            As China's 13th five-year plan, intelligent manufacturing covers industrial robots, CNC machine tools, 3D printing and other automatic devices.Through the series of articles, the author will be able to see the technological competitive pattern of the intelligent manufacturing industry through the trend of patent market in various fields.Since before "now very fire 3 d printing, we the gap with foreign counterparts how much?" and "ten picture see global industrial robot patent market and technology trends, a deep insight into the gap between our country and foreign 3 d printing technology and the global industrial robot technology development trend, the essay focuses on the analysis of intelligent manufacturing and a key areas - the competition situation of the nc machine tool technology, discuss the way of breakthrough of nc machine tool industry in China.



          The annual German industrial fair opened in Hanover, Germany, in late April.The Hanover industrial expo, which is about to enter its 70th anniversary, has become the largest international industrial gathering in the world today.This year the German industrial exposition will with 4.0 as the core industry, focus on industrial automation, leading in the field of digital factory, industrial parts and other industrial products.Nc machine tool as an important part of industrial automation and digital factory, is widely used in automobile manufacturing, metal processing, aerospace and other fields, is the foundation of industrial modernization.The technical ability of numerical control machine embodies the core competence of a country's manufacturing industry.


          China, the world's largest manufacturing powerhouse, has been rapidly developing in recent years, with a total of 39.1, 10, and a 65% increase in 2014.However, compared with the leading countries such as Germany and Japan, there are still large gaps, and the functional components, automatic tools and CNC systems are supported by foreign technology.In 2014, for example, 90% of the country's high-end CNC systems still depend on imports.The technological development and breakthrough in the area of nc machine tool is the important work of "made in China 2025".Through the tedious patent application data, this paper attempts to explore the development of nc machine tool industry in China by looking at the competitive pattern of global numerically-controlled machine tools.


          With the advent of industry 4.0, the technology of CNC machine has entered a new cycle of renewal, and the industry is facing a shuffle As of December 2016, the number of global applications for nc machine tools reached 10,708.From the trend of application trends, there has been a boom since 2006 and peaked around 2012.At present, the number of patent applications for CNC machines has fallen into a phased decline, and in 2016 there has been a significant decline.With the development of industry 4.0, the technology of nc machine has entered a new cycle of renewal, and the upgrade of the technology will inevitably lead to the reshuffle of the industry pattern.


          China is the biggest producer of patents, but the international competitiveness of technology is inadequate.


          In a new round of technological upgrades, the world's leading industrialized countries are actively engaged in technical and patent layouts.At present, China, Japan, the United States and Germany are the main producing countries for the patent for numerical control machine tools, and the number of patents in the four countries exceeds 85 percent of the total number of patents.In China, China became the largest producer of patents, with a total of 6,586 patents, about 60% of the total.China, Japan and the United States are the most competitive regions in the world of CNC machine tools.


          Although China's patent output is huge, there are only 26 foreign exports and a weak international competitiveness of technology., by contrast, Japan's foreign patent output up to 1121 pieces, including the Chinese output of 82 (4.06% of the total output), the output to the United States, 247 (12.24% of the total output), the German output 224 (11.10%) total output first, the technical ability to show a strong international competitiveness.In addition, the us and Germany have a large number of patents on CNC machines, 506 and 220 respectively, and they also show stronger international competitiveness.


          Japanese and German technology precipitates the craftsman spirit, the Chinese technology accumulation foundation is shallow From national patent application trend, Japan, Germany nc machine patent since the 1970 s has maintained relatively stable output, on the one hand reflects the nc machine tool technology of the two countries have a long time accumulation, on the other hand shows that Japan, Germany to the continuous development of technology and improvement of highlights Japan and Germany enterprise spirit of constant improvement on techniques.China an application for a patent for nc machine tools are mainly concentrated in 2005 years later, after the benefit from the "11th five-year plan", to promote the manufacturing industry upgrade and development of CNC machine tool technology result in long-term development.But compared with the technology in Japan and Germany over 40 years ago, China's technology is lacking and its roots are shallow.


          The key technologies are highly relevant, and technological development requires a comprehensive breakthrough.


          The patent points of CNC machine are mainly controlled technology, processing technology, machine tool parts, related accessories and so on.From the quantity of patent application, CNC machine technology focuses on control technology (2827), processing technology (3505) and machine parts (3286).


          From the control technology, processing technology and machine components technology patent application situation, the three key technologies has obvious correlation, the correlation coefficient of 0.95.Due to the high degree of correlation of different types of technology, the development of key technologies need to be fully breakthrough in order to realize the coordinated development.


          The technological development capability of Chinese enterprises needs to be strengthened, and the transformation capacity of the technology industry needs to be improved

    The applicant for a patent for the global top 20, the Japanese companies accounted for 11, Chinese enterprises (university), a total of four, compared with Japanese companies, the technical strength of Chinese enterprises has obvious disadvantage, enterprise technology research and development ability needs to be strengthened.In addition, look from the applicant for a patent for China's top 20, China's colleges and universities and research institutes with strong productive capacity of knowledge and technology, but did not really into industry, need to strengthen the university-industry cooperation, promote technology industry transformation ability.


          As an important development area of industry 4.0, nc machine has become the key competition area of major industrial countries.With the support of the national strategy, China's numerical control machine industry has shown rapid development in recent years, and the pursuit of technology is unstoppable.In the new cycle of industrial development, China is expected to overtake the industry by stepping up its technology research and development.Germany, however, Japanese enterprise technical advantage is the result of decades of excellence, continuous precipitation, Chinese enterprises can change the disadvantage of not day and night, the spirit of craftsman in Chinese companies only in the same - to keep the longing for the pursuit of high-end technology and technology, to create excellent enterprise competitiveness, stride towards industry, high-end field occupies advantageous position in the new round of industry competition.
