摘要： A method for the manufacture of a machine part with external teeth, particularly a starter ring or gear part, by spin forming of a circular blank and inductive heating which makes it possible to form high-quality tooth systems on an outer area of a cylindrical part. A circuit metal blank is fixed between chuck jaws in a spinning device and an end region is heated by at least one induction device and passes into a plastic state. Tools are then infed on either side of the chuck jaws and a forming operation, which includes material upsetting, is performed with a gear-cutting roll to form the external teeth. This is followed by induction heating of the teeth.
