Summary of the current situation of China's high-end CNC machine tools

Abstract: the most noteworthy thing is that the innovation, research and development and reliability level of China's machine tool industry have been significantly improved, and the machine tool industry standards and technical specifications have been gradually improved. Through the special implementation, the key domestic machine tool enterprises have been promoted to jointly develop with universities and users, and actively organize the preparation of national/industrial standards for reliability evaluation of CNC machine tools, so as to promote their application in the machine tool industry

machine tools are industrial machine tools, which are used to make machines. This is an important feature that distinguishes machine tools from other equipment. With the process of industrialization, the manufacturing industry can't only rely on the readings at the breaking point to meet the requirements of high-speed, precision and flexible manufacturing. The machine tool has gradually developed from an ordinary three-axis linkage machine tool to a high-end CNC machine tool such as high-speed precision composite machining and five axis linkage machining center, which realizes the machining of milling, drilling, boring and other processes in one-time clamping of workpieces, not only with high machining accuracy, At the same time, due to rapid movement and accurate positioning, the production efficiency is improved

as we all know, our country is the world's largest manufacturing country and the world's largest machine tool producer. However, there is a big gap between China and the international advanced level in the field of high-end computer equipment based on Visual Studio 2012. Through our efforts for many years, China has formed ten landmark achievements covering typical equipment in key fields such as aerospace, automobile and high-end machine tools, which basically represents the highest level of R & D and application of high-end machine tools in China. It has successively provided key manufacturing equipment for major national projects such as nuclear power and large aircraft, as well as a number of national key projects such as new fighters and launch vehicles, and has achieved breakthroughs in a number of key technologies and equipment, It has strongly supported and guaranteed national security

for example, the 80000 ton large die forging press and the 10000 ton aluminum plate tension such as the midpoint to the point of the figure are the successful development of heavy equipment such as the tensile machine in the strengthening stage, which fills the technical gap in the integral forming of large key parts in the domestic aviation field; A complete set of welding equipment for large fuel tanks has been successfully used in the development of new generation launch vehicles such as the Long March 5. The first demonstration production line using domestic machining centers and CNC turning centers has been established in the aerospace field. It has been applied to the processing of more than 100 kinds of key and complex parts such as the new generation launch vehicle and the lunar exploration project, and has achieved remarkable economic and social benefits. The industrialization of NC forging and forming equipment has achieved remarkable results. Among them, the high-efficiency automatic stamping production line for large automotive panels has reached the international leading level, with a domestic market share of more than 70% and a global market share of more than 30%

since the implementation of the special project of CNC machine tools in 2009, the technical level of the industry has been significantly improved, and the gap with the international advanced level has been narrowed. The development of more than 30 types of key products such as precision horizontal machining centers has reached the international level. 4. Experimental space (excluding piston stroke): 7m; Advanced level. Among them, the 25m column mobile vertical milling lathe is urgently needed for the construction of national major projects. Its technical parameters and technical grade are at the world leading level, and the machine tool specification is the largest in the world, representing the highest level of national high-end CNC heavy machine tools. With the special support of CNC machine tools, China's CNC system has achieved a leap from analog, pulse to full digital bus. The main technical indicators of high-performance CNC system series products such as multi-channel and multi axis linkage have basically reached the level of international mainstream high-end CNC systems. At present, the domestic high-end CNC system has been matched with more than 10 categories of 600 high-end CNC machine tools, and has begun to be demonstrated and applied in key aerospace enterprises. The product quality level of functional parts enterprises has been steadily improved, and the variety series has been continuously improved. Up to now, the rolling functional parts have a market share of 20% in the middle and high-end CNC machine tool market, which is 4 times higher than that in 2009, and the variety satisfaction has reached 80%

what is worth mentioning most is that the innovation, research and development and reliability level of China's machine tool industry have been significantly improved, and the machine tool industry standards and technical specifications have been gradually improved. Through the special implementation, the key domestic machine tool enterprises have been promoted to jointly develop with universities and users, and actively organize the preparation of national/industrial standards for reliability evaluation of CNC machine tools, so as to promote their application in the machine tool industry. The mean time between failures of machine tool hosts has generally increased from hours before the special implementation to 1200 hours, and some products have reached more than 2000 hours, close to the international advanced level. The special achievements have formed a large number of technical standards and specifications, significantly enhanced the international competitive advantage of the industry, formed strong support for product research and development, and also played a role in ensuring the improvement of the sustainable development capacity of the national equipment manufacturing industry. In December 2016, the S-shaped test piece standard independently proposed by China for testing five axis linkage machine tools was approved by the International Standardization Committee, becoming the first standard in the field of high-end CNC machine tool design and testing, achieving a zero breakthrough

2017 is a year of great significance for carrying forward the past and opening up the future. We will continue to work hard to thoroughly implement the innovation driven development strategy and the manufacturing power strategy. Guided by the special implementation plan for CNC machine tools and the objectives of the 13th five year plan, and with the top ten landmark achievements as the starting point, we will focus on the two user fields of aerospace and automobile, and pay equal attention to the research of common technologies and the process verification in key fields, The research and development of key functional components go hand in hand with the development of industrialization, accelerate the construction of innovation capability platforms and demonstration projects, strengthen the cultivation of innovative talents and the introduction of high-end talents, focus on solving three aspects of machine tool systems and functional components, reliability and accuracy retention, processing efficiency and process level improvement, and realize the large-scale and complete set demonstration application of special achievements in key fields, so as to provide support for the full implementation of "made in China 2025"

the "aircraft carrier" of China's machine tool and equipment industry has been testing the water. 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
