FIELD: machine engineering, namely operations for shaping surfaces of cone and shaped rollers, precision bearing races and so on. SUBSTANCE: method comprises steps of deforming blank by three rolls mounted on mutually parallel axles. Axial section profile of said rolls corresponds to that of ready article. Several blank are deformed simultaneously. Then said blanks are pushed by distance equal to length value of one blank through groove with intake portion made in driven roll along its axis. EFFECT: enhanced efficiency. 2 dwgy |
