This article examines the technology of cross-wedge rolling (CWR) in the production of railway axles, as well as new equipment for its realization. Some theoretical bases for the rolling of such axles have been considered and confirmed, resulting in axles of higher fatigue strength. The new method enables a significant increase in processing speed; improved rough axle accuracy; and decreases in scrapped pieces, metal consumed and labor content.
