- i - ABSTRACT of the DISCLOSURE. The invention relates to a procedure and means to realise a hub from a metal disc or similar according to the invention, a disc (6), in which a central hole has already been bored, is set in motion about its own axis. Internally to the said central hole a tool (16) is inserted comprising a circular cutter (17) formed so as to penetrate into the width of the disc (6). The tool (16) is pressed against the edge of the central hole and is made to advance radially in such a way as to produce the cutting and separation, or opening, of the disc (6) into two sheets, or leaves (18) which are then made to divide and are arranged so as to generate tracts of cylindrical surface which are coaxial with the disc (6) rotation axis.
