China's machine tool industry is not strong. China's machine tool industry has a prominent product structure contradiction. Key functional components such as medium and high-end CNC machine tools and their CNC systems are mainly imported. According to Luo Baihui, the head of the International Association of Mold and Hardware and Plastics Industry Suppliers, through the introduction of technology and joint ventures to developed countries such as the United States, Japan, Germany and Switzerland, and independent research and development, in the context of the rapid development of China's manufacturing industry, China's machine tool industry has achieved With rapid development, the proportion of CNC machine tools has also increased. The numerical control rate of output and output value of metal cutting machine tools has increased from 8% to 22% in 2000 to 29.6% and 52.5% in 2010. At present, the numerical control rate of machine tool output and output value in China is about 30% and 50% respectively, which is still different from 60-70% and 80-90% in developed countries. In 2007, the economical and mid-range of CNC machine tools produced in China The ratio of high-end to high-end is about 70:29:1, while in Japan and the United States are 0:80:20 and 0:60:40 respectively; the core CNC system of CNC machine tools, the market share of domestic mid-range CNC system is about 20%, high-grade CNC The system occupancy rate is less than 5%, which is heavily dependent on imports. China's machine tool enterprises are not strong, the industry concentration is low, and the low-end melee is at a high level. The backwardness of key accessory parts and products is an important reason for the backward development of CNC machine tools. The development of the downstream equipment industry has launched strategic opportunities, and the import substitution space is broad. The state has formulated special plans for high-end CNC machine tools and basic manufacturing, mainly for the high-end CNC machine tools in China's aerospace, shipbuilding, automotive and power generation equipment industries, and by encouraging the use of domestic CNC machine tools and supporting domestic machine tools on major projects. Encourage the development of high-end CNC machine tools; taking into account the current domestic and international gaps, import substitution space is huge.

Luo Baihui, head of the International Association of Mould & Hardware Plastics Industry Suppliers, believes that the demand for machine tools comes from fixed assets investment in the downstream equipment manufacturing industry. China's automotive, aerospace, defense, military, shipbuilding, power equipment, rail transit equipment, construction machinery, molds The rapid development of electronic information equipment and other fields has brought momentum to the machine tool industry. In the "Twelfth Five-Year Plan" and in the longer term, China will carry out large-scale and deep-level industrial restructuring, which will bring huge opportunities to the machine tool industry, especially high-end CNC machine tools. The machine tool industry will usher in the era of industrial robots. The key application of industrial robots lies in motion control, and motion control is an important factor in ensuring the accuracy of machine tools. From this perspective, machine tool manufacturing is very relevant to robot manufacturing technology. It is no wonder that the enthusiasm of machine tool companies involved in industrial robot manufacturing has increased in recent years. Especially CNC system manufacturing companies, such as Huazhong CNC, Guangzhou CNC. Industrial robots are currently mainly used in the automotive industry in China, and the cost is high. Industrial robots for machine tool loading and unloading will become a trend in the future. Guangzhou CNC is committed to producing robots that users can afford while ensuring that robots are fully functional and stable and reliable. It is understood that Guangzhou CNC has been involved in the research and development of industrial robots a few years ago, and has made breakthroughs: the company will first use dozens of robots in mass production in its own production workshop. Not only the CNC system manufacturing enterprise, but also the machine tool enterprise is very popular in the robot field. For example, Dalian Machine Tool exhibited its machining center and double spindle for the China National Nuclear Corporation at the 6th China CNC Machine Tool Exhibition held this year. A flexible machining island consisting of a CNC lathe and a robot. In this regard, Wu Bolin, executive vice president of China Machine Tool Industry Association, also commented that the flexible processing island produced by Dalian Machine Tool has guided the transformation of production organization, fully explaining the profound meaning of industrial automation and the main production mode of future manufacturing. . Coincidentally, Guan Xiyou, chairman of Shenyang Machine Tool Group, the number one in domestic machine tool sales, also said that Shenyang Group is preparing to cut into the field of industrial robot manufacturing. He told reporters that because the company has experience in developing the Feiyang CNC system, it is of great benefit to the development of industrial robot products. The high degree of technology relevance and the rapid growth expected in the future are two major factors that have prompted machine tool tool manufacturers to intervene in the field of robot manufacturing. Luo Baihui, head of the International Association of Mould & Hardware Plastics Industry Suppliers, believes that the demand for the world robot market is about to enter the eruption period, and China's potential huge market demand has begun to emerge. Since the unified domestic and international standards have not yet been formed, there is still a huge space for development of its core technology, and it has a natural connection with the original industry and manufacturing system, and the profit margin of the product is enormous. With the development of China's manufacturing industry, especially the development of automobile and auto parts manufacturing industry, which is the main application field of industrial robots, the assembly volume of industrial robots will increase rapidly. In addition, the industrial robot application field is gradually extending to the electronic information industry as well as construction, mining and other fields. It is expected that the average annual growth rate of industrial robots will reach about 25%. In addition, as the automated warehouse is growing at a level of 40 to 60 seats per year, the mobile robots used for logistics and handling will increase by no less than 20% per year. However, it is understood that visual positioning has become the main cause of the development of domestic robots. In most workshops or assembly lines, journalists find that the most widely used robots do not have "photoelectric eyes". Because of this, these robots can only be fixed. Do repeat simple work in one place. Since it has not been possible to find a suitable way to deal with these complexities for a long time, the field of application of robots has not been able to expand. But this situation has finally changed. One of the most powerful technologies is the two-dimensional vision system. Reference can be made to the robots developed by Fanuc CNC Systems of Japan, which use the vision system to assist the robot to pick up the components placed in the cabinets separated by several layers of standard slip sheets. This is a common method of transferring parts from one shop to another or even in the same shop. If there is no vision system, the manufacturer must use relatively expensive shaped plastic dunnage or other methods to accurately pick up the parts inside the box. This shaped plastic dunnage is relatively more expensive, and it takes between $60,000 and $100,000 for the design and manufacture of the mold. Another benefit of the vision system for robot use is the reduced cost of the robotic conveyor. Before using the vision system, many components must be positioned on a fixed pallet that is transported by the pallet conveyor. Even simple pallet conveyors are not costly, and the cost increases as the conveyor distance increases. Since the user's requirements for machine tool builders are now more than just the provision of machine tools, machine tool companies often have to provide a complete solution for the user, or the entire production line. Therefore, the involvement of machine tool manufacturers in the production of industrial robots can be said to be a matter of course. In terms of market development, we only add a new product variety to the already mature market. In fact, robots are also very useful for the machine tool industry itself. For example, the traditional process of the machine tool industry, scraping, is the long-term dependence on skilled technicians, and this work is not only time-consuming but also labor-intensive. If the robot's visual problems are solved and widely used, it is probably a good fit for this task. It seems that the development of robot technology is not only the actual needs of machine tool users, but also the function of back-feeding for machine tool manufacturing.
