ABSTRACT:
A method of manufacture of a rotationally symmetrical part, particularly a vehicle wheel. In this method, the outer circumferential area of a circular blank is upset for forming a material accumulation or gathering and this preferably takes place asymmetrically. Subsequently, the outer circumferential area of the circular blank is radially split using a splitting roll, which forms two legs. The two legs are subsequently given the desired shape by the utilization of spinning rolls.
