METHOD AND MACHINE FOR PRODUCING A ROTOR OF AN ECCENTRIC SCREW PUMP

摘要

The present invention relates to a method and a machine for producing a rotor of an eccentric screw pump, with which or in which the shape of the rotor is produced by a peeling process followed by a smoothing process of the surface. The object of the invention is to make the smoothing process less time-consuming and, in addition, more cost effective with this method or with this machine. This object is solved with a method in which the smoothing process is accomplished by smooth-rolling. The machine for carrying out the method has a machine bed (3) on which a peeling head (9) and a smoothing head (7) are arranged so as to be axially movable for processing the rotor (2).
