Symposium on the development of super-hard materials across the Taiwan Straits was successfully held in Jinghong City

[China Superhard Materials Network News] On the afternoon of April 23, 2014, the symposium on super-hard materials development across the Taiwan Strait was held in Jinghong City. More than 100 representatives of super-hard materials enterprises and industry experts from across the Taiwan Straits and across the country gathered together to discuss the problems faced by China's super-hard materials industry and the future development trend of the industry. The symposium was conducted in the form of a special report + on-site Q&A. It focused on the application of grinding technology for superhard materials in aerospace, the processing and application of superhard materials in the automotive field, and the status quo of Taiwan's diamond industry. And other industry related issues. The meeting pointed out a practical and feasible direction for the future development of China's superhard materials and products industry, and played an important role in promoting the sustainable and healthy development of the super-hard materials industry and promoting the exchange of super-hard materials industry across the Taiwan Straits.

Professor Fu Yucan of Nanjing University of Aeronautics and Astronautics pointed out in the special report on "Abrasive Processing Technology for Superhard Materials in Aerospace": "With the continuous improvement of the performance requirements of aerospace products for parts and components, traditional tools have encountered technical bottlenecks, especially In the grinding, the material removal rate is low, the grinding ratio is low, and the grinding life is low. The super-hard material tool is not suitable for processing, but it does not play a full role at this stage. If the super-hard material tool enterprise In order to better seize the market, we must find ways to provide users with a complete set of supporting solutions including machine tools, processing tools and processing technology."

Professor Fu Yucan also pointed out at the end of the report: "Because tool procurement has a small share in machining, most large aerospace companies are not sensitive to tool prices. They are more concerned with efficient machining efficiency and support. The processing technology solutions, so the best products and services are the most important, price competition is not wise. As long as the above technical problems are solved, super-hard tool companies will make a big difference in the field of machining."

Jiang Zhigang, Professor of Jilin University

Professor Jiang Zhigang of Jilin University said in the "Application of Superhard Materials in the Automotive Field": The rapid development of the automotive industry has driven the rapid development of the machine tool and tool industry. The global manufacturing industry's annual cutting and processing costs amount to more than 400 billion US dollars, of which the tool cost is about 20 billion US dollars. In recent years, the manufacturing industry in developed countries has adopted a large number of modern and efficient cutting tools to increase labor productivity. The annual cost savings for the manufacturing industry is 100 billion US dollars, far higher than the investment in tools. ”

Global cutting tools are distributed according to the sales of the production sector. General machinery accounts for 35%, automobiles account for 34%, aviation industry accounts for 12%, medical machinery accounts for 5%, molds account for 4%, and other 10%. The total number of components in the automotive sector is basically around 30,000, and more than 800 parts need to be machined, including: engines, gearboxes, axles (ground), steering gears and various pumps. At present, the tooling structure of the automotive industry, in which the market capacity of cemented carbide coated tools and ceramic tools has increased significantly, still holds the largest share of the tool market, but superhard tools are mostly used for high-efficiency, high-precision machining, and the market share is growing rapidly.

At present, the product structure of superhard tools in the domestic automotive industry is still in the low-end, and the price competition is more serious. However, domestic competitiveness is seriously lacking in high-end products, and the main products are still mainly imported. In the future, China's super-hard materials companies should take high-end products as a very important task, and it is imperative. The state and associations should also focus on supporting a number of advantageous enterprises and create a number of advantageous brands with strong market competitiveness.

Chen Zongqi, R&D Manager, Taiwan Diamond Industry Co., Ltd.

Mr. Chen Zongqi gave a detailed introduction to the development status of Taiwan's diamond tool market and the processing and application of Taiwan's diamond tool products in the semiconductor industry, silicon wafers, sapphire cutting, and liquid crystal glass panels. The report also said: "Taiwan's diamond tool market is much smaller than the mainland market. The annual market size is about 80-8.5 billion US dollars. In 2013, Taiwan's total imported diamonds were 74055,000 carats and CBN was 280 million carats. 70 of them. % used in the semiconductor industry, 14.5% in the machinery industry, and the rest in transportation, construction and other industries. Taiwan has more than 80 diamond tool manufacturing and sales companies, Taiwan Diamond Industry Co., Ltd. occupies 25% market share."

Wang Xin, deputy secretary of the party committee of Fuyang City

At the end of the meeting, Wang Xinzuo, deputy secretary of the Party Committee of Xiangyang City, made a special report on “Patent Leading Innovation and Development”. The report pointed out that Fuyang New Material Industrial Park is the first batch of “National Patent Navigation Industry Development Experimental Zone”. It is a concrete practice of implementing IP strategy to promote innovation-driven development strategy at the national level. It is based on patent information resource utilization and patent analysis. Foundation, embedding patent application into industrial technology innovation, product innovation, organizational innovation and business model innovation, guiding and supporting an exploratory work of industrial science development. The construction of the patent navigation experimental zone will be beneficial to give play to the guiding power of patent resources to the decision-making of superhard materials industry operation, the allocation of industrial innovation resources, the control of industrial competition market and the support of industrial operation efficiency. Fuyang New Materials Industrial Park will continue to make efforts in the areas of “reducing the comprehensive operation cost of enterprises and improving the competitiveness of enterprises in science and technology”.
