World champion, strive to reach the world's advanced level by 2020! To achieve this goal, it is a long way to go, full of challenges, full of hope!

        The development of diamond single crystal: As far as abrasive grade diamonds are concerned, it can be said that China Diamond has completed three major developments from scratch, from small to large and from weak to strong, and has reached the goal of a world power. At least we can get it. This single world champion. In 1963, China's diamond research and development was successful, achieving a breakthrough in China's diamonds! In 1966, it entered the pilot stage, and in 1971, it entered the small-scale production stage. In 1984, the diamond production technology was promoted and applied in some enterprises. In 1992, the diamond production technology was widely promoted nationwide and triggered the rapid development in the future. China's annual diamond output exceeded 1 billion carats, and in 2012 it reached a historical high of 14 billion carats.

        Development of nano-diamonds, cubic boron nitride single crystals, and composite super-hard materials: In 1971, China first synthesized nano-diamonds by explosive method. In 1975, nano-cubic boron nitride was synthesized by explosion method. In 2001, China built an annual output of 1000-2000. 10,000 carat nano diamond production line. At present, there are more than ten specialized production enterprises in China, which use the explosion and detonation methods to produce polycrystalline and single crystal nano-diamonds with an annual production capacity of 100 million carats. Although the development of cubic boron nitride in China is relatively slow, it has reached an all-time high of 380 million carats in 2012. Following 1969, China developed a diamond composite PCD with nickel and silicon as a binder. In 1973, it successfully developed PCBN. In 1975, it successfully developed a tool diamond composite PDC. In 1987, it developed a diamond composite PDC for drilling. Started small-scale production; industrial production began in 1992; in 1996, diamond composite PDC with cobalt as binder was successfully developed. At this point, the complete series of PCD, PDC, PCBN composite superhard materials for various purposes have formed industrial production and rank among the world's advanced levels.

        The development of super-hard abrasive products : all kinds of super-hard abrasive products develop rapidly, a wide variety of doors, a wide range of applications, production companies all over the country, especially for grinding and cutting tools in the field of mechanical electronics, for stone and floor tiles, etc. Sawing tools for building materials, tools for geological exploration and mineral mining, and engineering drilling have been rapidly developed.

        The development of the six-face press: In 1965, the 6*6MN six-face press was successfully trial-produced, and the first diamond production in China began. In the next 20 years, the press dominated the world.
In 1984, 6*8MN and 6*10MN six-sided top presses were successfully developed. From 1998 to 2006, the design and manufacture of the six-face press was active and the hands were relatively active. Dozens of industrial press production plants and large diamond production plants set off a competition to continuously expand the tonnage of presses. The continuous large-scale operation of the press provides equipment guarantee for the synthesis of high-grade diamonds. The continuous improvement of the level of press and diamond synthesis has greatly improved the international image of China's diamond industry, and internationally renowned companies have purchased a large number of Chinese six-face presses. The Chinese method of producing diamonds is rare in today's Chinese manufacturing industry. At present, the international market is getting bigger and bigger, and the export situation is getting better and better. In 2000, China's diamond products exports increased from 115 million carats to 2.13 billion carats, with an average annual compound growth rate of 27.6%. The number of destination countries has grown from 30 to 58 and has nearly doubled. The overall development trend is very rapid.

Major problems and shortcomings in the development of industrial products

      There are few high-end products, and the structural contradictions of medium and low-end products are still outstanding: China's diamond exports are mostly in the middle and low-end products, and the proportion of high-end products is very low. Domestic high-end users have to import at high prices.

        The independent innovation capability of enterprises still needs to be greatly improved: in the super-hard materials industry, the leading companies of various products that focus on independent innovation can develop and produce some international high-end products, but the output is not large enough to meet the domestic and international market demand. The number of these enterprises is small and it is difficult to represent the overall level of the industry.

        The conditions for ensuring the stability of product quality are still insufficient, the specialization of production and the degree of product specialization still need to be further improved: although the degree of specialization of products in China has increased in recent years, there is still much work to be done, and a lot of work is required to inject diamond single crystals. A special product of the kind. Further improving the degree of product specialization is a major task before us, and it is also the only way for the industry to transform and upgrade its products.

        The market competition order still needs to be further regulated: Although the competition order has improved in recent years, the shadow of vicious competition with price cuts still exists and needs to be further regulated.

        Further carry out joint restructuring or mergers and acquisitions to expand the scale, improve the competitiveness of enterprises; further improve product quality standards; continue to strengthen the research of cutting-edge technology and non-grinding applications of super-hard materials.

a bright future full of hope

        China's macro economy will continue to be a super-hard engine for superhard materials and the entire manufacturing industry. In the 30 years from 1982 to 2012, China's GDP grew at a compound annual growth rate of 16.5%, and the speed of development is surprising. Looking at the international and domestic trends, China's development is still in an important strategic opportunity period that can make a big difference. With the strong promotion of the national policy, the strong pull of the huge market, the rich development experience of the 30 years of reform and opening up, and the strong momentum of vigorous growth, China's macro economy will continue to improve in the next few decades, and the manufacturing industry will continue to improve. This will promote the continuous improvement of the superhard materials industry.

        The development history of building materials and materials is a powerful engine for the development of diamond sawing and polishing tools. Real estate is the engine that drives economic development. It is also the engine that drives the development of the diamond industry. Buildings need diamond tools to drill walls and floors to process various pipelines. The future development trend has a major impact on the development of the diamond industry.

        The development of machining is a powerful driving force for the development of precision grinding tools for superhard materials. Machine tools, automobiles, tractors, home appliances, aerospace, military, etc. are the main application fields of precision grinding and cutting tools for superhard materials. Electronic fields such as integrated circuits and mobile phones, clean energy, photovoltaics, etc. are new application fields, and The development potential is huge.

        The exploration and development of mineral resources such as oil and natural gas and large-scale subway construction are powerful driving forces for the development of diamond drilling and mining tools. With the rapid growth of global oil and gas consumption and demand, the exploration and development of oil and gas resources is not only related to the development of the national economy, but also related to the country's energy security. The rapid development of oil and gas exploration and development, coupled with the exploration and development of mineral resources such as coal, steel, non-ferrous metals and non-metals, and the large-scale construction of subways in China, all provide attractive and broad development prospects for diamond exploration and mining tools.

        Industry development has a long way to go and is full of hope. China's super-hard materials industry has experienced a century of glory, and has gone through 50 years of glory! It has achieved great achievements that have attracted worldwide attention. The production of superhard material single crystal has been ranked first in the world for more than 10 years, and its quality has reached the world advanced level. It can be said that we have won the single champion of super hard single crystal production in the world; The quality of super-hard materials has reached the world's advanced level. However, we still have many difficulties and problems that need to be overcome. The gap between high-end products and developed countries is still very large. The industry continues to develop healthily and still has a long way to go!

        The development of China's future superhard materials industry has a long way to go, full of challenges and full of hope!

        We are willing to join hands with the world's superhard materials to learn from each other's strengths, make progress together, continuously expand the application of new fields, and provide more efficient, precise and environmentally-friendly super-hard materials for the development of a low-carbon and environmentally-friendly world economy, for the development of human civilization.
