Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to a scribing tool using a diamond. [Prior Art] Previously, in order to cut the glass sheet, the cutting was performed by scribing and then breaking the glass sheet along the scribe line. The thickness of the glass plate to be used is various, for example, a relatively thick glass for building materials or automobiles, a large-area bonded glass plate for a large-sized LCD TV or the like, and a mobile phone, etc. Small glass sheets have a tendency to become thinner. When cutting a thin glass plate, in order to suppress irregular breakage, it is necessary to reduce the scoring load, and it is necessary to reduce the diameter of the scribing wheel. However, the smallest one of the scribing wheels is a scribing wheel having an outer diameter of about φ ΐ mm, so that there is a defect that it is difficult to further narrow. On the other hand, for the cutting of germanium semiconductors or sapphire, etc., a scribing tool using a diamond tip of a natural diamond (diam〇nd p〇int) is used. The above-mentioned tool using a diamond tip with a natural diamond can be expected to be non-f even if the diameter of the close circle can be reduced even when the thin glass plate is cut. Among the natural diamonds produced, the one with the highest frequency of occurrence, the octahedron crystal composed of 8 equilateral triangles as shown in Fig. 1(a), the second highest order of appearance frequency is as shown by _ 12 diamonds The dodecahedral crystals are assembled. In addition, there are regular hexahedral crystals having a lower frequency than the above-mentioned diamonds and composed of six regular squares (Fig. 1(c)). The surface of the hexahedral crystal is called a hexahedron or (10) plane. ^(4), a combination of a cube and a human face. 153879.doc 201201987 Natural diamonds of 1/70 to 1/80 carats have been used for the purpose of scribing glass plates. Patent Document 1 discloses a scribing tool that is joined to a base material such that three orthogonal axes correspond to a mounting shaft of one tool. After joining, the diamond is ground in the direction of the women's shaft to form a (1〇〇) plane, so that the point where the (1〇〇) plane intersects the octahedron (11) plane becomes a point of scoring. It is used for grinding. A tool used to intersect the four faces of the hexahedron ((100) face) and the octahedron (〇11) face is called a four-tip tool. The previous operation of joining the diamond that has been tested and ground (100) to the handle depends on the skill of the skilled operator. Therefore, in the scribing tool using natural diamonds, it is unavoidable that the inclination of the surface formed by grinding the diamond along the axial direction and the (100) plane is ～8 8 。. [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Patent Publication No. Sho 47-20236 SUMMARY OF INVENTION [Problems to be Solved by the Invention] The present invention has been developed in view of the above problems, and its technical object is The synthetic diamond can be held on the shank by reducing the inclination of the (100) plane and the surface formed by grinding the diamond along the axial direction, so that the manufacturing is easy and high performance is obtained. [Means for Solving the Problems] In order to solve the above problems, the diamond scribing tool of the present invention includes: the synthetic diamond abrasive grains '丨 including the first (100) plane and the second parallel to the first (1) plane ( 100) face 'the first 1 (1) (10) face and the adjacent at least two (1) face _.d〇c.4.

Here, the synthetic diamond abrasive grains may be set to have a weight of 1/1 inch or less. Here, the synthetic diamond abrasive grains may have four faces of the (111) face adjacent to the (1 〇〇) face, and four intersections thereof may be pointed. In order to solve the above problems, the diamond scribing tool of the present invention is formed by forming a pupil at the front end of the shank, and the second (100) plane including the iQOO) plane and the first (100) plane. The 丨 (1 〇〇) face of the synthetic diamond abrasive grain is temporarily fixed to a pressing jig including a surface perpendicular to the central axis of the shank, and the diamond abrasive grain of the pressing jig is applied to make the third 〇 (1〇) 〇) the surface and the shaft of the shank are pressed perpendicularly into the boring of the shank, and are welded by the welding material, and the synthetic diamond abrasive grains attached to the front end of the shank are ground and the first (100) plane At least two (111) faces are adjacent to each other, and their intersections are formed as pointed ends. Here, the polishing step may be performed by polishing four (111) planes adjacent to the first (1) plane, and forming four intersection points as sharp points. [Effects of the Invention] According to the present invention having the above characteristics, the crystal face can be easily found by using the synthetic diamond abrasive grains grown to the (1 〇〇) face, and is attached to the shank by using the face as a reference Therefore, it is possible to easily reduce the inclination of the diamond abrasive grains and easily manufacture the scribing tool. Moreover, by using a smaller diamond than the previous one, 153879.doc 201201987 diamonds can reduce the price of the scribing tool. Further, if the scribing tool is used, the scoring load can be reduced, so that it can be applied to the scribing of a thin brittle material (glass, enamel, sapphire, etc.). [Embodiment] In the present embodiment, the scribing tool developed by using the synthetic diamond developed as a wrong knife is used at the front end of the X tool to form a scribing tool. Here, the mine knife is used high. Oral synthetic diamond abrasive grains are described. High-quality diamond abrasive grains for saw blades are synthesized using seed crystals, and have a small inclusion size and a lb-type synthetic diamond of the same strength. For example, the particle size can be about or about 25 or so. Here, #16/2〇 is the same as the particle size which is classified by the sieve of the (6) sieve of the tiger and left in the sieve of No. 20. Synthetic diamonds for saw blades have higher fracture toughness values than synthetic diamonds for other applications (metal bonding or resin/clay, s), and the particle size is classified into the coarsest category as synthetic diamond abrasive grains. When the diamond abrasive grain is used as the scribing tool, the size of the size is not limited because only the corner of the diamond, that is, the tip, is used. Therefore, from the standpoint of cost, it is preferred to use a diamond that is smaller in the range that can be processed or joined. In the present embodiment, a high-quality diamond abrasive grain for a saw blade of about 1/17 inch carat, which is classified by a fine/25 sieve, is used as a synthetic diamond. It is also possible to use diamond abrasive grains of about 1/130 carat (about 15 mg) of saw blades of #18/20, preferably 1/100 carat or less. The (100) face of the synthetic diamond is formed substantially parallel to the opposite side of the diamond. Here, one of them is referred to as the first (100) plane, and the other is referred to as the second (100) plane. Also, attach the 1st (1〇〇) surface to the topless as the top.
