There is a gap between China's machine tool industry and international

Since the reform and opening up, China has constantly pursued all-round development in all aspects of technology, science and technology. Since 2009, China has become the world's largest manufacturer of machine tools for the third consecutive year, but it is also the world’s largest importer of machine tools. It can be found that such a large but not strong situation has entered a stage of breakthrough.

"The Mother of Industry" Constraints

The machine tool is the “mother of industry”. The industrial level depends on the equipment manufacturing industry, and the level of equipment manufacturing industry sees the machine tool. The machine tool industry is large and does not force the improvement of the overall level of China's industry.

While China is making great efforts to promote the adjustment of economic structure and the transformation of development methods, key areas and key projects have high demand for high-end CNC machine tools, high-efficiency tools, and precision measuring instruments.

The aviation industry officially launched a large-aircraft project in 2008. At present, the prototype of the large aircraft project, the C919, has been successfully developed. It is expected that the C919 will achieve its first flight in 2014, and the airworthiness certificate will be obtained in 2016 and put on the market.

The high 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 largest shipbuilding countries in the world. The modern shipbuilding industry is also inseparable from large-scale high-end machine tools such as heavy-duty and ultra-heavy gantry boring mills, CNC floor boring and milling machines, 5-axis CNC boring and milling machines, crankshaft turning and milling centers, and large crankshaft grinding machines. A large number of high-end heavy-duty CNC machine tools.

China has developed into the world's largest car producer and the world’s largest consumer car market. The automotive industry has always been the most important user of the machine tool industry. Auto manufacturing has the characteristics of mass production and requires a large number of high-speed, high-efficiency, and high-reliability CNC machine tools.

Energy shortage has always been a bottleneck restricting the development of China’s national economy. To this end, China's power industry will implement a diversified energy supply strategy. The development of the electric power industry requires a large number of high-reliability, large-scale, high-rigidity CNC machine tools, such as heavy-duty CNC boring mills, heavy-duty CNC boring and milling machines, heavy-duty vertical lathes, blade processing machines, and blade root processing machines.

Various industries such as agricultural machinery, engineering machinery, textile machinery, railway transportation, etc. are inseparable from the demand for more and more high-grade machine tool products in adjusting the structure, changing the development mode, and carrying out industrial upgrading and technological transformation.

5% of the puzzle

Industry statistics from the China Machine Tool Association in 2011 showed that China's imports of machine tool products grew rapidly, with imports of US$20.3 billion, a year-on-year increase of 29%. Imports are all high-grade machine tools.

“Because of the changes in international machine tool marketing strategies, the use of high technology as a precursor, and the use of high-tech armed low-priced mid-range machine tool products to quickly occupy the Chinese machine tool market, poses a serious challenge to China's domestic machine tool companies.” Guan Xiyou, chairman of Shenyang Machine Tool Group, said.

In the machine tool industry, numerical control machine tools generally use the number of axes as the standard, the three-axis or lower axis is the low-grade, the three- to five-axis are medium-to-high grade, and the five-axis or higher axis is the high grade. For industry, the distinction between traditional and modern production equipment is the traditional machine tools and CNC machine tools, which has become the industry consensus. Machine bed machine intelligent and automation that CNC machine tools is the direction of the machine tool industry, its high precision, high fineness, high speed, flexibility, intelligence, is a sign of modern industry. The modern equipment industry is developing in the direction of extreme manufacturing. One is more and more tall, the second is more and more small, the third is more and more complex, and the production process is highly integrated.

Looking at the level of equipment manufacturing industry in the northeast, the level of machine tools also looks at the northeast, and the northeast is the most concentrated and most powerful area of ​​China's machine tool companies. The reporter learned from interviews with three major companies, namely Shenyang Machine Tool Group Co., Ltd., Dalian Machine Tool Group Co., and Qizhong CNC Equipment Co., Ltd., that the main deficiencies in the machine tool industry are:

First, the accuracy, stability, reliability, and other gaps. For example, five-axis linkage CNC machine tools foreign products continuous 1500 hours without failure, made about 1000 hours, a difference of 1/3.

