Description of the invention (1) Background of the invention 1 1. Field of the invention The present invention relates to a working method and equipment for honing-workpieces on the inner surface side of one of the cup-type honing wheels. 2. Description of Conventional Technology Conventionally, a sleeve of a component known as an optical fiber has an end surface that is processed into a dome (arc) shape by honing. Generally, when a tip end surface of the collar or any other elongated workpiece is processed into a dome shape by honing, the workpiece is honed using, for example, a honing machine as shown in FIG. In the honing machine shown in FIG. 6, a cup-shaped honing wheel 8 is attached to one end of the grinding wheel mandrel 7, and, in order to satisfy the processing, the workpiece end surface 5a of the workpiece 5 becomes a dome-shaped relationship. A chuck 4 at the end of the workpiece mandrel 3 and a cup-shaped honing wheel 8 side of the grinding wheel mandrel 7 are set so that they face each other and incline. To process the workpiece end surface 5a into a dome shape, the workpiece 5 is set in a chuck 4 on the end of the workpiece spindle 3, and the workpiece end surface 5a is honed by an inner surface of one of the cup-type honing wheels 8. The contact point P between the workpiece 5 and the cup-type honing wheel 8 (hereinafter referred to as `` 'Honing Point〃' ') is located on the inner surface of the cup-type honing wheel 8, and a working fluid is supplied to the honing Grind point P. -The above-mentioned conventional honing machine is used because the workflow system is configured to spray the honing point P on the inner surface of the cup-type honing wheel 8 from an outer point of the cup-type honing wheel 8 and has the problems described below. . < Please read the notes on the back before filling out this page) —Order --------- Line Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs

Description of the invention (2) (1) There is a possibility of insufficient supply of working fluid, which leads to a reduction of 硏Grind accuracy. '(Please read back & note *: Matters before filling out this page) During honing, the cup honing wheel 8 rotates at a high speed similar to the workpiece 5, and the end and the peripheral surface of the cup honing wheel 8 are both Covered by an air curtain caused by high-speed rotation. When the working fluid is supplied from the outside of the cup honing wheel 8 in a conventional manner, a portion of the working fluid is rejected by the pressure of the air curtain before reaching the honing point P on the inner surface of the cup honing wheel 8 . In particular, during the repeated use of the cup-type honing wheel 8, the cup-type honing wheel 8 itself gradually wears, and the honing point P gradually shrinks toward the bottom portion of the cup-type honing wheel 8. Therefore, the cup-type honing wheel 8 Edge, as long as the workflow system is supplied from the outside of the cup-type honing wheel 8 in a conventional manner, it will become an obstacle to the supply of working fluid. In this situation, it is more difficult to sufficiently supply the working fluid to the honing point P on the inner surface of the cup-type honing wheel, and the problem of insufficient supply of working fluid becomes more serious. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs (2) and the structure in which the working fluid is supplied from the outside of the cup honing wheel 8 in a conventional manner involves the complicated surrounding structure surrounding the cup honing wheel 8, because A nozzle 19 for supplying a working fluid is provided on the outside of the cup-type honing wheel 8. The entire peripheral space surrounding the cup-type honing wheel 8 cannot be effectively used. In addition, there is a possibility of insufficient supply of working fluid caused by humans. That is, for example, when setting the workpiece 5 on the workpiece spindle 3, an operator may inadvertently contact the nozzle 19 and change the direction of the nozzle 19, so that the working fluid cannot be correctly supplied from the nozzle 19 to the -cup. Honing point P on the inner surface of the profile honing wheel 8.

Description of Invention (3) 1 9 "The contact" will lead to insufficient supply of honing fluid caused by humans. (3) Further 'when the working fluid is supplied from the outside of the cup honing wheel 8 in a conventional manner, it is covered by the The pressure of the air curtain at the end and the surrounding surface is rejected and scattered around the honing machine, thereby destroying the working environment surrounding the honing machine. The invention is described in terms of the problems inherent in the conventional technology, and An object of the present invention is to provide a working method and working equipment which can supply a sufficient amount of working fluid to a honing point on an inner surface of a cup-type honing wheel, which is suitable for high-precision honing, and which can effectively The space around the cup-type honing wheel is used, and the working environment surrounding the honing machine is maintained in a clean state. In order to achieve this object, according to one aspect of the present invention, a working method is provided.
