FIELD: machining of metals. SUBSTANCE: device may be used for machining of metals by surface plastic deformation. It may also be used for machining of short round billets. Device has abrasive wheel and deforming member positioned on cantilever holder and connected rigidly into machining assembly. Cantilever holder is arranged coaxially with billet secured in chuck with possibility of its swinging in it. Deforming member is placed inside billet in machining zone. Line feed drive is coupled to machining assembly or chuck. In process of machining, round billet-bending has no effect on amount of metal removal and its provides for constant width of wall over perimeter and length of billet. EFFECT: enhanced efficiency. 3 cl, 2 dwg
