Problems solved by technology

[0002] As we all know, in the field of cutting processing, diamond saw blades are generally used for cutting. The existing diamond saw blade materials are generally made of copper, iron, tin, nickel, cobalt and other metal components and diamond particles, and then add wetting The saw blade is formed by mixing and sintering after pressing and forming. Among the metal components used in the existing saw blade, the metal powder has a mesh number of 200-300 mesh. The existing material formula is unreasonable and the process It is also unreasonable, so that the sharpness of the formed product is not good, it is not easy to cut the workpiece, the cutting speed is very slow, resulting in very low work efficiency, in addition, its wear resistance can not reach the high Use requirements, short service life

Abstract

The invention discloses a diamond saw blade material and a manufacturing process. The diamond saw blade material comprises metal powders of 30-35 parts of copper, 40-45 parts of iron, 5-8 parts of tin, 3-5 parts of nickel, and 5-10 parts of cobalt, and the particle diameter of the metal powders is 1.5-2 [mu]m; and the volume ratio of diamond content to metal powder content is 12-18%. The diamond saw blade material and the manufacturing process have the advantage that due to the use of ultra-fine metal powders and the strict limitation of the component content of the metal powders and the ratiobetween the content of the metal powders and the diamond content, in addition, a reasonable process method is adopted, a formed product is quite sharp to achieve a very good cutting effect, the cutting speed is high, and the efficiency of use is improved; and moreover, the wear resistance also reaches an unprecedented height, and the service life is greatly prolonged.
