Abstract (en)
The production process is for a hollow-shaft base body. The outer surface (4a, 4b) of a cylindrical blank is deformed to produce a preset diameter transition in the initial base body (2). The base body is then deformed on the outer surface and the inner surface (6) incrementally, using transverse conical rolls, to produce the finished base body (8).
