ABSTRACT:
A method and an apparatus for grinding the foremost end surface of a ferrule integrated with an optical fiber wherein the foremost end surface of the ferrule is stepwise ground together with the optical fiber to exhibit a predetermined radius of curvature. The grinding process is practiced by way of three steps, i.e., a rough grinding step, a medium grinding step and a finish grinding step. A base board and abrasive grains on an abrasive film required for the medium grinding step have a hardness higher than that of those for the rough grinding step, and a base board and abrasive grains on an abrasive film required for the finish grinding step have a hardness higher than that of those for the medium grinding step. The foremost end surface of the ferrule is projected downward of the lower surface of a holder by a predetermined quantity before the rough grinding step is started. In addition, after completion of each grinding operation, the holder is displaced away from the base board so as to allow the latter to be replaced with another one. To assure that the foremost end surface of the ferrule exhibits a predetermined radius of curvature after completion of each grinding operation, it is necessary that each base board is made of an elastic material. A plurality of ferrules can be ground in substantially the same manner.
