New energy equipment industry promotes rapid growth of machine tool industry
With the enhancement of product and industrial structure adjustment of China's machine tool industry, the proportion of CNC machine tools and high-end machine tools has increased significantly, and the proportion of low-end products has continued to decrease. At present, the localization rate of machine tool industry has increased to 70%. Luo Baihui, executive secretary of the International Association of Mould & Hardware Plastics Industry Suppliers, believes that while the machine tool industry is growing at a high speed, further accelerating industry and product structure adjustment and promoting industrial upgrading is still the primary and urgent task of China's machine tool industry. New energy equipment industry promotes rapid growth of machine tool industry In 2009, China became the world's largest machine tool manufacturer for the first time. However, China's domestic demand for high-end CNC machine tools mainly relies on imports. The CNC systems and functional components needed to develop medium and high-end CNC machine tools mainly come from overseas. In October 2010, the State Council issued the "Decision of Accelerating the Cultivation and Development of Strategic Emerging Industries", pointing out that it is actively developing intelligent manufacturing equipment centered on digital, flexible and system integration technologies, among which high-end CNC machine tools are the top priority. . During the entire “Twelfth Five-Year Plan†period, the development of high-end equipment manufacturing will greatly promote the rapid growth of the machine tool industry. Taking heavy-duty machine tools as an example, although after years of technological transformation and independent research and development of the products, both the production capacity and the technical level of the products have made great progress, but there are still great deficiencies compared with foreign products. The biggest gap is reflected in the technical level and operating speed of the core operating components, product accuracy retention, machine tool reliability, and overall machine tool manufacturing process level and quality. Reliability is a key indicator of the quality of high-end heavy-duty machines. At present, the average trouble-free working time of domestic CNC heavy-duty machine tools is about 300 hours, while the imported high-end heavy-duty machine tools have an average trouble-free working time of more than 2000 hours. In addition to traditional power generation and petrochemical equipment, new energy equipment such as wind power and nuclear power are also becoming a major driving force for rapid growth and technological progress in the machine tool industry. According to Luo Baihui, "The processing of new energy equipment will become the main force of machine tool demand, which requires a variety of precision, large-scale CNC, special machine tools and supporting. Advanced equipment manufacturing technology, especially advanced machine tool equipment is the new energy equipment manufacturing industry. The basic guarantee of the upgrade.†Wind power experts said that the overall design and load calculation capability of large wind turbines is poor, the design and production capacity of control systems, generators, gearboxes and bearings are poor, and the bearings and control systems of the wind turbines are still Need to import from abroad. Although China's wind power equipment manufacturing industry is developing at a fast pace, there are not many enterprises that have core technologies, and key components are basically dependent on imports. The key to restricting its improvement is that domestic manufacturing processes and processing equipment are relatively backward. Nuclear power equipment manufacturing is also facing a similar situation. According to reports, a nuclear power plant requires more than 200 pumps of various types. The main pump is a key component located in the heart of the nuclear island. It is the key to the nuclear power operation to control the water cycle. Although the structure of the nuclear island main pump is not more complicated than other pumps, it is extremely demanding and must have absolute reliability. The processing of the main pump pressure parts and functional parts requires high-precision and reliable machine tools. It is precisely because there is no corresponding machine tool processing equipment, the nuclear island main pump has long been subject to people. In addition, the production of million kilowatt-scale nuclear power plant pressure vessels, etc., requires 10,000 tons of press forging. Subsequent cutting operations require processing equipment such as ultra-heavy-duty CNC vertical lathes, super-heavy-duty CNC horizontal lathes, and large mast multi-axis linkage CNC boring and milling machines. These workpieces are expensive and have no spare parts, requiring a 100% yield, so there is a high demand for reliability and stability of the machine. At present, industry leaders have realized that energy equipment, especially new energy equipment, is a gold mine, and has begun to actively develop related machine tools. The XKD2755×570-2M CNC fixed beam double gantry mobile boring and milling machine independently developed by Wuzhong is suitable for the processing of large-sized parts such as wind power gears; the world's largest heavy-duty TK6932 CNC double-column floor milling boring machine independently developed by Qi Er Machine Tool is a large hydropower unit. The processing of super-large workpieces for nuclear power plant equipment provided key processing machine tools; the first domestic solar-powered fully automatic silicon wafer multi-wire slicer was also successfully developed. China, Japan and Germany's machine tool giants promote industrial upgrading on April 20, the world's three major machine tool companies - Shenyang Machine Tool, Japan Mori Seiki, Germany Gitemai jointly announced the news, the three parties reached a cooperation, set up a joint venture in Shenyang, targeting the world The machine tool industry changes and the need for China's machine tool upgrades. The joint venture mainly develops new machine tool products for the high-end demand of the market and jointly promotes the upgrading of the machine tool industry. This is the first cooperation of the world's three well-known machine tools, the precision machining centers produced are high-end machine tools, mainly to meet the processing needs of home electronics and automotive precision parts. The tripartite cooperation of well-known enterprises in the world machine tool industry will accelerate the pace of Shenyang to build a world-class advanced equipment manufacturing base.
