We must face up to the gap between China's machine tools and functional components and the international level.
November 25 05:00:07, 2024
China's high-end CNC machine tools and key functional components industry can not meet domestic needs. Since 2009, China has become the world's largest machine tool manufacturing company for three consecutive years. The machine tool is the "mother of industry". The industrial level looks at the equipment manufacturing industry. The level of equipment manufacturing industry looks at machine tools, and the machine tool industry is not forced to raise the overall level of China's industry. At a time when China is making efforts to promote the adjustment of economic structure and the development mode, the demand for high-end CNC machine tools, high-efficiency tools and precision measuring instruments is large and dependent on key areas and key projects. It can be found that this large but not strong situation has entered a stage of breakthrough. The "mother of industry" restricted the aviation industry to officially launched the large aircraft project in 2008. At present, the prototype C919 of the large aircraft project has been successfully developed. It is expected that the C919 will achieve its first flight in 2014, and the airworthiness certificate will be obtained and put on the market in 2016. The requirements of the aviation industry for machine tools cover almost all the achievements of modern machine tools, including high-speed, precision, high-efficiency, composite CNC machine tools, five-axis machining centers and other key manufacturing equipment, as well as modern and efficient tools. China is one of the world's largest shipbuilding countries. The modern shipbuilding industry is also inseparable from large-scale high-end machine tools, such as heavy-duty and super-heavy gantry boring and milling machines, CNC floor boring and milling machines, five-axis linkage CNC boring and milling machines, crankshaft turning and milling centers, and large crankshaft grinders. A large number of high-end large-duty CNC machine tools. China has developed into the world's largest auto producer and the world's largest auto consumer market. The automotive industry has always been the most important user in the machine tool industry. Automobile manufacturing has the characteristics of mass production and requires a large number of high-speed, high-efficiency, high-reliability CNC machine tools. Energy shortages have always been a bottleneck restricting China's national economic development. To this end, China's power industry will implement a diversified energy supply strategy. The development of the power industry requires a large number of high-reliability, large-size, high-rigidity CNC machine tools, such as heavy-duty CNC gantry boring and milling machines, heavy-duty CNC floor boring and milling machines, heavy-duty vertical lathes, blade processing machines, and leaf root groove special processing machines. Agricultural machinery, engineering machinery, textile machinery, railway transportation and other industries are inseparable from the increasingly high-end demand for machine tool products in the process of adjusting structure, transforming development mode and carrying out industrial upgrading and technological transformation. The 5% problem comes from the industry statistics of China Machine Tool Association in 2011. The import of machine tool products in China is growing rapidly, with imports of 20.3 billion US dollars, up 29% year-on-year. Imports are all medium and high-grade machine tools. "Because of the changes in the international machine tool marketing strategy, high-tech-led, low-priced mid-range machine tool products armed with high technology quickly occupied China's machine tool market, posing serious challenges for China's domestic machine tool enterprises." Guan Xiyou, chairman of Shenyang Machine Tool Group. In the machine tool industry, CNC machine tools are generally based on the number of axes, below the three axes is low, three to five axes are medium to high, and five or more are high. For the industry, the difference between the traditional and modern production equipment is the traditional machine tool and CNC machine tool, which has become the industry consensus. Machine bed machine intelligent and automatic CNC machine tools are the direction of the machine tool industry. Its high precision, high precision, high speed, flexibility and intelligence are the hallmarks of modern industry. The modern equipment industry is developing towards extreme manufacturing. One is getting bigger and bigger, the other is getting smaller and smaller, the third is more and more complicated, and the production process is highly integrated. The level of equipment manufacturing industry is in the northeast, the level of machine tools is also in the northeast, and the northeast is the region with the most concentrated and strongest machine tool enterprises in China. The three major enterprises in the Northeast Machine Tool Group, such as Shenyang Machine Tool Group Co., Dalian Machine Tool Group Co., Ltd. and Qizhong CNC Equipment Co., Ltd., understand that the main disadvantages of the machine tool industry are: First, the accuracy, stability, reliability and other gaps . For example, the five-axis linkage CNC machine tool has no faults for 1500 hours, and the domestic production is about 1000 hours, a difference of 1/3. Second, the composite performance of