DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a cutter wheel structure and method for cutting glass, and more particularly to a cutter wheel structure having a cutting edge between a blade edge and a cutter wheel substrate. And its manufacturing method 冋 Thickness [Prior Art] ® 77-round cutting method is based on the use of higher hardness materials, so it can be used in a wide range of applications, such as glass cutting, wafer cutting, circuit board cutting, 10 medical cutting instruments, Chemical mechanical polishing (CMP) dressing discs, household cutting tools, special electrodes, metal composite heat sinks and grinding wheel repairs. The traditional cutter wheel design is mostly made of the same hard material, and its structure includes a cutting wheel with a certain thickness, each of which has a torus on both sides, and the outer diameter of the torus extends as a cutting ring end as a knife. The cutting end of the wheel can cut glass, wafers, etc. ❹ Moreover, the manufacture of the conventional cutter wheel, except that it is made of the same hard material as described above, causes the blade surface to be too light/month after the grinding process. Therefore, when cutting the surface of the glass or the substrate, the cutter wheel will Sliding occurs, so that the glass surface cannot produce effective cracks, which is easy to cause breakage of 20 glass and increase production cost. Japanese Laid-Open Patent Publication No. JP2007-031200 discloses a method of using a laser or a grinding method to cut a layer of iron to form a bevel of a diamond layer, and the two bevels form a V-shaped edge. The laser illuminates the diamond layer to create streaks that prevent the cutter wheel from sliding over the glass surface, and the force exerted on the tool will become a vertical force in the direction of the glass. However, JP2007-031200 uses a sintered diamond to form a diamond film, which is costly to produce and cannot manufacture a large number of required cutter wheels. In addition, the German patent DE19753092 discloses a method of depositing a polycrystalline iron layer on the surface of a cutter wheel by a chemical deposition method. However, DE19753092 forms a CVD diamond layer directly on the grinding wheel after the grinding, so that it is formed on the surface of the cutter wheel. A layer of diamond of uniform thickness. In addition, the patent JP6219762 discloses a diamond plating layer (1-10μιη) formed on the surface of the cutter wheel by a CVD film forming method. The diamond plating layer has diamond particles, and the material of the cutter wheel base is made of super hard. The alloy 'such as W or 'vto' is composed of JP6219762, which is first cut and ground into a cutter wheel structure, and then a carbon stone layer having a uniform thickness is formed on the blade portion. In view of the above, since the conventional cutter wheel substrate and the diamond plating layer have a fixed distance, the hardness of the blade portion is insufficient, so that the cutter wheel is not easily penetrated into the glass surface during cutting, which affects the cutting quality and efficiency. Therefore, there is still a need for a cutter wheel and a method of manufacturing the same that can improve cutting efficiency and quality, effectively reduce manufacturing costs, and are easy to operate. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a cutter wheel structure which can improve the impact resistance, forward and lateral support forces of the cutter wheel. Another object of the present invention is to provide a cutter wheel structure which can effectively improve cutting quality and efficiency.
