|Title||The status quo of Chinese abrasives in the world|
The world's superhard material tools are produced all over the world. Among them, 12 inches cut off wheel tools are manufactured in Japan, Germany, the United States and South Korea. These countries are rapidly turning tools for superhard materials. Other abrasives have been used. It is decreasing year by year. Because of its high efficiency, energy saving, long life and environmental friendliness, super-hard materials have ten times higher efficiency and life than traditional tools.
China's superhard materials industry began in the 1970s. Prior to this, almost all of the super-hard material tools such as diamond saw blades were imported. In the 1980s, a large number of production enterprises mainly producing small-diameter diamond saw blades were launched, and the high-speed development period began in the 1990s. The super-hard material tool industry has realized a complete industrial system with complete scale and considerable scale, from the end to the present, including the supporting raw material supply system, equipment supply system, auxiliary material system and market system. Produce tools for superhard materials that basically meet the needs of the development of various industries. There are still a large number of products exported every year, especially in the middle and low-end products, but at the high-end product manufacturing and technical level, compared with the advanced level of foreign countries. There is a certain gap.
With the continuous advancement of science and technology, the unique properties of super-hard materials have been continuously developed and utilized. The technical level of super-hard materials has been continuously improved, and the application fields have been continuously expanded. The super-hard material products industry has become an indispensable important part of national economy and national defense construction. component. With the maturity of synthetic diamond technology and the rapid development of China's economy, diamond tool manufacturing technology has accumulated and progressed, and has strong manufacturing capabilities.
Due to the advantages of enterprises in labor costs and the subsequent catch-up situation in technology research and development, Chinese enterprises have obvious advantages in product cost performance. With the rapid growth of market demand, diamond tool companies all over the world have launched, and a number of advantageous enterprises with international competitive strength have emerged. China has become an important producer, user and exporter of diamond tools in the world, with an annual output value exceeding 10 billion yuan. The application of diamond tools in emerging industries is expected to expand further with the increasing grade of synthetic diamonds. Its excellent performance is expected to be widely used in high-tech fields, such as machining of precision instruments such as aerospace instrument bearings, radar waveguides, optical devices, high-energy smokers, etc.; can be used for single crystal silicon, polycrystalline silicon 0.1-0.2mm High-precision precision machining such as cutting, grinding, and satellite solar panels for thickness sheets; it can be used for micro-precision cutting, slotting, back-thinning, and nano-diamond polishing of large-scale integrated circuits such as computer chips. The developed countries in the world all regard superhard materials and products including synthetic diamonds as the development focus. The research and application level of superhard materials and their products represent the level of scientific and technological development of a country to some extent.
