Major scientific and technological projects help China's high-end CNC machine tools, such as the display value on the display panel of the workstation is still incorrect, industrial development

for most people, CNC machine tools are a distant existence, but high-end CNC machine tools are the cornerstone of national industrial modernization, and they are even taken as an important symbol to measure a country's industrialization internationally. In 2009, China launched the major scientific and technological project of "CNC machine tool project". On June 26, the Ministry of science and technology and the Ministry of industry and information technology introduced the progress made in the eight years since the implementation of the special program

China is the largest manufacturing country in the world, but it has always been controlled by others in the field of high-end manufacturing. One important reason is that high-end digital machine tools and basic manufacturing equipment due to their inert characteristics. Academicians and experts at the meeting hope to take advantage of the meeting opportunities to show weakness, mainly relying on imports. In order to fundamentally solve these problems, the major science and technology project of "high-end CNC machine tools and basic manufacturing equipment" (i.e. "CNC machine tool project") was officially launched and implemented in 2009

after eight years of development, certain achievements have been made in the special project of CNC machine tools, which has not only solved the problem from "yes" to "no" in many fields, but also reached the international advanced level, Luo Junjie, deputy director of the equipment industry department of the Ministry of industry and information technology, said, "of the 57 key host products established at the beginning of the special implementation, 38 have reached or approached the international advanced level. The mean time between failure of machine tool hosts has generally increased from 400-500 hours (before the special implementation) to 1200 hours, and some products have reached the international advanced 2000 hours."

Luo Junjie also said that some domestic manufacturing equipment has also been exported. "In the automotive field, our large panel automatic stamping production line currently has a domestic market share of more than 70% and a global market share of more than 30%, and has been successfully exported to 9 production lines in the United States, including Ford, which has imported our panel stamping line."

domestic high-end digital machine tools also provide key manufacturing equipment in major national special projects and key projects such as domestic large aircraft, new fighters, and the lunar exploration project

at the same time, China is also actively improving machine tool industry standards and technical specifications. Five axis CNC machine tools are the representatives of high-end CNC machine tools. In December 2016, the S-shaped specimen standard independently proposed by China for testing the accuracy of five axis CNC machine tools was approved by the international standards committee, which achieved a breakthrough in the "zero" standard in the field of high-end CNC machine tool testing. According to Lu Bingheng, chief technical engineer of CNC machine tools, academician of the Chinese Academy of engineering and professor of Xi'an Jiaotong University, this will spur the machine tools produced in China to reach the international advanced level. "We are very happy and proud that we have put forward China's first standard and passed it. But on the other hand, if our machine tools fail to meet this standard, we will be miserable, and we will not be able to enter the international trade. The current market is like this: if the products fail to enter the international advanced level, too fast or too slow will lead to different test results, and we will not be able to achieve market share. This is also our special project A huge challenge. "

indeed, with high standards, we need high-quality products. Although the development of high-end CNC machine tools in China has made great progress, there is still a gap with the international advanced level in terms of reliability and accuracy; There are risks of further widening the gap in networking, intelligent and systematic solutions. What to do in the face of gaps and risks? Luo Junjie, deputy director of the equipment industry department of the Ministry of industry and information technology, introduced the next development plan of the digital machine tool project: "In the next step, we should strengthen the efforts of special projects, and revise the 13th five year plan according to the requirements, so as to better integrate the current actual needs and promote the better development of special projects; second, we should better focus on the key points, achieve key breakthroughs, and drive the development of the whole industry from point to area; third, we should increase the alliance with enterprises and users, and better promote the testing of innovation achievements in enterprises and users, and verify them through practice And promotion
