The Development of Diamond Tool Matrix

2023-04-28

Nowadays the development of diamond tool matrix technology can be divided into three stages:

The first stage is to make diamond tools with monolithic powder as matrix plus diamond with mechanical mixing process. This process is easy to produce composition segregation; The high sintering temperature is easy to cause diamond graphitization and reduce the strength of diamond. Since the various casing materials are mechanically combined and not fully alloyed, the effect of matrix on diamond encrustation is poor and it is difficult to produce high-grade products.

The second stage is to use pre-alloyed powder as the matrix plus diamond mixing process to make diamond tools. Due to the full alloying of the body material and the low sintering temperature, the process will not reduce the strength of diamond, avoid the segregation of the composition and producing good encrustation effect on diamond, which makes the diamond function well. The diamond tooling produced by using pre-alloyed powder as the matrix have the characteristics of high efficiency and slow decay, which can produce high quality diamond tools.

The third stage is the use of pre-alloyed powder as the matrix and the adoption of ordered arrangement technology for diamonds. This technology accommodates the technical advantages of pre-alloyed powder and arranges the diamonds in an orderly manner so that each grain of diamond is fully utilized, overcoming the defect of uneven distribution of diamonds that seriously affects the cutting performance brought by using mechanical mixing process, which is the latest technology for producing diamond tools in the world today.

With the expansion and change of diamond grinding tool application fields and the improvement of tool performance requirements, the use of ultra-fine pre-alloyed powder as the matrix gradually evolves into the main way to improve the quality of the tool industry in the future, supplemented by the improvement of other process equipment, thus promoting a new change of diamond tool product quality.
