[14] The present invention is mounted on a cutting tool such as a sawing machine, a grinding wheel machine, or a core drilling machine for cutting and polishing a stone such as granite, marble, concrete, and a difficult cutting material such as metal or ceramic. In particular, the present invention relates to a diamond cutting wheel for use in the present invention. In particular, a diamond cutting wheel is formed at a predetermined interval around an outer circumferential surface of a rotating body and is formed by sintering and attaching a diamond tip and protruding to one side of the rotating body. Holes are formed in the upper horizontal portion, and a reinforcing tip and a hole are radially arranged on the inner surface of the lower horizontal portion which is integrally formed with the upper horizontal portion in the direction in which the rotor is rotated so as to rotate. The cutting wheel is deformed by allowing dust or residue and frictional heat generated during cutting or grinding to flow to the outside through the through hole. It relates to a diamond cutting wheel so.
[15] In general, diamond has high hardness and thermal conductivity, so it shows excellent performance as cutting tools and wear-resistant tools, and is used for various purposes. Especially, non-ferrous metals such as Al-Si alloys and CUs, which are difficult to machine, and composite materials And semi-sintered bodies such as graphite, polymer composite materials, and ceramics. In the processing of such hardened materials and various stone and metal materials described above, many diamonds having the highest hardness value are used. Its use is also essential.
[16] By using diamond properties, diamond powder is coated on the surface of the tool for grinding, cutting, etc. of stones, hard materials, and metals, or it is in the range of about 0.2 to several hundred μm through vacuum coating method. In addition, a diamond tip is used in which diamond crystal particles are coated on the surface to be bonded of a tool such that the roughness Ra value is in the range of approximately 0.1 to 100 µm.
[17] In order to form the diamond tip as described above, a sintered diamond tool is formed by using a vapor deposition method on a base material or by depositing a diamond film on a base material processed into a certain shape to have a complete diamond structure. In view of the above abrasion resistance and the reduction of manufacturing cost, the research is being conducted in various angles. Also, various vapor deposition methods such as chemical vapor deposition (CVD) are coated. As such, the details regarding the manufacture of the diamond tip are excluded from the scope of the present patent, and thus detailed description thereof will be omitted.

[19] The diamond cutting wheel 100 is coupled to the cutting tool (stone, metal, ceramic, etc., such as granite, marble, and concrete), and the like, referred to as "work material", and the work is cut and polished.
[20] Thus, when cutting and polishing the irregular workpiece surface with the diamond cutting wheel 100, (dust or residue) of the workpiece shall be referred to as the "workpiece" and the workpiece is rotated with the inner surface of the rotating body space to reduce friction. When the damage caused by scratches or any external force caused by the inner surface of the rotor 100 due to the irregular thickness there is a problem that the cutting wheel is bent or twisted due to severe shaking phenomenon and frictional heat during high-speed rotation
[21] In addition, when the diamond cutting wheel 100 is bent or twisted continuously to perform cutting and polishing operations, the diamond cutting wheel 100 is damaged by cracks, and the life of the product is shortened, and the broken cutting wheel There is a serious problem that industrial accidents are caused by the fragments of workers, which greatly impairs the safety of workers.
[22] In order to solve the above problems, the present invention is a workpiece generated during the cutting process by drilling a through hole in the upper horizontal portion of the circular protruding to one side of the diamond cutting wheel and the lower horizontal portion extending to the upper horizontal portion To minimize the wear on the inner surface of the rotating body and to maximize the cooling effect of the frictional heat by allowing the air to flow, and to form radial reinforcement tips on the outer circumferential surface of the rotating body. The purpose is to improve the safety of the product according to the safety of the work, extending the service life by improving the durability.
