On May 16, 2018, the 5th Executive Director (Extended) Conference of the Superhard Materials Branch of China Machine Tool Industry Association was held in Guangzhou Yueda Financial City International Hotel. More than 150 representatives from the 5th standing director unit and experts, scholars and enterprises from the superhard materials industry attended the conference. The meeting was chaired by Sun Zhaoda, secretary general of the Superhard Materials Branch.
Yan Ning, Chairman of the Superhard Materials Branch
First of all, Yan Ning, chairman of the Superhard Materials Branch, delivered a speech at the meeting. In his speech, he said that China's economy has shifted from a high-speed growth stage to a high-quality development stage. The transition from high-speed growth to high-quality development is an inherent requirement of the country's economic development. The super-hard materials industry is no exception. This exploration of new development models in an open state will create tremendous opportunities for the development of our industry in the country's new materials industry. China's superhard materials industry achieved a new leap in 2017 – the sudden emergence of diamond wire saws, the attention of CVD single crystal research and the emergence of new products such as NPD, all stem from the fact that Chinese superhard materials people never resign. The spirit of hard work is inseparable from the outstanding contributions made by all the companies present in the industry. In 2018, the association will carry out the re-election of the new council. The association will further play the role of bridges and joint efforts with industry colleagues to make the superhard materials association a more compact, cutting-edge and open industry platform for the overall progress of the industry. Make the due contribution.
Secretary General of the Superhard Materials Branch Sun Zhaoda
Then, Sun Zhaoda, Secretary General of the Superhard Materials Branch, reported on the work summary of the club in 2017 and the work plan for 2018. Secretary-General Sun Zhaoda pointed out that in 2017, with the joint efforts of all of you, the Association has achieved a series of new achievements in cooperation with the work of the General Conference, the operation of the Association, related activities of the Association, and the construction of the information platform of the Association. In 2018, the Association will be active in the industry. , industry information, industry services in three areas to improve service capabilities and levels, and promote industry work forward and better development.
In 2018, the association has organized related industry activities. In March, it participated in the Augsburg grinding exhibition in Germany. In April, it participated in the 10th China CNC Machine Tool Exhibition (CCMT2018). Important events such as the 15th Anniversary Celebration, the Association's change, and the preparations for the Guangzhou Sanma Exhibition. In terms of industry information, the association will next make group adjustments according to different sections. In the industry service, it will provide service services for member companies in terms of policy open source and cost reduction.
According to the agenda of the meeting, Li Zhihong, a senior consultant of the Superhard Materials Branch, gave a special report on the “2017 Economic Operation Brief Report on Superhard Materials Industryâ€. The report mainly includes 2017 national macroeconomic related data, major economic indicators of the industry, China Customs import and export statistics, US customs import statistics, Japanese customs import statistics, and summary of listed company annual reports.
Li Zhihong, Senior Consultant, Superhard Materials Branch
The report believes that the super-hard materials industry has successfully recovered from the bottom of the trough as the domestic and international markets recover and the endogenous power is enhanced by the troika. The production scale of gem-quality diamond single crystals and flaky single crystals for knives continues to expand. The growth of cubic boron nitride abrasives and polycrystals is large, the growth of tools and grinding tools is large, and the wire saws are exploding, and the industry has successfully entered. The finished diamond jewellery market; all kinds of products exported in an all-round way, diamond exports increased the most, the volume increased by 33%, the amount increased by 43%; but the sawing and drilling tools were affected by the lack of real estate growth, the growth rate is not large. The overall situation of the industry is improving.
According to the agenda of the meeting, the meeting also carried out the election of the new director and above candidates. After the meeting, the final candidate list will be discussed through the chairman meeting according to the number of votes received by each candidate.
According to the schedule of the meeting, the afternoon conference invited six industry experts to give special lectures. They are: Professor Wang Chengyong, Ph.D. supervisor of Guangdong University of Technology, “Application of Diamond in 3C Processing and Medical Treatmentâ€, Professor He Yuehui, Ph.D. Supervisor of Central South University, “Hybrid Bonding Agent Superhard Material Wheel and Its Application Technologyâ€, Beijing Science and Technology Professor Li Chengming, a doctoral tutor at the University, “Development Methods and Applications of Diamond Film Industrializationâ€, Professor Xie Jin, a doctoral tutor at South China University of Technology, “Diamond Precision Abrasive Technology for Ultra-precision Machiningâ€, Professor Zhang Fenglin of Guangdong University of Technology, “Energy Saving and Environmentally Friendly Metals†"Basic Research on Bonding Diamond Tools" and "Superhard Material Grinding Wheel Correction Technology" by Professor Feng Keming, Professor of Advanced Mechanics of Zhengzhou Abrasives Grinding Research Institute. The six special lectures deepened the theme of traditional application upgrade, emerging market development, and functional application development in the super-hard materials industry, expanding the ideas and visions of the participants in the application field of super-hard materials, and actively promoted the sustainable and healthy development of the super-hard materials industry. effect.
