FIELD: strengthening of outer cylindrical and flat surfaces by plastic deforming. SUBSTANCE: tool includes holder with spring-loaded cooled roller and with electric current lead for connecting roller with electric current source. Roller is provided with detachable deforming-strengthening member in the form of ring. Tool also includes system for controlling and sustaining temperature of working surface of member in desired range. Deforming-strengthening member is secured to roller mounted on shaft by means of sleeve and copper ring, both carrying lids. Shaft, lids, copper ring and sleeve have openings for circulation of cooling liquid. EFFECT: enhanced stability of working process, increased useful life period. 4 cl, 2 dwg
