Breaking the monopoly to replace imports
On April 22nd, the special CNC grinding machine for high-speed railway track plates independently developed and put into production by Sichuan Yibin Push Drive Co., Ltd. passed the joint inspection and acceptance of the Ministry of Railways and the China Railway Sixth Bureau. It is reported that the successful development and commissioning of the equipment has broken the long-term monopoly of China's high-speed railway special-purpose CNC grinding machine market.
In fact, before this, Huadong CNC also successfully developed a special CNC gantry grinder for the wheel-rail high-speed railway Borg board bearing platform.
Another example is that Nanjing Sikai Electronic Enterprise Co., Ltd. and Tsinghua University have jointly developed a five-axis linkage laser processing machine tool to break the foreign technology blockade and solve the core technical problems in high-precision radar manufacturing. The machine tool was unveiled at the 2009 China Industry Fair in Shanghai.
“It has a processing accuracy of μ, which is equivalent to 1/70 of the hair. Its biggest highlight is the five-axis linkage CNC and fiber laser.†According to the company's technicians, this machine with a cash register size can also process Medical devices such as cardiac stents with extremely high precision requirements can be used in aerospace, medical and other fields.
In the development of high-precision radar, a core micro-device is needed - a spherical grid with a diameter of only 12 mm, which is made of metal molybdenum, and 72 trapezoidal grids in the grid. The "ribs" connected between the small grids are only 0.12. Millimeter.
Don't underestimate this insignificant 12mm. Since the melting point of molybdenum is as high as 2000 °C, there is no processing equipment in China, and foreign technology is blocked. The processing technology of spherical grid has always been the bottleneck restricting the improvement of high-end products in China.
At the China CNC Machine Tool Exhibition held in Nanjing this year, Jinan No. 2 Machine Tool Group participated in the newly developed moving beam gantry milling and milling center. It is reported that the major equipment has reached the world's advanced level in terms of technical performance, automation, processing accuracy, etc., breaking the foreign technology and price monopoly in one fell swoop, making localization a reality.
"Don't look at it's 4 meters high and weigh 200 tons, but the big ones are very fine and flexible. The machining accuracy is locked within the error range of 8 microns, which is equivalent to one tenth of the hair." The exhibitors of the second machine introduced the reporter. This machining center also realizes one-time clamping and five-face processing of the workpiece, and the production efficiency is greatly improved. The price is only two-thirds of the similar imported equipment in foreign countries.
It is understood that with a focus on breaking the technological monopoly of foreign countries, Jinan No. 2 Machine Tool has continuously strengthened the independent research and development of core technologies in recent years, and achieved breakthroughs in areas such as upgrading product automation, numerical control level and special machine development, and replacing key equipment with imports. The high-tech products of intellectual property are widely used in key areas of national economy such as energy, aviation, aerospace, weapons, ships, automobiles and railways.
"Compared with developed countries, we are accelerating to catch up. Some products have been successfully developed and even let foreign counterparts start to panic, not only breaking their long-term monopoly in the domestic market, but also forcing them to lower the price of their products." Wu Bolin, executive vice president of the Industrial Association, said.
Enhance the strength of the company through product innovation
Wu Bolin said that at the China CNC machine tool exhibition, a number of high-speed horizontal machining centers, five-axis linkage precision electric forming machine tools, precision CNC one-way wire-cutting machines with automatic threading devices, and CNC winding machines appeared. Double swing angle CNC universal milling head and other independent innovative products, CNC, precision, high-speed, flexible, composite and other high-end products are dazzling, product specifications from small, medium, large to heavy and super heavy, but also have everything.
He believes that these products represent the latest technological development direction of contemporary machine tool products, and also reflect the progress made by China's machine tool manufacturing in product structure adjustment.
In fact, in order to adapt to changes in market demand since the financial crisis, many companies have reduced the production of low-end, common products, accelerated the pace of upgrading of economical CNC machine tools, and focused on the development of high-end CNC machine tools and production lines. Through technological innovation and the launch of a number of new products, major enterprises have made great progress in product structure adjustment. In 2009, the numerical control rate of machine tool output value of key enterprises in the industry reached more than 50%, an increase of 5% year-on-year.
At the same time, the machine tool industry has also emerged as a group of companies that have emerged in the international market. For example, Jinan Second Machine Tool Group Co., Ltd. mentioned above has won key projects such as 5,000-ton multi-station presses and 3,200 tons of large-scale press lines from customers in the United States, Australia, Brazil, etc., and established a competitive position in the international market. The global suppliers of Ford, Mercedes-Benz and other international auto manufacturers have been praised by foreign customers as one of the "World's Three Major Stamping Equipment Manufacturers".
Beijing No. 1 Machine Tool Plant, which specializes in the development of heavy-duty CNC machine tools, has successfully upgraded its capabilities in the development and manufacture of heavy-duty machine tools after successfully acquiring the world's leading heavy-duty machine tool company, Adolf Waldrich Coburg Machine Tool Company. At present, Beijing No. 1 Machine Tool Plant closely combines the urgent needs of domestic large-scale power, aerospace and heavy machinery users for ultra-heavy heavy-duty five-axis linkage composite machine tools, and has developed the world's largest CNC bridge gantry five-axis linkage car with a gantry width of 10 meters. The milling and compounding machine tool can complete the processing of key parts of nuclear islands of large nuclear power plants, and break through the key process technologies such as three-stage beam assembly processing technology in the research and development process.
Wuhan Heavy Duty Machine Tool Group Co., Ltd. is the world's largest ultra-heavy horizontal lathe lathe with a diameter of 5 meters and a load of 500 tons. It can be used for rotor processing of 1.1 million kilowatt nuclear power half-speed rotor and 700,000 kilowatt water turbine. . During the development of this machine tool, it broke through the key core technologies such as ultra-heavy-duty high-precision static pressure spindle technology, which made the machine tool performance reach the international advanced level. In the manufacture of heavy-duty vertical lathes, Wuzhong has become a leading company in the world.
Wu Bolin said that 2009 is the most prominent year for China's product structure adjustment in the past decade. There are many products with high gold content, high grades and high technical complexity, and the product structure changes greatly.
The adjustment of product structure can enhance the confidence of the industry's sustainable development. Wu Bolin believes that the machine tool industry can have such a good performance in 2009. Objectively speaking, it is the light of the financial crisis. But subjectively speaking, because the development of machine tool products must have a certain period of time, if it is not the first 3 to 5 years to start development, there is no such situation. Product structure adjustment is not a one-off event. When the industry has achieved rapid development for the past 8 consecutive years, many people in the industry have not neglected the research of basic technologies and the development of new products, which allows us to develop the future of the industry. Full of confidence.
In recent years, a series of national policies, including the implementation of major projects and the current situation in the industry, have made us more aware of the importance of technology development. Of course, major projects can only be drug introductions. More is that enterprises have seized the rare opportunity of international economic restructuring, clarified the main direction, and accelerated structural adjustment and industrial upgrading.