Second, the compounding performance of machine tools is quite different. At present, the five-axis linkage machining center is mostly used in aerospace and nuclear power, and the price of a single unit reaches four to five million yuan. Five-axis linkage CNC is a European control technology and a core technology in core technology. Europe is strictly prohibited from leaking. The five axes must be guaranteed not to be used for military purposes. Shenyang Machine Tool, Dalian Machine Tool, Qizhong CNC can do three axes, five axes can also be done, but there is a certain gap between performance and imported products. The high-end machine tools used by domestic companies, aerospace, and other key research institutes are all basically imported.

Third, the gap between CNC systems. CNC system is the core of CNC machine tools. Germany's Siemens, Liebherr and Japan's Mazak and Farak have mastered the highest level of CNC system. The Liebherr CNC system has 16 software packages whose prices are close to the price of the mother machine. The software and the parent machine together Selling, not selling separately, the software profit is very high. At present, the CNC systems used by domestic machine tool companies in the high-end machine tools are basically imported.

Third, the gap between other key components. Jiang Huaisheng, Vice President of Dalian Machine Tool Co., Ltd. stated that Dalian's machine tools can reach 95% of the international advanced level, but the remaining 5% is not a company or even an industry can do, including steel raw materials, standard parts, screws, nuts, etc. Improve the overall level of the country’s industry. In addition, the process, testing and other aspects are currently not up to the world advanced level.

"To attack the CNC system like two bullets and one high-speed train"

"Comprehensive analysis of the industry's basic characteristics at the current stage, major contradictions and significant changes in the recent domestic market, we can easily judge that the machine tool industry is at a critical turning point for major strategic changes." Wu Bolin, executive vice president of China Machine Tool Industry Association It gives its own judgment on the current industry situation.

He believes that, first of all, from the perspective of the national development strategy, high-end machine tool products are heavily dependent on the status of imports and are related to national defense and economic security. Secondly, the strategic transformation has been an inevitable choice for the survival and development of the industry. In recent years, the development of industry and enterprises has laid a solid foundation for the industry to implement a strategic change from a big change to a strong one. "It can be said that changing from big to strong has become the common aspiration and inevitable choice of the industry."

The China Machine Tool Industry Association held its sixth five-man standing director meeting (enlarged) meeting in October 2011. It adopted the work points (trial) during the "12th Five-Year Plan" period of the machine tool industry, and proposed to "enhance the promotion of high-end CNC "Assistency of systems and functional components" is one of the key tasks for the industry during the "Twelfth Five-Year Plan" period; it clearly puts forward three major goals for the industry to change from strong to strong during the "Twelfth Five-Year Plan" period: First, to manufacture core products for key industries. The field has made breakthroughs in the provision of equipment and services. Second, the domestic market share of medium-to-high-end CNC machine tools has increased significantly. The share of medium-to-high-end CNC systems and functional components in the domestic market has increased significantly. Third, several world-renowned brands and advantageous companies have formed.

Some entrepreneurs and experts in the machine tool industry suggest that we should lay a solid foundation for the various machine, electricity, liquid, gas, optical and optical components and functional components, NC systems, tools, measurement, accessories, etc. that are indispensable to machine tools. And its functional support; efforts to enhance and improve the processing technology, machine tool accuracy, efficiency, automation, reliability, stability, durability, etc.; attaches great importance to the numerical control system, increase the original CNC system investment. It is understood that Japan’s Farak has invested about 2 billion yuan each year for more than 20 years.

CNC machine tools are the “two bullets and one star” in the equipment manufacturing industry. They must attack the CNC system as high-speed rail as the “two bullets and one star” and organize dozens of professional disciplines such as electrical engineering, machinery, materials, motors, computers, and production processes. First-rate experts concentrate their strength on research. Like many entrepreneurs in other industries, many entrepreneurs in the Chinese machine tool industry have a hard-working spirit and have worked hard for many years. They feel tremendous pressure and are full of the future. Confidence.

Shenyang Machine Tool Group achieved sales revenue of RMB 18 billion in 2011, ranking first in the world. This is the first time that Chinese enterprises have become the world champion in the machine tool industry. In 2002, the company’s sales revenue was only 800 million yuan.

“The first in the world is only a phased goal. In the future, Shenyang Machine Tool Co., Ltd. must also strive for the first in the world in terms of brand and management.” said Guan Xiyou, chairman of Shenyang Machine Tool.
