Today, I am very pleased to gather with friends from the diamond industry all over the world in Zhengzhou, a famous city in the Central Plains. I will hold the 6th Zhengzhou International Superhard Materials and Products Seminar to celebrate the 50th anniversary of the birth of artificial diamonds. I represent the China Machine Tool Industry Association. Friends from all over the world expressed their warm welcome and expressed their heartfelt congratulations on the convening of the conference!
Fifty years ago, under the cordial care of the party and state leaders, and with the support of relevant state ministries, Chinese scientists have overcome their difficulties with their own wisdom under extremely simple conditions, and have developed a complete set of independent knowledge. The unique and artificial synthetic diamond manufacturing equipment and technology made the birth of synthetic diamonds in China. Three years later, cubic boron nitride was successfully developed, which is a major scientific achievement in the history of China's scientific and technological development. Since then, the glorious chapter of the rapid development of China's superhard materials has been opened. After 50 years of development, China's superhard materials industry has formed a complete and huge industrial system including synthetic diamond, cubic boron nitride and various tool products. Superhard material single crystals and some superhard materials have reached the world's advanced level. The rapid development of the industry has not only revolutionized the traditional processing technology, but also promoted the industry and strategy of stone, building materials, machinery, electronics and military industries. The rapid rise and vigorous development of new industries has made due contributions to the development of the entire national economy, and has also made due contributions to the world's superhard materials industry.
In the past 50 years, China's super-hard materials industry has gone through a glorious history from scratch and from small to large. Some products such as grinding single crystals have completed the development process from weak to strong, and now they are moving towards weaker. Going forward in a strong direction. History has proven that the road to manufacturing super-hard materials with a unique six-face press with complete intellectual property rights is in line with China's national conditions; thus, China's super-hard materials industry has developed rapidly. China's diamond production has accounted for more than 90% of the world's total output, and cubic boron nitride products have accounted for more than 60% of the world's total output. More and more customers from various countries have adopted a variety of Chinese superhard abrasive products. World-famous companies have also procured China's unique six-face press and borrowed Chinese craftsmanship to manufacture diamonds and related products, which is rare in China's manufacturing industry.
The development of China's superhard materials industry has the influence of advanced technology in developed countries. It has the guiding role of seminars held by industry associations. It is supported by government agencies at all levels in China, and has the unremitting efforts of industry scientists, engineers and workers. The great achievements not only benefit China's manufacturing industry, but also benefit users from all over the world. Today, friends from all over the world gather here to discuss industry technology and future development. This is a rare opportunity. I sincerely hope that you will make full use of this opportunity to extensively exchange and cooperate in technology, products, trade, information and other aspects, and learn from each other's strengths and make progress together. Grasping the State Council's major opportunity to include superhard materials in the strategic 12th Five-Year Plan for emerging industries, and to be a pioneer in China's economic upgrading and transformation, and to make greater contributions to the low carbonization and prosperity of China and the world economy.
I wish the conference a complete success! I wish you all good health, good work and good luck!
Thank you!
