The article proposes the technology of cross-wedge rolling (CWR) of rough wagon axles and new equipment for its realization. Some theoretical bases for rolling of such axles have been considered; their high running ability has been confirmed at the expense of deformation welding of microcavities and microcracks in their surface layers and generation of compression stresses in them; and it finally leads to an increase in fatigue strength of the axles. The new method enables a significant increase in processing speed, rough axle accuracy, a decrease in allowances of forged pieces, in metal consumption and in labour input in machine working of rough wagon axles.
