METHOD AND APPARATUS FOR MANUFACTURING BODIES PROVIDED AT ONE OF THEIR ENDS WITH A SURFACE OF REVOLUTION HAVING THE AXIS ALIGNED WITH A PREDETERMINED AXIS OF SAID BODY

摘要

Method for manufacturing a body provided at one of its ends with a surface of revolution having the axis aligned with a predetermined longitudinal axis of said body and in particular a ferrule (12) for expanded beam connectors (10) provided at one end with a taper cavity (30) whose axis is aligned with the axis of the through hole (16) wherein the end of an optical fiber (14) is housed. The alignment of the axis of the surface of revolution, for instance the taper cavity (30) obtained by a turning operation at the end of the body, for instance a ferrule (12), with any predetermined axis of the body, for instance the axis of the through hole (16) for housing the optical fiber (14), being obtained by applying said body in a projecting manner on a rotating shaft (22) detecting the free oscillations at the end of said body (12) with respect to the predetermined axis of this latter and imposing on said body (12) opposed oscillations adjusted in phase and amplitude so as to eliminate substantially the said free oscillations and to obtain subsequently the surface (30) of revolution by a turning operation.
