workpiece is moved without rotating about its own axis at controllable speed in a circular path, workpiece and tool being moved towards one another in cycles with the appropriate advance. This ensures that apart from a small cuttings volume for each advance, very narrow tolerances can be set. The associated device, which has a special gear and optionally an integrated cross slide unit, gimbal-mounted yaw head or eccentric spindle, can be used as a compact tool unit for rotary and milling machines and the like.
