Problems solved by technology

Although the cutting efficiency of the combination saw is high, its requirements for the sharpness of the single saw blade are relatively low.
[0003] Diamond saw blades have the advantages of high hardness and good wear resistance. At present, the main problem of diamond saw blades is that the blade head is gradually worn during the cutting process, resulting in a decrease in the sharpness of the blade head. The heat can cause the diamond to heat up too quickly and cause damage
[0004] The wear resistance of the diamond saw blade also has a great influence on the cutting efficiency. If the wear resistance of the metal alloy is too high, it is easy to cause the diamond blade to be too slow to affect the height of the blade. If the wear resistance of the metal alloy is poor, it is easy to damage the saw during the cutting process. substrate damage
At the same time, debris is generated during the cutting process, which is easy to cause wear on the surface of the saw blade and affect the service life of the blade

Abstract

The invention relates to a diamond saw blade tip, a diamond saw blade and a manufacturing method thereof, and belongs to the technical field of diamond tools. The diamond saw blade tip is formed by a front section material, a middle section material and a rear section material. The front section material and the rear section material each comprise, by mass, 20%-22% of diamond particles, 18%-22% of copper powder, 15%-18% of cobalt powder, 20%-30% of tungsten powder, 2%-5% of silver powder and 12%-15% of tin powder, wherein the sum of all the components is 100%. The middle section material comprises, by mass, 15%-18% of diamond particles, 18%-22% of copper powder, 17%-20% of cobalt powder, 22%-32% of tungsten powder, 3%-5% of silver powder and 13%-15% of tin powder, wherein the sum of all the components is 100%. The diamond saw blade tip has excellent sharpness and abrasion resistance, and the cutting efficiency and service life of the diamond saw blade are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of diamond tools, and in particular relates to a diamond saw blade head, a diamond saw blade and a manufacturing method thereof. Background technique [0002] The diamond saw blade is composed of a disc-shaped substrate and a diamond head connected to the outer edge of the substrate. It has been widely used in the cutting of non-metallic materials. It is mainly suitable for trimming and cutting in glass and ceramics. Because glass is easy to Fragility, so the saw blade is required to be thin; and the ceramic hardness is high, so the saw blade is required to have good cutting performance; in the field of stone processing, diamond saw blades are widely used, generally there are single-chip diamond saws and combined diamond saws, Although the efficiency of the single-chip saw is lower than that of the combination saw, it is also widely used, especially when cutting edges, it is faster to use the single-chip saw...
