The Chinese diamond tool industry in my eyes

Diamond tool is the ideal tool for high hardness materials. It has good processing quality and high efficiency. It can greatly reduce processing costs, improve working conditions, and facilitate the implementation of mechanized and automated processing. As early as 50 years ago, people are struggling to find ways to change. Hard and brittle processing industry is a difficult and inefficient labor state. China's diamond industry started relatively late. As early as the 1960s, China successfully developed artificial diamonds. However, until the 1980s, diamond tools such as grinding, cutting, and drilling began to develop and became industrialized. In the late 1980s, with the rise of China's manufacturing industry in the world, China's diamond tool manufacturing industry has also shown a strong vitality and rapid development, and it has now become one of the major suppliers of diamond tools in the world.

There are more than 1,000 diamond and diamond tool manufacturers. In 1999, the annual output of diamonds exceeded 750 million carats, becoming a major diamond producer. Diamond saw blades have been able to meet domestic demand. Nearly 1/3 of the products are exported, forming a certain level of competitiveness in the DIY market.

We will vigorously develop the hardware tool industry, pay close attention to the development of new products and new technologies, accelerate the development of the hardware tool industry in China, and increase economic efficiency and overall technological level. Only on the issue of improving the quality of diamond tools in China, put forward some views. The specific approach is:

1, the tool industry investment, pay close attention to the development of new products and the promotion of new technologies, new processes, continue to broaden the field of diamond applications, for the production of diamond tools to provide stable production of large-scale performance, coarse particles, high thermal stability of the diamond, To improve the overall technological level and market competitiveness of the diamond tool industry, strive for survival with variety and quality, and seek development with scientific and technological progress.

2, must accelerate the development of new products, improve product quality, increase variety, increase production. Use strong carbides to form elements and increase diamond holding power. In order to ensure the quality of its products, we must speed up the promotion of new technologies and new processes, such as vacuum welding technology, electric spark sintering technology, diamond uniform technology, diamond rhodium plating technology and metallization bonding technology, laser welding technology.

3, take the road of high quality and efficiency, energy conservation and emission reduction.

4. Improve the overall technical level of the diamond tool industry and promote the granulation process in the production of cutter heads. In the sintering process, vacuum protective atmosphere hot press sintering process and equipment are promoted. In the production of diamond wire saws, hot isostatic pressing and high-temperature brazing are used to actively develop high-grade laser welding saw blades.

5. Rational division of labor, organization of large-scale production, and improvement of international competitiveness The overall level of development of an industry depends, in the final analysis, on the level of business and the speed of development of the industry. In order to achieve a successful transition from big to strong, the diamond tool industry in China needs independent self-reliance and self-improvement so as to promote the development of the entire industry.
