Description

200538260 V. Description of the invention ο [Technical field to which the invention belongs] The present invention relates to a tool structure, in particular, a structure of a cutting tool that can be applied to glass and wafers. The cutting provided by the present invention The concave curvature of the wheel blade can actively improve its cutting quality and service life of the cutting wheel blade structure. [Previous technology] According to the general, the cutting operation of glass and wafers produced by stone dioxide is performed by special tools. Because the wafer production process is expensive, it must be avoided as much as possible when cutting. The loss caused to avoid increasing the production cost, and the cracked area of the surface of the wafer or glass caused by cutting is a major factor that must be controlled, because an excessively large cracked area will cause the surrounding wafers or Glass cannot be used, resulting in losses due to cutting, and because of the longitudinal cracks generated during cutting, it is also related to the cutting tool. A cutting wheel knife that is commonly used is used for cutting glass and even wafers. The cutting of glass is mainly using a cutting wheel knife to cut lines on the glass, and then break the glass along the cutting line. Related technologies of such glass cutting wheel blades include Patent Bulletin No. 3 0 8 5 8 1 and the like. As shown in FIGS. 6 and 7, it is a schematic diagram of a cutting wheel blade 90 of the conventional technology. The cutting wheel blade 90 is a disc-shaped cutting tool, which includes a shaft hole 91 and front and rear circular rings. Faces 9 2, 9 3, and the outer and peripheral edges of the front and rear annular faces 9 2, 9 3 are tangentially angled outward at a radial angle of 0 to form a 20-degree cutting ring end 94 and the cutting The ring end 9 4 has two front and rear cutting planes 9 5 and 9 6. The cutting ring end 9 4 is provided with concave and convex portions 9 7 and 9 8 of a fixed pitch and alternating with each other.

Page 5 200538260 V. Description of the invention (2) It is beneficial to cut glass. The aforementioned cutting ring end 9 4 of the cutting wheel blade 90 has a larger 20 angle and two radial plane cutting planes which relatively constitute the 20 angle. Although the larger angle can make the life of the cutting wheel blade 90 longer, However, the horizontal crack of the glass during dicing will be enlarged due to the problem of the material pushing on the plane cut surface, which will lead to the lack of poor cutting quality. If this defect appears on the wafer cutting, it will be formed. Consequential losses will obviously be more serious. Therefore, the conventional cutting wheel technology is obviously not the best design and a better cutting method. It needs to be researched and breakthrough by the industry or a person with wisdom.鐾 Because of the disadvantages of the conflicting service life and cutting quality formed by the cutting surface angle of the aforementioned cutting wheel blade and the fact that its structural design is not ideal, the inventor of this case set out to develop its solution, hoping to develop a solution The cutting wheel blade structure with long service life and better cutting quality serves the industry and the public, and the invention came into being after many years of conception. [Summary of the Invention] The object of the present invention is to provide a cutting wheel cutter structure, which uses a cutting wheel cutter which has a concave curvature, so that the cutting wheel cutter has a long service life in its structural design, and Can effectively slow down the phenomenon of material pushing during cutting, and then obtain better cutting quality. Another object of the present invention is to provide a cutting wheel blade structure, which utilizes a cutting wheel blade which has a concave curvature, which can reduce the lateral pressure during cutting and reduce the level of horizontal cracks, thereby taking into account its service life and cutting Quality person.

Page 6 200538260 V. Description of the invention (3) In order to achieve the above-mentioned object and effect, the technical means adopted by the present invention includes a cutting wheel cutter, which is a disc cutter having a thickness, which includes: The front and back circular toroids, the outer peripheral edge of the torus is outwardly connected with a concave concave surface, the concave concave mask has a radius of curvature R, and the radius of curvature R is between 2 ~ 2 0 0 mm In the meantime, the inner concave cutting surface connecting the outer peripheral edges of the annular surface and intersect to form a cutting ring end, and the cutting ring can be used to perform cutting operations on glass, wafers and the like. [Embodiment] In order for your review members to have a better understanding and understanding of the structural features and achieved effects of the present invention, I would like to provide a better embodiment and a detailed description, as described below: The present invention is to solve The cutting surface of the cutting tool of the conventional technology is caused by the vertical and horizontal damage surface, because the larger the angle of the cutting tool, the longer the life of the cutting tool, but the horizontal crack during cutting will be caused by the problem of material pushing. It increases the cost pressure caused by cutting. Therefore, the present invention provides a cutting tool with concave curvature, which reduces the phenomenon of cutting material pushing. The lateral pressure is smaller than a cutting wheel with the same angle. It can reduce the level of horizontal cracks, and then obtain better cutting quality. First, referring to FIG. 1 to FIG. 2, the cutting wheel structure of the present invention includes a cutting wheel blade 10, which is a disk cutter having a thickness T, which includes a shaft hole 1 2 And front and back circular toroids 1 4 and 1 6, the shaft hole 12 is used for penetrating a cutter spindle (not shown), and the cutter spindle can also be connected with the cutting wheel cutter 1 0—body forming, and the front and back torus 1 4,

The system has an inner surface ... 20 'rate radius R is between 2 ~ 200mm, f abundance diameter R, and the concave curve intersects to form a cutting ring end 2 Cutting planes 1 and 20 are used for cutting operations such as E-pieces. Borrow " " Haiche σ 彳 ring end 2 2 can be used for glass, crystal garden, please refer to Figure 3, too, because the concave cut surface X is cut by the cutting ring end 22 when cutting material. Recessed, 20 has a concave arc slope, which can cut

The lateral pressure is relatively the same and the pushing phenomenon of 8 and 20 is slowed down, which makes the j2 less cutting. The flat cutting plane is smaller, which can be better and more accurate. The degree of expansion of the horizontal crack is more precise. , And / or cutting & knife with the same angle.
