A method for making rotors for screw-type machines with a plunge-cut turning method in which an approximately rectangular groove is formed approximately at a center of a work piece with trilateral machining, a groov e is cut radially deeper by trilateral machining until a predetermined groove depth h as been reached, the profile flanks are shaped by bilateral machining, and the groov e depth is increased with a recessing tool. |
