In machine tool industry, general nc machine tools based on number of shaft, under triaxial for low-grade, three to five axis for high-grade, more than five axis for high-end.For industrial production equipment of traditional and modern distinction logo is the traditional machine tool and numerical control machine tool, it has become the industry consensus.Machine tools stand-alone intelligent and automatic nc machine tool is the direction of the machine tool industry, its high precision, high, high speed, flexible, intelligent, is a sign of modern industry.Modern equipment is developing towards extreme manufacturing industry, it is more and more big, the second is more and more small, 3 it is more and more complex, highly integrated production process.China machine tool industry after several generations of struggle, only simple production belt machine 1600 units from 1949 to 2008 machine tool production reached 617000 units, to become the world’s third largest producer of machine tools, more than 60 years of development, great changes have taken place in China’s machine tool industry, but compared with foreign high-end machine tools, or some of the gap, as long as embodied in the following three aspects;First, the accuracy, stability, reliability, etc.Five-axis linkage CNC machine tools such as foreign products for 1500 h without fault, domestically produced about 1000 h, differ to a second, the numerical control system.Numerical control system is the core of the nc machine tools, Germany’s Siemens, liebherr and Japan mazar-e-sharif, ferrari, hold the highest form of CNC system, liebherr for 16 packages close to the machine tool numerical control system, software and machine tools together to sell, not sold separately, software profit is very high.At present domestic machine tool companies use high-grade machine tool numerical control system of the basic are imported.Third, the other key fittings gap.Dalian machine tool can be 95% to the international advanced level to match, but the remaining 5% is not an enterprise even an industry can do, including steel raw materials, standard parts, screws, nuts, etc., need to increase the overall level of the country’s industrial.In addition, process, testing is to reach the world advanced level.
Germany’s annual industrial fair in Hanover, Germany in the end of April to the grand opening.Hannover messe is about to enter the 70th anniversary of the, has become the largest international industry event.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.Nc machine tool technology ability embodies the core competitiveness of a country’s manufacturing.China as the world’s largest manufacturing power, nc machine tools industry gets rapid development in recent years, the 2014 annual output of 391000 units, up 65% from 2010.But compared with the leading countries such as Germany and Japan, there is still a large gap, features, automation tools, CNC system to rely on foreign technical support.In 2014, for example, 90% domestic high-grade CNC system is still need to rely on imports.Technology research and development and breakthrough in the field of nc machine tool became & other;Throughout 2025 & made in China;Strategic important work.In this paper, an application for a patent for boring data, the perspective of global competition pattern, numerical control machine tool technology try to discuss the way of nc machine tool industry development in our country.Industrial 4.0 era, the updating cycle of nc machine tool technology into a new, industrial structure facing reshuffle until December 2016, 10708 globally CNC machine field.From the point of application trend, present explosive growth since 2006, and reached a peak around 2012.Current CNC machine patent filings entered the stage of fall, but also fallen sharply in 2016.As industrial 4.0 further advance, numerical control machine tool technology into a new round of update cycle, upgrading of technology will lead to the reshuffle of industry structure.China became the biggest patent output, but the lack of international competitiveness in a new round of technology update, the world’s major industrial countries are actively developing technology and patent layout.At present, China, Japan, the United States, Germany, is the main output of CNC machine patents, the four patents output more than 85% of the total.And among them, China has become the biggest patent output, the patent output of 6586 pieces, accounts for about 60% of the total filings.From accepted by the patent situation, China, Japan and the United States is the current numerical control machine tool technology is the most competitive areas.Although Chinese patent output is huge, but quantity is little, only 26, international competitiveness is weak., 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 United States and Germany nc machine patent output also is bigger, were 506 and 220 of them, also shows a strong international competitiveness.Japan, Germany technology precipitation highlights spirit, the Chinese technology accumulation foundation is still light from national patent application trends, 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 have focused on since 2005, thanks to & other;11th five-year plan & throughout;After the country to promote the development of manufacturing industry upgrade and and nc machine tool technology result in long-term development.But with Japan, Germany, compared to more than 40 years of precipitation technology accumulation lacking in China, shallow roots.Correlation degree is high, the key technology research and development need to break through the numerical control machine tool main patent points are control technology, processing technology, machine tool parts and related accessories, etc.From the point of patent applications, numerical control machine tool technology focused on the control technology (2827) (3505), processing technology and machine components (3286) three aspects.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.Owing to the high correlation between various types of technology, the development of key technologies need to break through, to achieve coordinated development.China needs to strengthen enterprise technology research and development ability, technology industry transformation ability to ascend 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.In the field of nc machine tools as an important development industry 4.0, key competitive field has become a major industrial countries.Nc machine tool industry in China with the support of national strategy, present a rapid development momentum in recent years, technological catch-up the momentum unstoppable.In a new round of industry development cycle, China is expected to technology research and development industry is increased by corner overtaking.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.
