Verfahren und Vorrichtung zur Herstellung eines mit mindestens einem Stift versehenen, koaxialen Verbindungselementes.

摘要

The invention relates to a method for producing a cylindrical body comprising at least one stud having a cylindrical base portion projecting from its rotating surface in which a cylindrical body blank is produced comprising a peripheral collar of external diameter equal to that of the stud or studs to be obtained, and of width greater than the diameter of the base of the stud or studs to be obtained. Said stud or studs (13) are produced and the excess material from the collar (24) is removed during a single machining operation using at least one machining cutter (14) comprising a hollow shape (15) and rotating about an axis (R3) perpendicular to the longitudinal axis (R1) of the blank (12), by rotatably driving the blank (12) about its longitudinal axis (R1) and by rotatably driving the milling cutter or cutters (14) in the opposite direction about a second axis (R2) parallel to the longitudinal axis (R1) of the blank (12), said milling cutter or cutters (14) having a substantially spherical peripheral cutting surface in contact with the surface of the blank (12).
