FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, to finishing-hardening of bores by surface plastic deformation. Billet is fed in lengthwise and crosswise directions. Sizing mandrel is revolved and pressed against machined surface. Sizing mandrel comprises body with deforming elements with blunt holes made on body end face. Rods are arranged in said holes to reciprocate therein. Deforming elements are secured on rid outer end faces. Packs of plate springs act on rod inner end faces. Mandrel body performs additional return oscillation, driven by ring with cam, fitted on body free end face to come in contact with drum with cams. Deforming elements reciprocate and oscillate radially. Drum is fixed on machine tools.
EFFECT: higher efficiency and quality of sizing.
