With the development of society and the progress of mankind, labor costs in European and American countries have been very high, and my country’s labor cost advantage is gradually losing. High efficiency has become the theme of the development of human society. Similarly, for diamond saw blade, users have increasingly pursued efficiency, that is, sharpness, which is their first goal. This is especially true for European and American users, and domestic users are gradually changing in this direction. The following introduces three methods to improve the sharpness of diamond saw blades-formula optimization, orderly arrangement of diamonds, and diamond brazing

1. Formula optimization

For the traditional diamond saw blade manufacturing process-powder and diamond are mixed and formed, then solid-phase sintered (sometimes with a small amount of liquid phase)-the choice of the formula of metal powder and diamond is the key to improving the sharpness of the saw blade. This process has no technical barriers, and high cost performance is very important. The company has conducted more research on the formulation of sharp diamond saw blades. The third part will introduce a cost-effective formulation of sharp dry-cut granite.

2. Orderly arrangement of diamonds

The orderly arrangement of diamonds is another effective way to improve the sharpness of the saw blade. Traditional diamond saw blades, the random distribution of diamonds in the matrix is prone to accumulation and segregation, which reduces the cutting speed. The diamonds are arranged in an orderly manner in the saw blade head, which can keep the diamonds in the blade head continuously sharpened and sharpened, and effectively improve the cutting performance of the saw blade. ·According to our company’s test and verification, under the same conditions (same matrix, same diamond grade and concentration), the cutting speed of orderly arranged diamond saw blades is more than 20% higher than that of conventional saw blades.

3. Brazed diamond saw blade

Brazing diamond tools refer to diamond abrasive tools made by brazing and connecting solders that can produce chemical reactions with diamond abrasives and produce metallurgical bonds with steel substrates. Due to its high diamond cutting edge, sharpness is its biggest advantage compared to sintered saw blades.

Brazing saw blades are also called fire emergency saw blades, which are mainly used in fire fighting, rescue, accident handling, etc., as well as occasions that require rapid treatment under special circumstances and environments. Unlike traditional diamond tools that only cut specific objects such as stone and concrete, fire emergency diamond tools need to have a broad spectrum of applications, not only to be able to cut stone and concrete, but also to have a wide range of cutting steel bars and various building materials. ability. The annual output value of domestic brazed diamond tools has exceeded 100 million yuan.
