<p>An apparatus and a method for reducing the outside diameter of thin-walled, relatively soft, metal tubing (10) by using a deformation head, having relative axial movement, comprising a plurality of symmetrically radially spaced rollers (11), each having an arcuate surface (14), that engages the tubing (10) to plastically deform same. Variations in tubing profile and repeatability thereof can be produced in conjunction with a numerical control system. An optional feature of the apparatus is a suitably located cutting tool (15) used to remove material from tubing wall thickness (16) to produce finished wall thickness (17).</p> |
