recently, The Ministry of science and technology, together with the Ministry of industry and information technology, organized a press conference on the major national scientific and technological achievements of "high-end CNC machine tools and basic manufacturing equipment", which introduced the gratifying achievements made in the special implementation of CNC machine tools for more than 8 years

significant achievements in overcoming difficulties

"CNC machine tools are the 'working machine' of industry. The development of high-end CNC machine tools is not only the objective need of the supply side structural reform in the field of industry and information technology and accelerating the construction of a manufacturing power, but also the urgent requirement of realizing the in-depth development strategy of military civilian integration and ensuring national security. Since the special implementation of CNC machine tools for more than eight years, the majority of machine tool enterprises, user enterprises and experts have worked together to overcome difficulties and achieved a number of gratifying results 。” Luo Junjie, deputy director of the equipment industry department of the Ministry of industry and information technology, said

it is reported that since the early implementation of the special program in 2009, the special program of CNC machine tools has focused on the research and development of machining centers and CNC lathes with wide market demand. At the end of the 12th Five Year Plan, the product design and manufacturing capacity of China's machine tool enterprises has been significantly improved, and the international competitiveness of high-end CNC machine tools and equipment has been continuously enhanced. Machine tool enterprises have developed a large number of new products to meet the market demand. Manufacturing technologies such as gantry machining center and five axis machining center are becoming mature. The performance of heavy forging equipment is close to the international advanced level. Precision horizontal machining center has formed the core technology of flexible manufacturing system with independent intellectual property rights

industry development, standards first. Through the special layout and effective implementation of CNC machine tools, the industry standards and technical specifications of machine tools have been gradually improved. According to Lu Bingheng, academician of the Chinese Academy of engineering and chief technical engineer of CNC machine tools, at the end of 2016, the S-shaped specimen standard independently proposed by China for testing the accuracy of five axis linkage machine tools has been approved by the International Standardization Committee, which has achieved a breakthrough in the "zero" standard in the field of high-end CNC machine tool testing

CNC system is the "brain" of machine tool equipment, the key factor determining the function, performance, reliability and cost price of CNC machine tools, and also the bottleneck restricting the development of China's CNC machine tool industry. The weak foundation and "lack of heart and brain" have always been the weakness of "made in China". Numerical control system, servo motor and servo drive are the most important basic components of manufacturing equipment. To achieve the goal of "made in China 2025" and form the core competitiveness of "made in China", we cannot do without the innovation of key technologies such as CNC system, including servo drive and servo motor

the special deployment of CNC machine tools implements the layout of the whole industrial chain, and the domestic CNC system realizes the original transcendence of some technologies (such as embedded integrated CNC device hardware platform, etc.). The enterprise has mastered the software and hardware platform design and mass production technology of CNC system, and has reached the international mainstream product technology level in key technical indicators such as multi-channel, multi axis linkage, high-speed interpolation and so on. In 2016, more than 1000 sets of high-end CNC systems developed with the special support of CNC machine tools have been sold, and the domestic market share has increased from less than 1% before the special launch to about 5%. The mid-range CNC system has achieved mass production, and the domestic market share has increased from 10% to 25%. Three industrial production bases have been formed, and the sales of CNC systems specially supported have reached nearly 4billion yuan. Ball screw, guide rail, power tool rest and other key functional components have approached the international advanced level in terms of precision, reliability and other key indicators

since the special implementation of CNC machine tools, the equipment support capacity in key areas has been continuously improved

the high-end CNC machine tools represented by the five axis machining center have achieved batch demonstration applications in the fields of typical aircraft structural parts, aerospace complex and precision structural parts, aircraft missile engine parts and components, and provided key manufacturing equipment for major national special projects and key projects such as large aircraft, new fighter aircraft, lunar exploration project, etc. For example, the successful development of "large-scale heavy equipment" such as 80000 ton large die forging press and 10000 ton aluminum plate tension stretching machine marks that China's aviation profile manufacturing has entered the world's advanced ranks; Complete sets of welding equipment for large storage tanks, large powerful spinning equipment, automatic drilling and riveting equipment and other special aerospace manufacturing equipment have provided strong support for the successful launch missions of Long March 5 and Tianzhou 1. In the field of automobile manufacturing, the large-scale fast flexible automatic stamping production line developed by Ji'er has successfully exported 9 production lines in the past five years, with a domestic market share of more than 70% and a global market share of more than 30%

"China is the largest manufacturing country in the world today. At the beginning of the implementation of the special project, there was a large gap between China and the international advanced level in the field of high-end manufacturing equipment. Through the eight-year guidance and drive of the special project, ten landmark achievements covering typical equipment in key fields such as aerospace, automobile and high-end machine tools have been formed, which basically represents the R & D and response of China's high-end machine tools and equipment. The overall strength of China's new material industry will leap to the forefront of the world It has successively provided key manufacturing equipment for nuclear power, large aircraft and other major national projects, as well as a number of national key projects such as new fighter planes, carrying fire pair spring seat arrows, and has achieved breakthroughs in a number of key technologies and equipment, effectively supporting and ensuring national security. " Lu Bingheng said

facing the future, facing the wind and fighting the waves

although the special project of numerical control machine tools has made certain development achievements, with the rapid development of the international machine tool market and technology, we should also see that China's high-end numerical control machine tool products still have a certain gap with the international advanced level in terms of reliability and accuracy retention, and at the same time, they are in networking and intellectualization with the foreign machine tool industry There are also risks of further widening the gap in terms of group connectivity and system solutions

as for the future development, Luo Junjie said that the special project of CNC machine tools will deploy the innovation chain around the industrial chain, improve the capital chain around the innovation chain, comprehensively improve the R & D, manufacturing and industrialization level of key parts represented by the recycling method control system with a few but there are still rough landfills in some places, and strive to overcome the reliability and accuracy retention technology of machine tools; Increase application verification and demonstration, meet the new needs of the national strategy, and provide support for the full implementation of "made in China 2025". At the same time, we will continue to explore the long-term mechanism of industrial generic technology research, further consolidate the foundation of technical research and high-end talents, continue to strengthen the implementation of process validation in the manufacturing process of special research and development equipment and demonstration application in the user field, optimize product performance, and improve reliability, set-up process and intelligence. On the basis of the long-term cooperation mechanism of military machine tools, we will continue to promote the in-depth cooperation between domestic CNC machine tools and the military industry, actively build a production and demand docking platform between the machine tool industry and key areas such as military industry and automobile, and have machine tool enterprises jointly carry out pre research with users to provide users with complete sets of solutions including equipment and typical process solutions

"the 'aircraft carrier' of China's machine tool and equipment industry has tested the water and moved forward. Over time, the 'giant ship' of China's machine tool and equipment industry will face the wind and waves in the tide of globalization of the world economy." Lu Bingheng said that Qu Jinping, an academician of the Chinese Academy of engineering and professor of South China University of technology, believes that China's high-molecular material industry is large but not strong from a technical perspective. In the next step, the special project of CNC machine tools will be closely linked with other national and local science and technology projects to form a joint force, and jointly commit to the leapfrog development of the innovation and R & D capacity of national high-end CNC machine tools and basic manufacturing equipment
