FIELD: technological processes.
SUBSTANCE: invention relates to recovery of worn splined and toothed profiles on shafts. Performing drilling of cylindrical hole, axis of which coincides with geometrical axis of billet. Billet is heated to up to forging temperatures. Metal is moved from underlying layers of the shaft by moving the working tool in the axial hole of the shaft. Axial ultrasonic oscillations are applied on the working tool, simultaneously with its movement along the hole. Roller is used to roll shaft profile.
EFFECT: higher tool durability.
