Diamond tool

This creation is about a diamond tool, especially a diamond tool made of a tool body combined with a reinforced resin layer.

Please refer to FIG. 17 , which is a schematic view of a diamond saw blade made of a diamond mechanical press. The general diamond saw blade is mechanically pressed by a circular copper plate or a soft metal plate to form diamond particles and a circle. The outer edge of the copper plate body is combined to form a diamond saw blade 80a. However, the diamond saw blade 80a is made of copper or a soft metal plate. The strength of the copper material can only be cut slowly, and it is easily deformed and damaged when used at high speed cutting. FIG. 18 is a schematic view showing the structure of a diamond saw blade made of a conventional metal sintered type, which is a diamond metal sintered diamond saw blade 80, which is mixed with various metal powders and diamond particles, and placed in a special The mold is formed into a powder block by cold pressing, so as to strengthen it, it is necessary to form a diamond grinding wheel block 801 containing diamond material strengthened by a high temperature of 850 ° C, and then welding each diamond grinding wheel block 801 to a circular shape with a shaft hole. A diamond saw blade 80 is formed at the outer edge of the steel sheet 820. However, the above-mentioned diamond metal sintered diamond saw blade 80 can be produced by using high-cost diamond particles and various metal powders, and when the diamond particles are mixed with the metal powder, It is easy to cause skin lesions in the staff, and the peripheral equipment system is extremely expensive, and it consumes electric energy and forms air pollution. The production process is cumbersome, and the cost is extremely high. The unit price of the finished product is not more mechanical. The number of copper diamond saw blades 80a made is many times, which is difficult to meet the cost reduction requirements of various industries. Furthermore, the diamond saw blade 80a which is pressed by the diamond mechanically has a slightly smaller cutting effect than the diamond saw blade 80 made of metal sintered. It can be seen that the advantage of the mechanically stamped (Fig. 17) diamond saw blade 80a is that the manufacturing cost is low and the production is simple, but the strength is insufficient; and the diamond metal sintered diamond saw blade 80 is mainly made of steel. Therefore, the strength is good and the deformation is good, and the cutting function is good, but the manufacturing cost is extremely high. In view of the lack of improvement in the above two production methods, the creator has been thinking about how to reduce costs, simplify the production process and enhance the sharpness of the diamond saw blade based on years of experience in the industry, and maintain the advantages of the two finished products.

Referring to FIG. 19 and FIG. 20, it is a simple schematic diagram of a cross section of a sharp-edged blunt diamond particle at the leading edge of a polished diamond saw blade and a complete exhausted diamond particle at the leading edge. The electroplated diamond saw blade is mainly used as a cutting edge portion 901 (Fig. 19) at a suitable position of a shank or blank of a single body, and is formed outside the cutting edge portion 901 by metal plating. The diamond particles 902 are solidified to form an Electroplated Diamond Blade, or the diamond particles 902 are fixed by metal welding to form a Metal Bond Single layer Diamond Blade. At the time of cutting, the diamond particles 902 which are solidified by the cutting edge portion 901 of the diamond cutting edge are used for cutting the article. When the sharp angle of the diamond particles 902 fixed by the leading edge of the cutting edge portion 901 is blunt, the cutting ability is Will be under rapid The drop directly affects the work efficiency, especially when the diamond particles 902 fixed by the leading edge of the cutting edge portion 901 are completely worn or completely detached, that is, the metal leading edge of the cutting edge portion 901 and the cut object are slippery, and the cutting edge can hardly be cut. The use, especially the greater the thickness of the cutting edge portion 901, is more serious. It can be seen that the service life of the foregoing structure is extremely limited, as long as the single-layer diamond particles 902 which are solidified at the leading edge of the cutting edge portion 901 are blunt or completely worn, that is, the cutting work cannot be performed at all. Because the metal thickness of the cutting edge portion 901 is higher and exceeds the thickness of the diamond particles 902 layered on both sides thereof, the metal edge of the cutting edge portion 901 (the diamond particles have been worn out) can only be cut. The surface of the object is slippery and cannot be cut in depth. The 902 layers of diamond particles on both sides of the object are also free of auxiliary cutters.

Therefore, the four types of diamond saw blades described above have their own advantages and disadvantages and existing problems, so how to extract the advantages of each part, so as to develop the high-speed cutting is not easy to deform, the cutting effect is good Diamond saw blades with long cutting life and low cost are the problems that creators want to solve.