machine tools is quite different. At present, the five-axis linkage machining center on the market is mostly used for aerospace, nuclear power, etc., and the price of a single unit is four to five million yuan. The five-axis linkage CNC is a technology controlled by Europe and is the core technology in the core technology. It is strictly forbidden to leak in Europe. The five axes must be guaranteed not to be used in the military before they can be introduced. Shenyang machine tools, Dalian machine tools, and Qizhong CNC can do three-axis, five-axis can also be done, but the performance has a certain gap compared with imported products. The high-end machine tools used by domestic enterprises and aerospace and other important scientific research units are all imported. Third, the gap in the CNC system. CNC system is the core of CNC machine tools. Germany's Siemens, Liebherr and Japan's Mazak and Farak control the highest level of CNC system. The price of 16 software packages of Liebherr CNC system is close to the price of the parent machine. The software is together with the parent machine. Selling, not selling separately, the software profits are very high. At present, the numerical control systems of medium and high-end machine tools used by domestic machine tool enterprises are basically imported from abroad. Fourth, the gap between other key features. Jiang Huaisheng, vice president of Dalian Machine Tool, said that Dalian machine tools can match 95% of the international advanced level, but the remaining 5% is not a business or even an industry, including steel raw materials, standard parts, screws, nuts, etc. Improve the overall level of national industry. In addition, the process, testing and other aspects are currently not reaching the world's advanced level. "To attack the CNC system like two bombs and one star and high-speed rail" comprehensive analysis of the current basic characteristics of the industry, major contradictions and significant changes in the domestic market in the near future, we can easily judge that the machine tool industry is in a key turning point to achieve major strategic changes. period. First of all, from the perspective of national development strategies, high-end machine tool products are heavily dependent on imports, which is related to national defense and economic security. Secondly, strategic transformation has become an inevitable choice for the survival and development of the industry. In recent years, the development of industrial enterprises has laid a solid industrial foundation for the implementation of the strategic transformation from large to strong. It can be said that from big to strong has become the common aspiration and inevitable choice of the industry. The China Machine Tool Industry Association, as early as in October 2011, held the sixth meeting of the executive director (expansion) meeting, and passed the "Working Keys during the Twelfth Five-Year Plan Period of the Machine Tool Industry" (Trial). As one of the key tasks of the industry's “Twelfth Five-Year Planâ€, it is one of the key tasks of the “Twelfth Five-Year Plan†of the industry; it clearly puts forward the three major landmarks of the industry during the “Twelfth Five-Year Plan†period: First, it is a key industry. Breakthrough progress in providing equipment and services in the core manufacturing field; second, the domestic market share of medium and high-end CNC machine tools has increased significantly, and the domestic market share of medium and high-end CNC systems and functional components has increased significantly; thirdly, some world-renowned brands and advantageous enterprises have been formed. . Some entrepreneurs and experts in the machine tool industry suggest: lay the foundation work and focus on solving all kinds of machine, electricity, liquid, gas, optical components and functional components, NC systems, tools, measuring, accessories, etc. And its functional support; focus on improving and improving the processing technology, machine tool accuracy, efficiency, automation, reliability, stability, durability, etc.; attach great importance to the CNC system, increase the original innovation input of the CNC system. It is understood that Japan's Farak Company has invested about 2 billion yuan every year and has been investing for more than 20 years. CNC machine tools are the "two bombs and one star" in the equipment manufacturing industry. They must attack the CNC system like the "two bombs and one star" and the high-speed rail, and organize dozens of professional disciplines such as electrical, mechanical, materials, motors, computers, and production processes. First-class experts, focus on strengths and strengths. Like many entrepreneurs in other industries, many entrepreneurs in the Chinese machine tool industry have a hard-working spirit of hard work. They have developed a lot of effort in years of struggle, and they are full of great pressure and full of the future. Confidence. In 2011, Shenyang Machine Tool Group achieved a sales revenue of over RMB 18 billion, ranking first in the world. This is the first time that a Chinese company has won the world's machine tool industry champion. In 2002, the company's sales revenue was only 800 million yuan. "The world's first scale is only a phased goal. In the future, Shenyang Machine Tool will also strive for the world's number one in terms of brand and management." Guan Xiyou, chairman of Shenyang Machine Tool, said.
