ABSTRACT:
The invention relates to a method for the manufacture of a rotationally symmetrical part, particularly a vehicle wheel. The starting material is constituted by a circular blank preform, which has a substantially radial base and a connecting, axial shoulder. The shoulder is firstly rolled out by spinning rollers axially on either side of the base to a first web and a second web. At least one of the two webs is spun against a spinning chuck. Subsequently the outer contour of the webs is finally shaped and calibrated in the outer regions.
