The radial material flow toward the centerline of the workpiece is controlled by the mandrel. Double stepped internal forms: This inside geometry is a further example of the internal forms which can be produced by Rotary Swaging over a Mandrel. Non-circular internal geometries: Swaging over a mandrel can be used to produce a multitude of different internal forms with very close tolerances. Typical examples are internal splines, helical forms, rifling and keyway profiles, square forms, hexagonal forms, etc. Print   Feedback
