China is the first country in machine tool consumption in the world, but there is still a big gap between China's CNC machine tools in design, materials, technology, parts processing and other aspects. Therefore, the production capacity of the high-end CNC machine tools is very low in China, and a large number of high-end CNC machine tools are still imported from abroad every year. In the future, the development trend of machine tools will gradually develop towards automation, intelligence and green.
"The emergence of intelligent machine tools can effectively liberate people, improve production efficiency, reduce unnecessary labor costs, but also make machine tools more precise in production process." Shijiazhuang Zhongshan mould factory Chang Mao qui said in an interview with reporters that the emergence of intelligent machine tools created conditions for the production automation of the future equipment manufacturing industry. It combines precision manufacturing technology and computer and network technology, and is the main development direction of machine tools in the future.
In its work, intelligent machine tools can monitor, diagnose and modify various kinds of deviations in the process of production, and can provide solutions for the optimization of production and adjust in real time. It is impossible for traditional machine tools to do it. Mao Wenkui said that intelligent machine tools can effectively improve production efficiency, and compared to traditional machine tools, making precision parts will be more easy and convenient, can also reduce the production of waste parts, reduce production costs.
In addition, because of the high automation, intelligent machine tools can reduce the input of human cost, and let people have time and energy to deal with the problems that more intelligent machine tools can't solve. This is a very important step for the transformation of traditional manufacturing industry. Without cumbersome operation, the manpower will be liberated more frequently from repetitive mechanical labor, approaching automation or even full automation.
According to relevant analysis, the development of information technology and its integration with traditional machine tools make the machine tool develop towards digitalization, integration and intellectualization. The application space of digital manufacturing equipment, digital production line and digital chemical plant will be more and more large, and intelligent technology is used to realize the intelligent decision making, process adaptation control, error compensation intelligent control, complex surface machining trajectory optimization control, fault self diagnosis and intelligent maintenance under multi information fusion. Information integration and other functions will greatly improve the accuracy of forming and machining, and improve manufacturing efficiency.
However, although our country has been committed to developing intelligent machine tools with independent intellectual property rights, there is still a certain gap with the industrial production countries at this stage. The lack of patent technology is still the main reason for restricting the development of intelligent machine tools in China, and the concern for R & D and innovation of enterprises is not conducive to the development of intelligent machine tools in our country.
The problem remains
From imitation assembly to introduction and absorption to acquisition cooperation, the distance between China's manufacturing and its rivals is getting closer and closer, and the technology blockade encounters more and more stringent. But the realization of innovation drive and transformation and upgrading is the only way to move towards "China's intellectual creation". Reconstructing the key common technology research and development system is a must for China's manufacturing transformation.
"The main R & D unit of our country's intelligent machine tools is still more than the old state-owned enterprises, but the drawbacks of the state-owned enterprises are that it seems a little flinch for innovation." A person who did not want to be named told reporters that most of the leaders of state-owned enterprises had appointed systems, and most of them had a definite term of office. The leaders of some state-owned enterprises believe that the success of innovation may be the right one. Once the failure, it may lose fame and fortune, and that is why some companies have been cautious about innovation.
Related people say that some state-owned enterprises have a hard time for Innovation: the first is that the manufacturing industry has a small profit, a large amount of R & D investment will eat the profit, and the performance will not look good. Two is the chairman of the enterprise, often in a few years will change places, lack of long-term innovation strategy. The three is that R & D investment exceeds a certain limit, so it is difficult for enterprises to make decisions.
However, the core technology can not be mastered without innovation. Hu Wei, a researcher at the Shijiazhuang Institute of science and technology, told reporters that "foreign technology craving for China is becoming more and more stringent, and how to develop intelligent machine tools with independent intellectual property rights has become the key to the transformation of the machine tool industry and even the whole manufacturing industry in our country."
In addition, there is no uniform standard for intelligent manufacturing in China, which hinders the healthy development of intelligent machine tools in China. Under the guidance of the Ministry of industry and information and the National Standardization Management Committee, the first International Forum on "standardized Internet Intelligent Manufacturing" of the equipment manufacturing industry, sponsored by the China aeronautical Comprehensive Technology Institute, the director of the China Institute of electronic technology standardization and the Secretary of the China integrated Standardization Working Group on intelligent manufacturing Hu Jingyi pointed out that standards are the key to the success of intelligent manufacturing, and standards will lead to the further development of intelligent manufacturing.
In the context of great changes in information technology, standardization has become a necessary condition for interconnection of intelligent manufacturing systems. Experts say that the realization of intelligent manufacturing needs to build a large and complex system. Information systems, production and manufacturing systems, and automation systems should interact in the whole life cycle of product design, production, logistics, sales and service, and a consistent standard is needed as a guarantee. In addition, standardized terms and definitions can help participants to communicate and communicate with each other so as to achieve the whole line.
Policy support is still the key
Looking at the equipment manufacturing industry and the level of equipment manufacturing industry, we can see the importance of the machine tool industry as the "mother of industry" in industry. China is the first largest machine tool manufacturer in the world, but it is also the largest importer of machine tools in the world. The main reason for this contradiction is that China's machine tool technology is backward.
There are relevant reports that the machine tool industry in China has fallen into a very difficult situation, and the regular product market has fallen seriously, resulting in a decline in the overall output, the decline of income, the greater loss of personnel, the less professional technicians and professional designers, the large investment in the research and development of high performance products, and the difficulty of financial investment, which is far below the expected profit. The development of new products is in a dilemma; the financial support of the banks for the real economy is poor, resulting in insufficient funds for many customers.
Mao Wenkui told reporters that in recent years, China's machine tool demand has declined obviously, although China's machine tool industry has achieved certain achievements in the past, but the core technology is still in the hands of foreign related enterprises, and the homogenization is too serious caused the machine tool industry to still be mainly low-end products in the market, and the lack of competitiveness in the market.
Hu Wei said that we need policy support to change the existing problems in China's machine tool industry. He told reporters that the government should strengthen the support of intelligent CNC machine tools, reduce tax revenue, encourage banks to relax the funds for CNC machine tools enterprises, so that these enterprises can concentrate on increasing the R & D ability of the key parts of machine tools, and finally form the competitive advantage of the supporting industrial chain of machine tool manufacturing enterprises.
In addition, we should increase the training of relevant technical personnel, and strengthen the construction of machinery manufacturing majors in various vocational colleges and universities. Colleges, universities, scientific research institutions, intermediaries and enterprises should be encouraged to integrate the technology, achievements, talents, equipment and other innovative factors effectively and improve the independent innovation ability of the industry.
Hu Wei told reporters that the homogeneity will become the main target of the machine tool industry, the competition in the machine tool industry has changed into the competition of technology and innovation, and the various types of CNC machine tool enterprises are seeking new development and integration. Through integration, we can reduce the disorderly competition among industries and improve the scientific research ability, thus promoting the healthy development of China's machine tool industry.
