INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a tool structure, and more particularly to a structure of a cutting tool applicable to glass or wafer, which is provided by the present invention. The concave curvature of the cutting wheel cutter can actively improve the cutting quality and the service life of the cutting wheel cutter structure. [Prior Art] According to the glass and wafer produced by the general cerium oxide, the cutting operation is performed by a special tool. Since the production process of the wafer is expensive, it is necessary to avoid cutting due to cutting. Loss, so as not to cause an increase in production costs, and because of the rupture area of the surface of the wafer or glass caused by the cutting, is a major must-control factor, because the excessively large rupture area will cause the surrounding wafer or glass Unusable, resulting in losses due to cutting, and because the longitudinal cracking produced during cutting will also be related to the cutting tool. The cutting wheel cutter used in the prior art is applied to the cutting of glass or wafer, and the cutting of the glass mainly uses the cutting wheel cutter to cut the drawing line on the glass, and then breaks the glass along the cutting line. Related technologies for such glass cutting wheel cutters include Patent Publication No. 3 0 8 8 8 and the like. As shown in FIGS. 6 and 7, the cutting wheel cutter 90 of the prior art is a schematic diagram of a cutting wheel cutter 90 which is a disc body cutter including a shaft hole 9 1 and a front and rear circular ring. Faces 9 2, 9 3, the outer peripheral edges of the front and rear torus surfaces 9, 2, 9 3 are each tangentially formed at a 0-angle radial outward angle to form a cutting ring end 94 having a 2 Θ angle and the cutting The second end face 9 5, 9 6 of the ring end 9 4 is provided with a fixed pitch and alternating concave and convex portions 9 7 , 9 8 for use.
第5頁 1249460 五、發明說明（2) 利對玻璃進行切割。 前述該切割輪刀90之切割環端94具有較大的20角度及 相對組成該2Θ角度的二徑向平面切面，該較大角度雖可使 切割輪刀9 0之使用壽命變長，但卻會使切割時玻璃的水平 裂痕因材料於該平面切面推擠的問題而加大，進而導致切 割品質不良的缺失，而此缺失若出現於晶圓片的切割上， 則其所形成的後果損失顯然會更加嚴重，因此，該習知切 割輪刀技術顯非最佳之設計及較佳切割方式的解決手段， 而有待業界或有智之士再加以研發、突破之必要。 鑒於前述切割輪刀其切面角度所形成之使用壽命及切 割品質相衝突之缺點及其結構設計上未臻理想之事實，本 案發明人即著手研發其解決方案，希望能開發出一種兼具 較長使用壽命及較佳切割品質之切割輪刀結構以服務產業 及社會大眾，遂經多時之構思而有本發明之產生。 【發明内容】 本發明之目的在於提供一種切割輪刀結構，其係利用 一切割輪刀其係具有一内凹曲率，使該切割輪刀於其結構 設計上具有較長之使用壽命，且並能有效減緩切割時材料 所產生推擠之現象，進而獲得較佳的切割品質者。 本發明之再一目的在於提供一種切割輪刀結構，其係 利用一切割輪刀其係具有一内凹曲率，其能使切割時減低 橫向壓力而減少水平裂痕程度，進而兼顧其使用壽命及切 割品質者。Page 5 1249460 V. INSTRUCTIONS (2) The glass is cut. The cutting ring end 94 of the cutting wheel cutter 90 has a larger angle of 20 and a two-radial plane cut surface which constitutes the angle of the two, which can make the service life of the cutting wheel cutter 90 longer, but It will increase the horizontal crack of the glass during cutting due to the problem that the material is pushed on the plane cutting surface, which leads to the lack of cutting quality. If the defect occurs on the wafer cutting, the resulting damage will be lost. Obviously, it will be more serious. Therefore, the conventional cutting wheel cutter technology is not the best design and the solution to the better cutting method, and it is necessary for the industry or the intellectuals to further develop and break through. In view of the shortcomings of the service life of the cutting wheel cutter and the conflicting quality of the cutting quality and the fact that the structural design is not ideal, the inventor of the present case started to develop its solution, hoping to develop a longer one. The cutting wheel cutter structure with the service life and the better cutting quality is produced by the service industry and the public, and has been conceived for a long time. SUMMARY OF THE INVENTION An object of the present invention is to provide a cutting wheel cutter structure which utilizes a cutting wheel cutter having a concave curvature so that the cutting wheel cutter has a long service life in its structural design, and It can effectively slow down the phenomenon of pushing material during cutting, and thus obtain better cutting quality. A further object of the present invention is to provide a cutting wheel cutter structure which utilizes a cutting wheel cutter having a concave curvature which can reduce the lateral pressure during cutting and reduce the degree of horizontal cracking, thereby taking into account its service life and cutting.
