The conductive wheel is formed by an upper guide wheel and a lower guide wheel according to their axial center, the upper guide wheel and the lower guide wheel. Each of the inclined faces pre-set on the circumference of the opposite faces intersects to form a groove having an included angle of at least 9 inches. Accordingly, the conductive wheel has the characteristics of easy assembly, manufacture, and processing, and the upper guide wheel and the lower guide wheel can be selected according to the size of the grinding line pole. A further object of the present invention is to improve a bobbin structure in a conventional wire discharge grinding system for positioning a reel type grinding wire pole, the bobbin structure having the characteristics of convenient pick-and-place grinding wire reel :By. Another object of the present invention is the adjacent position setting of the bobbin structure of the pay-off in the wire discharge grinding system - the hub 'the hub adjusts the height of the discharged grinding pole to keep it at a predetermined horizontal position through the conductive wheel According to the movement stability of the grinding line. - a wire discharge grinding system having a conductive wheel for supporting and moving the grinding wire pole to be close to the microelectrode of an electric discharge machine; the above-mentioned conductive wheel is fixed relative to the axis on a conductive shaft - an upper guide wheel and a lower guide wheel; each of the upper guide wheel and the lower guide wheel intersect with a predetermined inclined surface on a circumference of the opposite surface thereof to form a groove having an inner angle of at least 9G, and the groove is used for the groove To receive the grinding line pole. _[Embodiment] The central idea expressed in the above description of the invention is described in the following. The various items and their amounts of deformation or displacement in the embodiments are drawn to the proportions exemplified in the description and not to the proportions of the actual elements. For example, in the second, third and fourth figures, the present invention relates to a wire discharge polishing system comprising: a first bobbin 20 ′ for positioning a grinding line pole reeling shaft and performing a paying action of the grinding line pole 1 。. A second bobbin 25' is used to position a grinding wire take-up reel and perform a wire-wound wire 6 M338126 action. A conductive wheel 30 is used to support the polishing wire 100 to be adjacent to the microelectrode 200 of the electrical discharge machine. (As shown in Fig. 8) A plurality of grinding wire transfer rollers 40 and a force roller 50 are used to maintain the tension of the polishing wire pole 1 , and to stably convey the movement of the polishing wire pole 100. A hub 60 is located adjacent to the first bobbin 20 for adjusting the payout height of the grinding wire 100 to be stably passed through the conductive wheel 3 at a predetermined horizontal position, thereby improving the grinding k The stability of the movement of the pole 100.第三 For example, in the third, sixth, seventh, and eighth figures, regarding the above-mentioned conductive wheel 3, an upper guide wheel 32 and a lower guide wheel 33 are fixed to a conductive shaft 31. The upper guide wheel 32 and the lower guide wheel 33 are each intersected by a predetermined inclined surface 321 , 331 on the circumference of the opposite surface to form a groove 34 having an angle of at least 90 degrees, and the groove 34 is for receiving the polishing line pole 100 ′. The grinding wire pole 1 is in point contact with the groove 34, and the grinding wire pole 1 〇〇 can be stably moved in the groove 34, and is also suitable for the grinding wire pole 1 of different diameters. The groove 34 has an included angle of 9 degrees or more and is 90 to 160 degrees. Preferably, the horizontal component of the grinding wire 100 can be reduced according to this, so that the problem of pressing the grinding wire 1 in the groove 34 can be avoided, and the movement of the grinding wire can be maintained. Smooth. In addition, in the present case, the upper guide wheel 32 and the lower guide wheel 33 are combined to form the conductive wheel 30 according to their axial centers. The utility model has the characteristics of easy assembly, manufacture and processing, and the upper guide wheel can be selected according to the size of the grinding line pole. 32 and the lower guide wheel 33. For example, in the third, ninth, and tenth drawings, the circumferential positions of the upper guide wheel 32 and the lower guide wheel 33 are respectively provided with at least one slot 322, 332 which is opened in the axial direction, and the slot 322, 332 is When the upper guide wheel 32 and the lower guide wheel 33 are oppositely combined, the upper and lower sides are accurately opposed to each other to form a space for the microelectrode 2 to penetrate. The application of the slots 322, 332 is related to the processing steps of trimming the microelectrodes. It is known that the step of trimming the microelectrodes 2 大致 generally includes trimming, roughing, and finishing of the end face M338126. The end face trimming is performed by moving the microelectrode 2 directly above the polishing wire electrode 1 to perform end surface trimming of the microelectrode 200 to correct the end surface of the microelectrode 200. The roughening of the microelectrode 2〇〇 is performed, and the radial feed of the microelectrode 200 can be increased at this time, and the grinding wire pole 1〇0 removes the rotational eccentricity of the microelectrode 2〇〇. The finishing of the microelectrode 200 reduces the discharge current to below ιΑ, and then divides the micro-electrode processing according to the actual demand, and can also perform the indexing processing of the microelectrode 2〇〇, trimming the shaped microelectrode, and processing The process can be used to measure the electrode size on the line and observe the processing status through the CCD microscopic measurement system. Most of the trimming has been done with _, three veins, square columns, needles, etc. • Microelectrodes are the main forming targets. Therefore, the slits 322, 332 opened in the conductive wheel provide space for the polishing wire 100 and the microelectrode 200 to change relative positions for processing. As shown in the second and fifth figures, the hub 60 is located adjacent to the first bobbin 2〇, the hub 60 has a tapered opening 62, and a linear slot connected to the small-diameter end of the tapered opening 62. 63. The tapered P and 62 are oriented toward the first bobbin 2'' with the opening of the large diameter end, and the linear groove 63 faces the direction of the conductive wheel 30. The tapered opening 62 is configured to receive the grinding wire pole 1 放 discharged by the first bobbin 2 〇〇, and adjust the height of the grinding wire pole 彳 (10) by the linear groove 63 to keep the _ pre-horizontal position stable Through the φ conductive wheel 30, the motion stability of the polishing line pole is improved. As shown in the third figure, the first bobbin 2〇 and the second bobbin 25 have the same structure, and are characterized in that they have a re-dischargeable upper stop tab 26 and a lower stop tab 27 for the operator to The grinding wire take-up spool or the grinding wire pole take-up shaft is sleeved outside the vertical shaft or taken out from the vertical shaft.
