することによって研磨が行われる。<Prior Art> Conventionally, a fiber holding portion of an optical fiber connector, which is an example of a rod, has a configuration shown in FIG. 2 is a ferrule having a fiber hole 120 in the center, 110 is an end face thereof, and 2 is a fiber which is fixed to the hole 120 with an adhesive. In order to transmit an optical signal, the end surfaces 110 of the two ferrules 1 are butted against each other to form an optical path. In this case, in order to transmit the optical signal efficiently, the optical axes of the fibers 2 are aligned. Of course, this is necessary, but it is also important that the abutting portions be in close contact with each other without any gaps, and that the end face 110 of the fiber 2 be free of any scratches or damaged layers due to processing. For this purpose, the surface of the end face 110 of the ferrule 1 can be polished so that it is perpendicular to the axis of the fiber 2, or
The ferrule 1 must have a convex spherical shape with the top as the top, and there should be no step between the surface of the ferrule 1 and the end surface of the fiber 2.0 Normally, the ferrule 1 is often made of a hard material such as ceramics. In order to process it into a certain shape with high efficiency, after going through 2-3 steps such as rough machining and rough polishing depending on the grade and efficiency of the machined surface, final polishing is performed. It can be finished to a mirror finish of about llB O, 01ILm. FIG. 6 is a schematic diagram of a conventional final finishing method and apparatus. The surface of the surface plate 4 serving as a tool is formed into a predetermined spherical shape, and the holder 3 is formed into a predetermined shape so that the center axis intersection of the ferrule 1 and the center of the spherical surface of the surface plate 4 coincide. The holder 3 causes the end face of the ferrule 1 to perform a so-called grinding motion in which it swings while rotating along a spherical surface of constant t4, and the machining fluid containing diamond particles is pumped between the nozzle member 5 and the surface plate 4. Polishing is performed by supplying the material through the wafer.

加工面の品質において、多数の問題点があった。<Problems to be Solved by the Invention> However, in the conventional technology, the first problem is that when attaching a plurality of optical fiber connectors to the holder 3, the end faces of all 7 errules l are surface plate 4
The work efficiency was extremely poor because it had to be assembled so that it hit the spherical surface of the ball, and because it was done by hand. Another drawback is that it is necessary to attach at least two wooden dummies even when processing only one tree.The motion form of the zero-order holder 3 is complex as described above, making it difficult to speed up the motion. In addition, since the surface plate 4 is made of tin, the machining pressure and circumferential speed are limited, high machining efficiency cannot be achieved, machining takes a long time, and the spherical surface plate wears out. Once deformed, a separate dedicated device is required to correct the deformation, which poses a problem of requiring time and effort. In addition, regarding the state of the end face of the fiber 2 after finishing processing, processing using diamond particles leaves scratches and processing distortions, which can cause deterioration of the propagation characteristics. performance, processing efficiency,
There were many problems with the quality of the machined surface.

研磨微粒子によって加工がなされる。FIG. 1 is a detailed diagram of the present invention, in which 6 is an elastic film material such as a resin film, 7 is a ring-shaped member for fixing the outer periphery of the elastic film material 6, and 8 is a threaded portion. , 9 is a rotating surface plate having a ring-shaped protrusion 910, and lO is a ferrule holding portion. FIG. 1 shows the machining state in this embodiment, and the configuration of the apparatus and the machining method will be described in detail below. To form the device, first, the outer circumferential portion of the disc-shaped elastic film material 6 is clamped and fixed to the ring-shaped member 7 by screwing or adhesive. In this state, the surface of the elastic film material 6 has some sagging.Next, when the material in the above state is screwed into the rotating surface plate 9 by screwing the threaded part 8, the elastic film material 6 in Fig. When the surface of the material 6 comes into contact with a link-like protrusion 910 provided on the rotary surface plate 9 and is further screwed in, the elastic film material 6 is pushed up by the protrusion 910 . here,
Since the elastic film material 6 is an elastic body and the outer peripheral portion is fixed, the pushed-up portion expands like a diaphragm, and a good planar state is obtained.
This is used as a rotating surface plate. As shown in FIG. 1, this processing method using a rotating surface plate supplies an abrasive to the end surface of the ferrule 1, which is clamped by the ferrule holder 10 and is rotating, through the nozzle member 5. By bringing them into contact with each other, processing is performed by the abrasive particles contained in the abrasive mixed between the end face of the ferrule l and the surface of the elastic film material 6.

そして加工初期段階では圧力分布は（ｂｌ）のように、
フェルール１端面の中心部及び外周部が接触するため、
高い加工圧力が生じ、先にこの部分の加工が行われる。Normally, the ferrule 1 is made of a hard material such as ceramics, and the abrasive particles are also made of a hard material, so the contact between the two is on a microscopic surface close to a point contact, and when pressure (processing pressure) is applied here, The concentrated stress action causes micro-fractures, resulting in polishing. On the other hand, since an elastic body is used as the tool material on the side where the elastic film material 6 and the abrasive particles are in contact, the machining pressure is absorbed by the elastic action, so it is not machined, and when the machining pressure is removed, the tool Since the surface returns to its original plane and is not machined, there is extremely little tool wear. Figure 2 shows, as an example, the end face of ferrule 1 formed into a conical shape in the pre-machining process. This figure shows the contact pattern 7g (a) between the end face of the ferrule l and the tool surface of the elastic film material 6 during finishing processing, and its pressure distribution (111) and (b2), when the pressing force δ is applied. The cross-sectional shape of the bony body film material 6 forms an arc shape as shown in (a) at the contact part.
At the initial stage of processing, the pressure distribution is as shown in (bl).
Since the center and outer periphery of the end face of ferrule 1 are in contact,
High processing pressure is generated, and this part is processed first.

の効果が得られる。As the processing progresses, the pressure distribution changes as shown in (b2), and finally, the pressure distribution becomes uniform along the arc of the elastic film material 6, and at this stage, the end face of the ferrule l is aligned with the intended purpose. A convex spherical state is obtained. Moreover, the same effect can be obtained even if the end face of the ferrule 1 after the pre-processing is not a conical face but a flat face.

果が得られる。FIG. 3 shows the results of an experiment regarding the step amount H between the ferrule 1 and the end face of the fiber 2 when the value of the pressing amount δ for applying processing pressure was changed. The machining time at this time was kept constant at 1 minute, about 1/20 of the conventional machining time, and 5i02 particles were used as the abrasive particles. Regarding the quality of the machined surface processed under the above-mentioned optimum processing conditions, as shown in the measurement example in Figure 4, the surface roughness of the end face of the fiber 2 is R□, with a high precision of less than 0.005 g m. It is already known that machining using 5i02 particles does not cause machining distortion, so it is possible to obtain a high-quality machined surface, and the machining time and machining time are shorter than with conventional techniques. There was an improvement in surface quality. Although a resin film was used for the tool in the embodiment, the same effect can be obtained even if metal foil is used as the elastic rotary tool.

By doing the following and improving the quality of the processed surface, the propagation characteristics of optical signals can be improved by more than 10 times. In addition, since high precision is not required for attaching the optical fiber connector to the holder, the mechanism can be simplified and the attachment can be simplified. However, by arranging multiple holders concentrically,
It is possible to process a plurality of items at the same time, which allows efficient processing and can be applied to automation of equipment.
