Title: Method of manufacturing ferrule
Inventor: TANAKA TETSUO
IPC: G02B6/36
Filed: 2000-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a metallic ferrule having the excellent concentricity and circularity of an inner diameter and outer diameter. SOLUTION: A rod-shaped electroformed body is manufactured by electrodepositing metal to a wire by an electroforming method so as to expose both ends of the wire. Before the wire is removed from the resultant electroformed body, the outer peripheral part of the electroformed body is ground or machined while the electroformed body is rotated around the wire as a central axis (main axis) in the state of supporting the both ends of the wire. The wire is removed from the electroformed body and the electroformed body is cut to a desired length, by which the cylindrical metallic ferrule is obtained. Since the resultant ferrule is worked in the outer diameter around the wire delineating its inner hole as the central axis (main axis), the coaxiality is extremely high with the inner hole (through-hole) and the circularity is high as well.
