A technology of producing hollow railroad axles by screw piercing and radial forging is developed. The design of hollow axles and the production technology are described. The sequence of piercing and forging operations is presented. Trial rough axles were produced. Their mechanical properties are tested, and the test results are compared to the requirements to solid axles.
