Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an electrochemical process, which reduces manufacturing costs, reduces fabrication time, and extracts an electrode and a method for fabricating the same. In particular, it refers to an electrochemical process with high precision [0002] [Prior Art] According to the bearing, the bearing is a common mechanical component, which is widely used in various fields of products. However, since conventional bearings generate friction in contact with the shaft, the service life is limited and noise is generated. Based on the above shortcomings, hydrodynamic bearings have been developed in recent years, which effectively solve the shortcomings of conventional bearings. The products that use dynamic pressure bearings on the market are commonly used in hard disk drive motors, optical disk drive horses, multi-face mirror motors and computer fan motors. They are widely used in information storage media, laser printers and computer mainframes. device. Nowadays, with the rapid development of the computer information industry and digital home appliances, the precision required by the spindle motor is increasing. Under the design trend of high speed, small volume, low noise, long life and high precision, the dynamic pressure bearing plays an improvement. One of the important roles of small main motor characteristics. At present, the dynamic pressure bearing is different from the fluid, and the occasion and the machining precision are also different. The fluid dynamic bearing technology uses the shaft to rotate in the bearing, and the inner peripheral surface of the bearing sleeve is provided with a plurality of grooves, and The lubricating fluid is injected into the gap between the shaft and the bearing sleeve, so that the lubricating fluid forms a pressure oil film between the shaft and the bearing when the shaft rotates, thereby avoiding vibration and noise caused by contact with the boring surface, and the service life can be improved. In the initial stage, the way of forming the groove on the surface of the dynamic pressure bearing is mostly by mechanical force or casting method, but the conventional process will cause the edge of the groove to form a convex shape, which will reduce the performance of the bearing. Therefore, 099141820 Form No. A0101 Page 3 of 26 〇992〇72675-〇 201224225 Nowadays, the groove of dynamic pressure bearing is made by electrochemical machining to solve the above shortcomings. When the groove of the inner peripheral surface of the dynamic pressure bearing is generally produced by electrochemical machining, a machining electrode must be fabricated for electrochemical processing. For example, as shown in the Republic of China Patent No. 1500834, the surface of the electrode is usually processed and patterned. It is complementary to the groove on the inner peripheral surface of the bearing. However, the method for forming the surface pattern of the processed electrode is generally formed by mechanical force removal, so that the surface of the processed electrode forms a protruding portion opposite to the groove shape, and the portion that does not need to be electrochemically processed is a concave portion, and The recess is filled with an insulator to prevent the recess from electrochemically machining the bearing surface, and the inner peripheral surface of the bearing is electrochemically processed by the surface protrusion of the machining electrode to form a surface on the inner peripheral surface of the bearing. The groove corresponding to the protrusion of the surface of the electrode is processed. In addition, as in the Republic of China Patent Publication No. 97142494, which is another processing electrode for the dynamic pressure bearing processing process, the electrode substrate is covered with an insulating layer on the surface of the electrode substrate, and then a part of the insulating layer is removed to be in the insulation. Forming a penetrating portion having a specific pattern on the layer, and plating a conductive layer on the surface of the electrode substrate on which the penetrating portion is exposed, thereby forming a processing electrode of the electrochemical processing process, and thereby utilizing the conductive layer of the electrode The layer pattern is electrochemically processed on the inner peripheral surface of the bearing. The above-described method of fabricating the electrochemically processed electrode is to mechanically remove the unnecessary material on the electrode substrate by using a cutter to form a concave portion, and then fill the concave portion with an insulating material or a conductive material. However, when machining with a mechanical force to remove a tool, a precision four-axis machine, a fine tool, and a high-speed spindle are often required, and the process length is long and a lot of processing time is required, because the above-described process has a higher technical level. There are basic processing costs 099141820 Form No. A0101 Page 4 / Total 26 pages 0992072675-0 201224225, and the thermal method effectively reduces the electrode processing cost, even if only the electrode of the simple characteristic pattern is needed, there is still processing cost and process time. Long, low process flexibility and other shortcomings. In addition, when the width of the groove on the bearing is small, for example, 1 mm (_) or less, the machining surface of the electrode substrate is often burred due to the low rotation speed or wear of the tool spindle, so that the machining electrode is used. The shape of the bearing groove formed by electrochemical machining is fatigued, resulting in wasted processing cost and time, and reduced bearing accuracy. ◎In view of the above problems, an electrochemical force electrode and a method for fabricating the same have been proposed, which not only can improve the above-mentioned conventional disadvantages, but also can reduce the manufacturing cost, reduce the production phase SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an electrochemical processing electrode and a material, which by (4) at least - the insulation of the wire anode unit ^ need to remove the electricity, the element, so The structure is simple and the production method is simple, the production time is increased, and the manufacturing cost is increased; the production cost is reduced, the elasticity and precision of the electrode are reduced. One of the objects of the present invention is to provide an electrochemical processing method for the bran, and to perform electrochemical processing by using a wire electrode fixed with a wire, the wire being fixed to the insulation of the processing electrode and the wire being fixed to the processing electrode: The exposed electrode is exposed on the insulating surface. Therefore, the processing electrode is made of a single piece and has high precision. Therefore, the chemical processing of the material of the hole (four) edge surface can be used to improve the shape of 099141820. The electrode unit has 'there is an electrode unit and at least the 5th S/4t edge surface of the form number A〇l01, and the wire is fixed on the surface of the insulating material 26 page 0992072675-0 201224225 and exposed on the insulating surface. Since the electrochemical processing electrode of the invention has a simple structure, the