Abstract

In a method of grinding a ferrule, a ferrule is provided having a leading end portion having a surface disposed generally perpendicular to a longitudinal axis of the ferrule. A grinding device is provided having a rotational base, an elastic member disposed on the base for rotation therewith, and a grinding sheet disposed on the elastic member for rotation therewith. The surface of the leading end portion of the ferrule is brought into contact with a grinding surface of the grinding sheet. The base of the grinding device is then rotated until the surface of the leading end portion of the ferrule is ground into a spherical surface. The spherical surface of the leading end portion of the ferrule is then brought into contact with the grinding surface of the grinding sheet so that the longitudinal axis of the ferrule is inclined relative to the grinding surface. The base of the grinding device is then rotated until the spherical surface of the leading end portion of the ferrule is ground into a spherical surface so that the longitudinal axis of the ferrule is inclined relative to a tangent passing through a vertex of the spherical surface.
