METHOD FOR MANUFACTURING A PIN PROVIDED WITH A SPHERICAL END PORTION FOR ENGAGING A BALL JOINT

摘要

A manufacturing method is described for a pin (1) provided with an essentially spherical end portion (3) for engaging a ball joint; the manufacturing method comprising the steps of: plastically deforming a rough element so as to manufacture an elongated main portion (2) and the end portion (3) of said pin (1) ; and performing a finishing operation on a peripheral portion (8) of said pin (1) for reducing roughness of the peripheral portion (8) itself; a metal plate disk (10) is used as rough element in said plastic deformation step.
