FIELD: machine building.
SUBSTANCE: machining of the rotating billet by the spherical deforming element is performed, the element has hardness exceeding hardness of the billet material. The spherical deforming element is installed on the support balls in the acoustic concentrator, the lubricating and cooling liquid is supplied via the axial channel. At that deforming element and lubrication and cooling liquid are subjected to amplitude or frequency modulated oscillations at ultrasonic frequency.
EFFECT: increased productivity, reduced deforming force, improved heat removal from machining zone, and residual stresses are created.
