Under the guidance of the State's correct policies and policies, China's machine tool industry has experienced economic recovery and the 10th Five-Year Plan period, especially the arduous efforts of the 30 years of reform and opening up, and has established a larger scale and more complete system, laying a favorable technology. Basic, with considerable competitive strength. I. Achievements of China's machine tool industry 1. Strong machine tool throughput In recent years, with the rapid development of China's national economy and the strengthening of national defense construction, the national equipment manufacturing industry has put a lot of urgency on the basic and strategic manufacturing methods of machine tools. Demand. In 2002, the consumption of China's machine tool market rose to 5.9 billion US dollars, ranking first in the world. To a certain extent, China's machine tool industry has an extraordinary ability in terms of total supply. Reviewing the historical situation of the supply of basic equipment in China's machinery manufacturing industry, according to the national industrial census data, the updated machine tool ownership in the past 50 years is about 3.78 million units, including 2.94 million sets of gold cutting machines and 840,000 sets of forging machines. China's self-supplied equipment accounts for the majority; including heavy-duty super-heavy metal cutting machine tools and forging equipment, high-precision precision machine tools and CNC machine tools, thousands of automatic semi-automatic production lines. 2. Variety of product varieties With the development of science and technology and the improvement of people's living standards, the manufacturing industry is facing the acceleration of the frequency of manufacturing objects and the individualization of processing objects. Therefore, the machine tool industry that provides processing and manufacturing equipment is also required to produce products. Diversification, which has become an important indicator of the comprehensive strength of the machine tool industry in a country. In recent years, China's machine tool industry has been driven by market demand. The whole industry has made every effort to research and develop new products. In recent years, it has developed more than 400 kinds of independent copyright new products. By the end of 2002, the nationally updated machine tool varieties have been available for nearly 3,500. In particular, there are 1,500 kinds of CNC and other high-tech products, which are among the best in the world. China's forging equipment, electrical processing and other special processing equipment, gear processing equipment can be said to have a full range, superior performance and distinctive features. The representative products of forging machinery are: Jinan No.2 Machine Tool Factory has been in the international advanced series of series of mechanical presses, the pressure tonnage has been expanded from 20000kn to 63000kn, which is an international frontier, and has provided seven stampings for General Motors. The automatic line caused strong repercussions in the US market; Shanghai Forging Machine Tool Plant developed a hydraulic machine with a weight of 860t, a 12m automobile girders and a pressure tonnage of 50,000kn. It has the same level in foreign companies. The three-day home; Tianshui Forging Machine Tool Factory is a large-diameter steel pipe production line developed by West-East Gas Transmission Co., Ltd. and the 30000kn14m CNC hydraulic bending machine and 20000kn hydraulic pipe-making machine provided by the West-East Power Transmission Co., Ltd., which are also one of the few in the world. China's electric processing machine tools are self-contained and complete, and have formed an annual output of 20,000 units, and CNC products account for 80% of the published statistics. This number is juxtaposed with CNC metal cutting machine tools. Production capacity; technically extended to the National Invention Award for Micro EDM, CNC high-efficiency EDM milling for aero-engine integrated impeller machining, electric melting and explosion processing of super-hard material rolls, EDM cold-rolling roll processing, etc. Technical field. 3. CNC machine tools become popular CNC machine tools are the mainstream equipment of the contemporary machinery manufacturing industry, and are hot commodities in the market. Some high-end CNC machine tools are still regarded as strategic materials in the international market subject to embargo restrictions. The development of CNC machine tools in China has experienced 30 years of ups and downs and has entered a mature period from the growth stage. China's 1,500 kinds of CNC machine tools available for the market cover ultra-heavy machine tools, high-precision machine tools, special processing machines, forging equipment, cutting-edge high-tech machine tools, etc., and the fields are wide, and can be driven by Japan, Germany, Italy and the United States. 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. 4. The contribution of the R&D system The product R&D strength of China's machine tool industry consists of three parts, namely, the R&D base of the enterprise, the research department of the higher education institutions, and the research institutes of the seven institutes. The nature of the former two is developed with the foreign machine tool industry. The country is similar, and the latter is only similar to the approach taken by individual countries and regions. The research and development strength of these three aspects contributes to the technological progress of China's machine tool industry from different angles. 1. There are many examples of the company's R&D bases making achievements for product innovation and performance upgrade: 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.
