Apparatus for the machining of cylindrical surfaces

摘要

An apparatus for the machining of cylindrical surfaces on machine tools comprising headstock and tailstock centers to support the work placed therebetween, a tool head, and a head with deforming rollers spaced equidistantly apart in a circumferential direction. The heads are consecutively arranged in a housing fitted to the carriage of a machine tool. A portion of the tailstock center that, in operation, is face to face with the work serves as the guide for the deforming rollers and has a diameter virtually equal to the diameter at which the deforming rollers are set. Its end next to the work is adapted to accommodate the point of the tool in a position preparatory to machining.
