How to overtake CNC machine tools in the corner wh

"Industry 4.0" era is coming. How can China's CNC machine tools overtake in the corner

CNC machine tools are an important part of industrial automation and digital factories, which reflect the core competitiveness of a country's manufacturing industry. China is accelerating the layout of technologies and patents in the field of CNC machine tools

the annual German Industrial Expo was grandly opened in Hanover, Germany, at the end of April this year. The Hannover Industrial Expo, which is about to enter the 70th anniversary, has become the largest international industrial event today. With industry 4.0 as the core, this year's German Industrial Expo will focus on the exhibition of leading product achievements in industrial automation, digital chemical plants, industrial components and other industrial fields. As an important part of industrial automation and digital factory, CNC machine tools are widely used in automobile manufacturing, metal processing, aerospace and other fields, and are the cornerstone of industrial modernization. The technical ability of CNC machine tools reflects the core competitiveness of a country's manufacturing industry

as the largest manufacturing country in the world, China's CNC machine tool industry has developed rapidly in recent years, with the output reaching 391000 units in 2014, an increase of 65% over 2010. However, compared with leading countries such as Germany and Japan, there is still a large gap. The functional components, automatic detection of two goats, chemical cutting tools, and numerical control system rely on foreign technical support. For example, 90% of domestic high-end CNC systems still need to be imported in 2014. Technological research and development and breakthroughs in the field of CNC machine tools have become an important part of the "made in China 2025" strategy. Through the boring patent application data, this paper analyzes the global competition pattern of CNC machine tool technology, and tries to explore the development path of China's CNC machine tool industry

with the advent of industry 4.0, CNC machine tool technology has entered a new round of renewal cycle, and the industrial pattern is facing a reshuffle.

as of December 2016, the global application volume in the field of CNC machine tools has reached 10708. From the perspective of application trend, the clamping mode of the explosive fixture has developed from the original mechanical clamping to pneumatic clamping and hydraulic clamping since 2006, and reached a peak around 2012. At present, the number of patent applications for CNC machine tools has entered the first three quarters of this year, and 80% of enterprises achieved a phased decline in year-on-year net profit growth, and there was a sharp decline in 2016. With the further development of industry 4.0, CNC machine tool technology has entered a new round of renewal cycle. The renewal of technology will inevitably lead to the reshuffle of the industrial pattern

China has become the largest patent producer, but the international competitiveness of technology is insufficient

in the new round of technological upgrading, the world's major industrial countries are actively carrying out technology and patent layout. At present, China, Japan, the United States and Germany are the main producers of CNC machine tool patents, and the patent output of the four countries exceeds 85% of the total patents. Among them, China has become the largest patent producer, with 6586 patents, accounting for about 60% of the total applications. From the perspective of patent acceptance, China, Japan and the United States are currently the regions with the most fierce competition in CNC machine tool technology

although China's patent output is huge, the export volume is small, only 26, and the international competitiveness of technology is weak. In contrast, the export of Japanese patents is as high as 1121, including 82 to China (accounting for 4.06% of the total export), 247 to the United States (accounting for 12.24% of the total export), and 224 to Germany (11.10% of the total export first). Its technical capacity shows strong international competitiveness. In addition, the United States and Germany also have a relatively large number of CNC machine tool patents, 506 and 220 respectively, which also show strong international competitiveness

the technological precipitation of Japan and Germany highlights the spirit of craftsmanship, and the foundation of China's technological accumulation is still shallow.

from the trend of patent applications in various countries, Japan and Germany have maintained a relatively stable output of NC machine tool patents since the 1970s. On the one hand, it reflects the long-term accumulation of NC machine tool technology in these two countries, on the other hand, it shows the continuous research and development and improvement of technology in Japan and Germany, It highlights the craftsmanship spirit of Japanese and German enterprises to strive for technological excellence. China's CNC machine tool patent applications are mainly concentrated after 2005. Thanks to the "Eleventh Five Year Plan", the country has promoted the upgrading and development of the manufacturing industry, and the CNC machine tool technology has made great progress. However, compared with the technological precipitation of Japan and Germany for more than 40 years, China's technological accumulation is deficient and its foundation is still shallow

the relevance of key technologies is high, and technological research and development needs a comprehensive breakthrough.

the patents of CNC machine tools mainly include control technology, processing technology, machine tool parts, related accessories, etc. Judging from the number of patent applications, CNC machine tool technology focuses on three aspects: Control Technology (2827), processing technology (3505) and machine tool components (3286)

from the patent application situation of control technology, processing technology and machine tool component technology, these three key technologies have obvious correlation, and the correlation coefficient is about 0.95. Due to the high relevance of various types of technologies, the development of key technologies needs a comprehensive breakthrough in order to achieve coordinated development

the technology R & D capability of Chinese enterprises needs to be strengthened, and the transformation capability of technology industry needs to be improved.

among the top 20 patent applicants in the world, 11 are Japanese enterprises, and 4 are Chinese enterprises (universities). Compared with Japanese enterprises, the technological strength of Chinese enterprises has obvious disadvantages, and the technology R & D capability of enterprises needs to be strengthened. In addition, from the top 20 Chinese patent applicants, Chinese universities and scientific research institutions have strong knowledge and technology output capacity, but they have not been truly transformed into industrial achievements. It is necessary to strengthen industry university cooperation and improve the technology industry transformation capacity
