EINRICHTUNG ZUR SPANABHEBENDEN UND DRUCKUMFORMENDEN BEARBEITUNG VON ZYLINDRISCHEN OBERFLAECHEN

摘要

A contrivance for the cutting-deforming of cylindrical surfaces comprises a housing wherein are installed in succession a head with at least two deforming rollers and a tool-holder adapted for movement in a plane perpendicular to the direction of a longitudinal feed. The tool-holder has an opening for passing a workpiece to be machined and accommodates a main pair of cutting tools and at least one additional pair of cutting tools. The cutting tools of the main pair are disposed oppositely in relation to a cylindrical surface under machining and in one plane with the deforming rollers. The deforming rollers are disposed relative to the cutting tools of the additional pair at a distance not multiple of a distance between the main and additional pairs of cutting tools equal to 0.1-1.5 of the value of a set-up size of the cutting tools of the main pair. The nose of one cutting tool is displaced relative to the nose of the other cutting tool of the same additional pair by a value not exceeding the radius of the cutting edges of the cutting tools of this additional pair.
