Description of the invention (1) [Application fields in the industry] This invention relates to the outer diameter of the ferrule (Ferru 1 e) used in the components of the connector of the optical fiber. Cutting device and cutting method [Known Technology] The main connector components of metal ferrule-type optical fibers use ceramic materials such as ceramics (Zirconia > s), as shown in Figure 5 (a). The cylindrical shape is formed by combining the outer diameter 5, and the optical fiber insertion hole 2, and the end surface 1b 'and the rear end 1c. In order to easily insert the optical fiber into the optical fiber insertion hole 2, the rear end 1c side The optical fiber insertion hole 2 is provided with an inclined chamfered portion 2 a. Therefore, the correct ends of the optical fiber insertion hole 2 of the metal ferrule 1 form 2 c and 2 d in the figure. When the outer diameter of the metal ferrule 1 is machined, the two centering tips support the two ends of the two. c, 2 d to support the metal. When assembling the optical fiber connector using the metal ferrule 1, as shown in FIG. 5 (b), the optical fibers 3a and 3b are respectively inserted into the optical fiber insertion holes 2'2 of the pair of metal ferrules 1, 1 and Insert the split sleeve 4 with the outer diameter of the metal ferrules 1 and 1 as the reference, and insert the optical fiber 3a (3b) through the front end plane 1 b of the metal ferrule 1 and the end face of the optical fiber forming the same plane as the end face. , Is precisely connected to the metal ferrule 1 and the optical fiber 3b (3a), and the optical fiber 3a and the optical fiber 3b are surely connected. At this time, if the center of the optical fibers 3 a and 3 b is shifted or a gap is created at the contact surface, the diameter of one optical fiber is about 1 2 5 μm, which will cause the two connectors to suffer loss of light and other optical characteristics. , Create communication barriers ------- a ----; --- install ----- II — order II —----- line — (Please read the precautions on the back before filling in this page) This paper size applies to China National Standard (CNS) A4 specification (210 X 297 mm) -4- R 4 42 3 5 8 A7 B7 V. Explanation of the invention (2). For this reason, the optical fiber insertion hole 2 of the ferrule 1 and the outer diameter 5 'require extremely high concentricity and cylindricality. Further, in order to easily insert the optical fiber into the above-mentioned optical fiber insertion hole 2 ', a chamfered portion 2a concentric with the optical fiber insertion hole 2 is provided at the rear end face 1 c. Of the ferrule 1. For those metal ferrules 1 that are formed by injection molding, extrusion molding, and stamping, the front end flat portion 1 b and the optical fiber insertion hole 2 are precisely trimmed before inserting the outer diameter of the ferrule, and the optical fiber is inserted. The right angle formed by the hole 2 and the front end flat portion 1 a and the cylindricality of the optical fiber insertion hole 2 are extremely accurately trimmed. Next, the outer diameter of the ferrule 1 is chamfered using the optical fiber insertion hole 2 as a reference. When the optical fiber insertion hole 2 is used as a reference, 'the steel cable is inserted through the optical fiber insertion hole 2 in advance and the appropriate tension is maintained', and then the outer diameter of the metal ferrule 1 is sandwiched between the driving roller and the honing wheel. The metal is driven by the rotation of the driving roller Hoop 1 rotates 1 while honing with a honing grinding wheel 'or supports two optical fiber insertion holes with two centerers 2' Rotate the metal hoop 1 'using a lathe dog at one of the centerers at the same time The grinding wheel performs honing. The above-mentioned honing system using a steel cable is shown in FIG. 6. The main shaft 6 is provided with a main shaft 7 and a driving roller 8 ′ which are freely supported for rotation. The metal ferrule 1 is inserted into a steel cable 30 ′ extending on the main shaft 6. The grindstone table 10 which supports the honing grinding wheel 9 rotatably feeds the honing to the headstock 6. There is also a 10b series, which is used to support the base of the grindstone table 10 which can move freely in the feed direction. However, in the chamfering method where the steel cable penetrates the optical fiber insertion hole 2, the remaining gap between the optical fiber insertion hole 2 and the coaxiality is affected, and a collet is used (please read the precautions on the back before filling this page)

Can be effectively separated by the centerer 2 2 a. The above-mentioned automatic flooding and discharging (1 9), the pressing of the driving roller 8 toward the metal hoop 1, the honing of the metal hoop 1 by the honing grinding wheel 9 (9), the automatic measurement (1 8), and the metal hoop A series of actions discharged can be independently and asynchronously performed on several spindle tables 7. Several spindles are machined using a grinding stone shaft, so the milling device is more compact and smaller. Compared with the conventional single-spindle table / grind table feed-type metal hoop outer diameter turning device, the average productivity per unit time I is increased by about 1.8 times. The inability to achieve twice the calculated production efficiency is due to the addition of the metal hoop for loading and unloading, and the time to feed the grinding stone, which can not achieve zero standby time. Compared with a heavy stone table (diameter 3 Grinding wheels with a degree of 0 Omm) are used to process metal ferrules. Even if the reciprocating motion of several lighter spindle tables is used to process several metal ferrules, the response is fast, which can be said to save energy. In the present invention, 尙 can be operated in other cycles according to the processing conditions, for example: time difference in time, when one of them is cutting, the other is loaded and unloaded with a metal hoop to operate interactively, the waiting time becomes less, and The cutting, loading, and unloading operations overlap in time; the spindle no longer processes the metal hoops with different outside diameters and lengths simultaneously with the straight grinding method (Plunge Gnnding).
