The improvement of machine tool products is a major boost to the development of the national industrial industry. At present, the machine tool market, CNC machine tools have become mainstream. After more than 30 years of development, domestic CNC machine tools have begun to enter a mature stage. The product range is complete and applicable in a wide range of fields. The breakthrough in innovation technology is the world leader in the world. The five-axis coordinate linkage CNC machine tool is one of the high-point markings of CNC machine tool technology. The five-axis linkage milling machine used for large-scale propeller space surface machining has caused a sensational US and Japan sanctions against the former Toshiba incident of the former Soviet Union. Eight years ago, the US Congress imported 16 such multi-axis aircraft for aircraft manufacturing. Linking the old machine tool and concocting the so-called Cox report requiring sanctions. CNC super heavy-duty machine tools are the key equipment for the manufacture of water, fire, nuclear power plant equipment, shipbuilding, metallurgical mines and other major equipment manufacturing and heavy weapons. The CNC vertical lathe developed by Wuhan Heavy-duty Machine Tool Group has a diameter of up to 16m. It has produced 5 sets of CNC lathes, which can represent the production capacity and level of super heavy-duty machine tools in China. The first station once met the urgent needs of users in the manufacture of the hydroelectric power plant of Yantan Hydropower Station. In the past 8 years, he has made great achievements in production and use, and he has been called "contribution equipment" by users. The latter several units continued to play an important role in the national key engineering power station equipment, and were praised by users for ensuring the completion of the processing of the 550t heavy giant turbine runner known as the world's largest Three Gorges Power Station. The super heavy-duty machine tools that have been successfully put into use include CNC floor-standing boring and milling machining centers, CNC gantry type, bridge type and fixed beam type. The compound function understands the milling machine and the workpiece weight is 300t. The horizontal lathe with a diameter of 4.5m, the CNC roll grinder with a workpiece weight of 200t and a diameter of 2200mm, there are only two or three kinds of machine tools in the world. The independent copyright varieties of China have reached the world advanced level, and China has become one of the few suppliers of super heavy-duty machine tools. Vertical horizontal machining center combines the basic functions of floor milling machine and bed milling machine, and has the characteristics of automatic tool change or automatic change of workpiece pallet according to NC program. It is also the basic equipment for flexible production line and needs to be needed in machinery manufacturing. A large amount of processing equipment accounts for about 30% of the total demand for CNC metal cutting machine tools. It is a hot commodity in the world machine tool market. China has developed rapidly in recent years, with more than 40 enterprises producing, general varieties have been mass-produced, and a few manufacturers High-precision, large-size products have entered the market. CNC lathes are also one of the largest proportions of CNC machine tools. More than 50 companies in China have produced them. Shenyang Machine Tool Group, Dalian Machine Tool Group, Jinan No. 1 Machine Tool Plant, Baoji Machine Tool Plant, Yunji, etc. have all been batched. Production, full range, stable and reliable quality, and some have crossed the threshold of monthly production of 100 units. CNC gear processing machine is also one of the strengths of China's machine tool products. It is a series of six-axis five-link CNC hobbing machine, seven-axis five-link worm-type grinding wheel grinding machine, seven-axis six-coupling spiral bevel gear grinding machine, all of which have been in the last three years. Enter the world's most advanced machine tools for mass production. China's CNC machine tools have been extended to complete sets and composite areas: Zhongjie Machine Tool Plant has completed the 7-month delivery period for the Shanghai Maglev Train Project and handed over 4 production lines with CNC boring and milling machines as the main body. An outstanding representative of equipment capabilities. The numerical control system device is the nerve center of CNC machine tools, and it is a key link that has long hindered the development of China's numerical control field. On a global scale, after years of fierce competition in the market, the survival of the fittest has formed a monopoly situation in which Japan's FANUC monopolizes 50% of the world market and Germany's Siemens accounts for 25%. Since the end of the 1990s, China has mastered the open architecture based on the general 32-bit industrial control machine, and once boarded the same starting line in the contemporary era, and developed a numerical control system that can be matched with machining centers, compound turning machines and gear machines, especially to control Five-axis linkage and CNC system with networked remote monitoring, diagnosis and operation functions, and developed NC machining of spiral bevel gears. 3D laser vision inspection, propeller seven-axis five-link machining and the world's original space surface interpolation software. At present, the domestically produced CNC system that has been put into the market in batches has the advantage of performance and price ratio, and is changing the monopoly situation in which the international strong players can live in the Chinese market. Matching digital AC servo speed control motors and spindle motors have been published with their own copyrighted products. Product research and development is the key to the upgrading of the machine tool industry. At present, the product research and development strength of China's machine tool industry consists of the research and development base of the enterprise, the research department of colleges and universities, and the institute of seven specialized institutes. The three are from different angles for the technology of China's machine tool industry. Progress contributes. 1. There are many examples of the company's R&D bases making achievements for product innovation and performance upgrades. For example, the high-efficiency CNC seven-coordinate six-coupling worm-type grinding wheel grinding machine developed by Qinchuan Machine Tool Group Technology Research Institute in 2002 has reached the world advanced level. Filling the gaps in international specifications; the high-precision super heavy-duty roll grinders developed by the National Technology Center of the Xianfeng Machine Tool Plant have been placed in the world's first. 2. The scientific research team of colleges and universities is known for its basic common technology, cutting-edge technology and software technology research. The company has developed products with complementary advantages and achieved the achievements of cutting-edge technology products such as virtual axis machine tools. The establishment of production and operation companies in colleges and universities, and the transformation of special excellent scientific research results into machine tool products may be a special way in the world's machine tool industry. The spiral bevel gear grinding machine developed by Central South University to achieve the world's advanced technology. Huazhong University of Science and Technology and other world-class rapid prototyping products have entered the market in a similar way. 3. The independent research unit in the machine tool industry has been undertaking basic common research and development work, and has the advantage of integrating and developing top-level products with a number of basic common technologies. After the reform of the scientific research system, it has the nature of science and technology-oriented enterprises, and its vitality is enhanced. The nanotechnology machine tool of Beijing Machine Tool Research Institute and the CNC rotary head stamping and laser compound machine tool of Jinan Foundry and Forging Equipment Research Institute are examples of China's R&D strength. The R&D capability is also embodied in the special milling machine for the special needs of the Shenzhou manned spacecraft combustion chamber, the ultra-high-travel vertical car for nuclear power boiler processing, and the special equipment for processing the world's largest caliber large-field astronomical telescope parts. All of them paid a satisfactory answer.
