”I don't have much to say either. Starting from the grassroots level, I will raise some issues related to the grassroots. Hong Jiansheng, a member of the National Committee of the Chinese People's Political Consultative Conference and deputy chief engineer of AVIC, told reporters that during his tenure as a member, reporters visited the "Two Sessions" for three years and interviewed him three times. He always said the same sentence, and the proposals or suggestions he submitted were also very specific. One proposal is about the salary of retired personnel; He called on the country to increase support for the electronic fuel injection industry of diesel engines; This year, his proposal is about accelerating the application of domestically produced CNC machine tools.

Hong Jiansheng said that during the 11th Five Year Plan period, the country has successively launched 16 major science and technology projects, among which the "High end CNC Machine Tools and Basic Manufacturing Equipment" major science and technology project is one of them. The country has made great efforts to replace imported products with domestically produced CNC machine tools. In fact, it is our military industry enterprises that import more, and we are also criticized by others. However, due to the certain gap between domestic high-end CNC machine tools and foreign products in terms of performance, stability, reliability, etc., some machine tool manufacturing enterprises do not have enough research on related application processes. In addition, the requirements for equipment development are becoming increasingly high, which leads to a lack of confidence among users in using domestic machine tools. The promotion and application in the national defense and military industry are still constrained

Nevertheless, Hong Jiansheng still has confidence in domestically produced high CNC machine tools. He said that since the implementation of the specialized project, machine tool manufacturing enterprises have broken through multiple key technologies in the development of high-end CNC machine tools, and have developed various types of CNC machine tools. Some high-end CNC machine tools have been preliminarily applied in national defense and military enterprises, such as achieving small batch production of 12 typical aircraft structural components in a certain aviation manufacturing enterprise with 6 domestically produced high-end CNC machine tools; A certain aerospace manufacturing enterprise has adopted 10 domestically produced CNC machine tools with special support to carry out mass production of lightweight and high-strength materials, aerospace complex mechanisms, and components; Domestic high-end CNC systems and functional components have also achieved phased results. Hong Jiansheng believes that national defense and military enterprises are the main application units of high-end CNC machine tools. In order to ensure national strategic security and break the foreign blockade on high-performance machine tools, it is necessary to find ways to improve the research and development level of domestic CNC machine tools and achieve the goal of producing national defense equipment with domestically developed machine tools.

He suggested that the country further increase special investment in CNC machine tools, continue to implement the projects well, carry out joint research and development of industry, academia, research and application, meet the manufacturing equipment needs of the national defense industry, effectively reduce the dependence of national defense and military enterprises on imported equipment, and ensure national strategic security; Introduce relevant policies to encourage enterprises to use domestically produced high-end CNC machine tools, such as reducing the proportion of self raised funds and reducing taxes for purchasing domestically produced equipment in technological transformation investment, and guiding enterprises to purchase domestically produced high-end CNC machine tools; For equipment that cannot meet domestic demand but does need to be imported, domestic research and development should be arranged simultaneously, and joint research and development should be carried out by user enterprises and domestic machine tool manufacturing enterprises to meet the key indicators of imported equipment and meet user needs within a specified period of time.

Hong Jiansheng knows that in order to make domestic CNC machine tools reach the international advanced level, it is necessary to take the path of combining production, learning, research, and application. There is still a lot of work to be done on how to promote the integration of industry, academia, research, and application. The reason why our machine tools at AVIC Manufacturing Institute are effective is because they have a thorough understanding of the industry, "Hong Jiansheng said." We hope that the country will increase its support to tackle key technologies that affect the reliability and stability of machine tools, and promote the application of results
