On May 10, 2021, the Provincial Industrial and Information Industry Affairs Center jointly conducted research on the machine tool industry. Ni Donghai, Secretary of the Party Committee and Director of the Industry Affairs Center, Mr. Xu Shixiong, President of the Association, Chairman of Changsha Numerical Control Equipment Alliance and Chairman of Yuhuan Numerical Control, He Jianguo, Chief Expert of Provincial Machinery Industry Association, and leaders of relevant offices in Changsha County and Changsha Economic Development Zone went deep into Changsha First School, Jinling Stock Company, Southern Machine Tool and Yuhuan Precision to investigate and understand the development of enterprises. President Liang Yu of Beijing Machine Tool Magazine was invited to conduct an in-depth interview with Hunan Machine Tool.

The machine tool industry is a manufacturing industry that provides processing equipment. It is the technical foundation and core of the modern equipment manufacturing industry and is known as the "industrial mother machine". It is also an important part of the advanced manufacturing highland and technological innovation highland in Hunan's implementation of the "three highs and four new" strategy. This research plan for key machine tool enterprises lasted two months, aiming to fully understand the current situation of the machine tool industry in our province, promote the high-quality development of the industry, and promptly propose policy recommendations for industry development to the provincial party committee and the provincial government.

Changsha Economic Development Zone has become a gathering and radiation area of Hunan machine tool industry, and has gathered 8 CNC machine tools and automation enterprises.

In recent years, a school of CNC has performed well in the field of linear motors. As a key functional component, linear motor has the characteristics of high positioning accuracy and fast speed, and has been gradually accepted and adopted by the market in recent years. At present, a school is developing a large thrust linear motor, such technology for the "stuck neck" project. One faction will focus on solving the problem of foreign technical blockade, and develop products that fully replace imported products, so that the core components of my country's high-end CNC machine tools have a complete domestic supporting chain.

In Jinling Co., Ltd., Chairman Lei Limeng introduced in detail the company's adherence to the development of "precision, high efficiency, complete set and intelligent" overall solution. The exhibition hall of Jinling Co., Ltd.'s fist product CNC machine tool flexible intelligent production line attracted the research team to stop and watch. This is a high-precision, high-efficiency, parametric and modular core patented technology, which is used for flexible intelligent production lines of spindle products. At the production site, Secretary Ni Donghai came to the front of the machine tool equipped by Chen Yong, a guide rail bed scraping technician, to have a cordial conversation with him, to understand the working and living conditions, and to encourage Chen Yong to give full play to the skills of craftsmen in big countries, to stand on his post and to make more contributions to China's machine tool industry and regional economic development.

Hunan Southern Machine Tool inherits the talents and technology of the former Changsha Machine Tool Factory, and is engaged in the R & D and manufacturing of broaching equipment and special machine equipment. We have successively improved and developed double-guide column high-speed broaching machines, main bearing cap broaching machines, flange and through shaft end face tooth broaching machines, turbine disc tenon and groove broaching machines, condenser tube inner valve plane broaching machines, chain rail joint nut broaching machines and other new structures and new performance broaching machines. We have produced and manufactured many automatic broaching production lines including intelligent automatic loading and unloading mechanism, intelligent online detection, intelligent equipment diagnosis and so on for well-known domestic auto parts.

Hunan Yuhuan Precision System Yuhuan CNC Holding Subsidiary. The company was established in 2020 and has a strong momentum of development. The five-axis machine tools developed and produced by the company have become the new darling of the 3C electronics industry. It has also further increased market and technology development for Yuhuan, strengthened the company's competitive advantage in the field of grinding and polishing, and jointly promoted the rapid development of the company's business and improved the company's comprehensive Competitiveness.

After the field investigation, the research team held a forum in Yuhuan Intelligent Science and Technology Park. The person in charge of each enterprise introduced the company's development, existing difficulties and policy suggestions one by one. President Xu Shixiong pointed out in his speech that after years of industrial accumulation and technological precipitation, Hunan machine tool industry has formed a development pattern of "one main body and two wings. Relying on scientific research and innovation platforms such as the High Efficiency Grinding Engineering Technology Research Center of Hunan University, the "grinding" technology advantages of Hunan machine tools are prominent and fruitful. The "broaching and turning" subdivision has obvious characteristics and a good development momentum. In the future, Hunan Machine Tool will strive to increase the proportion of replacing imports in the machine tool host sector, and achieve new breakthroughs in key functional components such as linear motors and tool industries such as band saw blades. President Xu suggested that government departments should increase their support for the machine tool industry. They can increase the research on common technologies in the industry through the establishment of the Machine Tool Basic Technology Research Institute. The second is to help the machine tool industry through "decompression and supplement. Such as tax relief, the establishment of Hunan machine tool major development projects and so on. Third, it is recommended that government departments increase the management and training of association staff.

After listening to the report, Ni Donghai said that he appreciated the industrial feelings of President Xu and other responsible persons of machine tool enterprises. He stressed that the industry affairs center must go deep into the enterprise, earnestly understand the enterprise situation and development difficulties, issue industry development report and policy recommendations as soon as possible, and boost the high-quality development of Hunan machine tool industry.
