FIELD: process engineering.
SUBSTANCE: invention relates to machine building and may be used for surface plastic deformation. Revolving billet end surfaces are turned by turning tool and ball-shape forming tool lagged behind cutter vortex in direction of crosswise feed. Forming element is mounted at acoustic concentrator provided with axial channel for lubricant-coolant feed. Ultrasound frequency amplitude modulated oscillations are imparted to forming tool and lubricant-coolant.
EFFECT: lower contact temperature between forming element and billet, better heat removal from turning area.