manufacturing method is easy, and only the fixing wire needs to be fixed on the insulating surface, so that the manufacturing cost can be greatly reduced, the manufacturing time can be greatly shortened, and the processing difficulty of the electrode can be greatly reduced, and Improve the elasticity and precision of the fabricated electrodes. Further, the electrochemical processing electrode of the present invention further comprises a bonding layer attached to the insulating surface to fix the wire to the insulating surface. The present invention further provides an electrochemical processing method, which first provides a processing electrode to which at least one wire is fixed, the wire is fixed on an insulating surface of the processing electrode, and exposed on the insulating surface; and then the processing electrode is penetrated into a workpiece One of the shaft holes, and the inner peripheral surface of the shaft relative to the shaft hole of the workpiece; after that, an electrolyte is filled between the workpiece and the processing electrode; then, the two poles of a power unit are respectively connected to the wire and the workpiece, Thus, the workpiece is electrochemically processed to form a groove on the inner peripheral surface of the shaft hole of the workpiece. [Embodiment] [0004] For a better understanding and understanding of the technical features of the present invention and the achievable effects of the present invention, please refer to the preferred embodiment and the detailed description, as follows: Please refer to the first drawing, which is a schematic diagram of an electrochemical processing electrode according to a first preferred embodiment of the present invention. As shown, the electrochemical processing electrode 5 of the present invention comprises an electrode unit 10 and at least one wire 11, and the electrode unit 10 has an insulating surface. The electrode unit 10 of this embodiment comprises a conductive substrate 15 and an insulating layer 14, and the conductive substrate 15 can be a metal conductor. The surface of the insulating layer 14 is an insulating surface, and the insulating layer 14 is disposed on the surface of the conductive substrate 15 to insulate the surface of the conductive substrate 15. The insulating layer 14 is 099141820. Form No. A0101 Page 6 of 26 0992072675-0 201224225 is fixed on the surface of the conductive substrate 15 by immersion plating, and its hardness and strength are larger than those of the adhesive. The wire 11 is disposed on the insulating surface of the electrode unit 10, that is, on the surface of the insulating layer 14, and the pattern of the wire 11 disposed on the insulating surface of the electrode unit 10 is determined according to the groove to be formed on the surface of the workpiece, for example, The groove on the inner peripheral surface of the pressure bearing, the wire 11 is complementary to the groove on the surface of the workpiece. The wire 11 of this embodiment is fixed to the insulating surface of the electrode unit 10 in a loop-like pattern to form a spiral pattern. In addition, the electrochemical processing electrode 5 of the present invention further includes a bonding layer 16 attached to the insulating surface of the electrode unit 10, that is, attached to the insulating layer 14 , for fixing the wire 11 to the insulating surface of the electrode unit 10, One preferred embodiment of the bonding layer 16 is an adhesive. Since the wire 11 of the present invention can be directly fixed to the electrode unit 10 in a circumferential manner, the present invention is not necessarily provided with the bonding layer 16 on the insulating surface. The processed electrode 5 of the present invention has a simple structure, and is therefore relatively easy to manufacture. When the width of the groove formed on the surface of the workpiece is less than 1 mm (mm), the present invention may use a wire 11 of less than 1 mm, such as a copper wire, a gold wire, an aluminum wire, etc., and by using a 2-axis or The processing device of the two or more axes fixes the wire 11 on the insulating surface of the electrode unit 10, and rotates the electrode unit 10 by one axis of the processing device, and the other wire holds the wire 11 and moves to fix the wire 11 around the electrode unit. The insulating surface of 10, so that the processing device with the high-speed spindle is not required to drive the fine tool to cut the electrode unit 10, thereby greatly reducing the expensive equipment required for manufacturing the processing electrode 5, the time for finding the multi-axis processing device, and the production time and Cost 〇 As apparent from the above description, the present invention can greatly reduce the processing cost and technical difficulty required to produce the feature pattern of the processed electrode 5. Since the 099141820 of the present invention has the form number A0101, page 7 / 26 pages 0992072675-0 201224225, the machining electrode 5 does not need to be cut in manufacturing, so that the difficulty in making the micro feature pattern is greatly reduced and can be improved. The degree of elasticity of the processing electrode 5 is made. In addition, since the processing electrode 5 of the present invention does not need to be subjected to cutting processing, the processing electrode 5 of the present invention does not have the problem of cutting burrs. Therefore, the machining electrode 5 of the present invention is used for electrochemical processing of the workpiece. The defect rate of the processed surface formed on the groove of the workpiece is reduced, and the forming precision of the groove is improved, thereby improving the precision of the produced workpiece. The processing electrode 5 of the present invention can be applied not only to dynamic pressure bearings, but also to other types of workpieces. Referring to Figures 2A through 2D, which are schematic views of a method of fabricating an electrochemically processed electrode in accordance with a preferred embodiment of the present invention. The manufacturing method of the processing electrode 5 of the present invention first provides the electrode unit 10. This step is first provided as shown in FIG. 2A to provide the conductive substrate 15; then, as shown in FIG. 2B, on the surface of the conductive substrate 15. The insulating layer 14 is provided, and the surface of the insulating layer 14 is an insulating surface, so that the electrode unit 10 has an insulating surface. Then, as shown in FIG. 2C, the bonding layer 16 is coated on the insulating surface of the electrode unit 10, that is, on the surface of the insulating layer 14, to successively fix at least one wire 11 to the insulating surface of the electrode unit 10 (see In the second D diagram), the wire 11 can be disposed on the insulating surface of the electrode unit 10 by means of a ring. The bonding layer 16 has the effect of fixing the wires 11, so that the wires 11 can be firmly attached to the insulating surface and are not easily peeled off. In the present invention, the bonding layer 16 may be disposed on the insulating surface of the electrode unit 10 without directly providing the bonding layer 16 on the insulating surface of the electrode unit 10. For example, the wire 11 is directly wound and fixed on the insulating surface of the electrode unit 10.
