Internal, -,,. The cutter wheel applies a certain pressure so that the recessed portion cannot be cut into the glass mark. The adjacent cut mark can generate a crack line under the stress effect 3 201121909 and is connected by the split line so that the glass is cut and broken. However, the most important problem in the cutting of these types of cutter wheels is that the cutter wheel will be filled with the glass micro-powder generated when the cutter wheel is cut, causing the cutter wheel to be clogged and the cutter wheel loses its cutting ability. The portion of the structure that is in contact with the glass 11 causes severe damage to the crack generated by the cutting, as shown in Fig. 7(d).

In the case of cutting the glass, in addition to the generation of the slits 12, a radial crack line 13 as shown in Fig. 7 (d) is produced. For the processing method of the cutter wheel, the method of laser processing proposed by the applicant's patent ZL200410104603.2 and another patent CN2〇〇68〇〇〇3956〇, the direction of the laser beam is opposite to the face of the cutter wheel疋 Vertical. When the microstructure is processed at the ridgeline of the outer edge of the cutter wheel, the laser beam must penetrate the material or cut the material to form the microstructure, and the trajectory of the laser beam proposed by the patent CN200680003956.0 with respect to the disk surface of the cutter wheel is A closed or non-closed curve, the entire cutter wheel material contained in the curve must be cut off during laser processing to achieve separation from the original cutter wheel. This method does not remove a region of a certain depth from the material. In view of the above problems, the present invention provides a cutter wheel for cutting glass and other glass materials and a processing method thereof, and the cutter wheel of the new structure can prevent clogging, avoid collision of glass and avoid damage of 201121909.
