The production level of China's machine tool industry, in the early 1980s, still stayed at a stage where the gap with foreign countries was large. This gap was not reduced until 2000. In 2004, 185 sets of Shenyang Machine Tool Production and Processing Center realized an output value of 210.71 million yuan. It has overcome 8 key technologies of industrialization of processing centers and realized 4 technological innovation points. The application of key technologies in a variety of machine tool products has improved the quality and reliability of the products and shortened the gap with machine tools in developed countries. The products entered the automobile, military, information and other industries in batches, blocking imports and saving a lot of foreign exchange for the country. Not only has it changed the way that the equipment needed in some areas of China has been imported, but now the products of independent innovation not only occupy the domestic market, but also start to advance to foreign markets.
Realize the industrialization of large and medium-sized machining centers
All along, China's machine tool industry exports mostly to ordinary machine tools, CNC machine tools account for a small part, with the innovation of technology has never been a glimpse
Li Xiankai said that in the 1990s, Shenyang Machine Tool had introduced many machine tools from Germany, the United States, and Japan to localization. However, because the technology transferred to us from abroad is the second-three-stream technology, and the gap between the manufacturing process conditions at home and abroad at that time, the batch of CNC machine tools that have been introduced and digested and re-absorbed have their own intellectual property rights, but the customers have purchased Then found that it is not very easy to use. “The domestic machine tool industry is inherently fragile, coupled with the widespread disapproval of manufacturers. Therefore, during the period from 1993 to 2000, China’s CNC machine tools experienced a very difficult development process, and the market itself was in a downturn, coupled with technology. Not very mature, many companies and potential customers are using imported equipment.
In 2004, through the research and implementation of the 863 project, the machine tool industry has achieved healthy and rapid development. The advancement of technology and the innovation of products are not things that are imaginary and easy to achieve. It is a long way to go to thoroughly improve the pressure on foreign companies in the machine tool industry for domestic enterprises. This is mainly due to the fact that China's basic supporting industries have been improved but still weak, unable to adapt to meet the development needs of China's current machine tool industry. Therefore, improve and improve the relevant supporting capabilities of electric spindles, CNC systems, electronic technology and other machine tools. It is the cornerstone for further industrialization and market.
The organization and implementation of the 863 research project has played a positive role in stimulating the original driving force of product innovation and technological innovation. This kind of pulling action is the investment of technological innovation for the main enterprises of innovation. This kind of investment has finally achieved obvious technological progress and upgrading of the enterprise, which has promoted the rapid development of the enterprise.
After China's accession to the WTO, the competition in the CNC machine tool industry has intensified. The competition is not only from the domestic industry, but also from the pressure of foreign manufacturers. From the perspective of all aspects of the market, the demand for machine tools is not decreasing, and the demand for high-precision, high-efficiency and high-speed machining centers is still growing. Faced with such a situation, we have taken targeted measures to achieve high-speed growth at a higher starting point based on new changes in market demand. In 2004, the total industrial output value was 680 million yuan, including 185 sets of CNC machine tools, with an output value of 260 million yuan. In 2005, the total industrial output value was 924 million yuan, and the output of CNC machine tools was 350 units.
In 2004, the key users of the machine tool industry were mainly the automobile industry, the military industry, and the private enterprise industry mold industry. Among them, the automobile and machinery manufacturing industry developed most rapidly. In the next few years, the above three industries will continue. Maintaining the momentum of growth, but with the development of various industries, its requirements for machine tool products will also change accordingly, and the demand for specialized and versatile machine tools will increase. For future market changes, Shenyang Machine Tools has been adjusted in time. The variety of CNC lathes, for the key automotive, aerospace, military and other requirements, according to user needs, developed a large and medium-sized machining center for production and design. CNC machining centers will mainly serve the mold industry and other industries.
Innovate around speed, accuracy and reliability
The industry insiders of the machine tool industry know that the current spindle speed is higher and higher, and the high speed is becoming a symbol to measure the level of a product. It has become the focus of competition, whoever adopts a higher speed. The main axis, who has a hard card in the fierce competition. The electric spindle is a standard part of the machine tool like a linear guide.
During the implementation of the 863 project, Shenyang Machine Tool launched research and innovation on the three goals of speed, precision and reliability for high-speed spindles and transmission systems, high-speed electric spindles and other application technologies, and finally solved the key technologies of 17 CNC machine tools industrialization. The bottleneck that restricts the development of industrialization.
Before the project was implemented, the rapid feed rate of Shenyang Machine Tool Production and Processing Center was 24m/min, and the newly designed THS6550X50 horizontal machining center has a three-way coordinate fast feed rate of 40m/min and a cutting feed rate of 20m. /min. The three-way coordinate rapid feed rate of 40m/min-80m/min with the horizontal machining center produced by foreign advanced countries shortens the gap. At the same time, for high-speed machine tools, the main factor affecting the positioning accuracy is the increase in the amount of heat generated by the high-speed rotation of the lead screw, which in turn causes the temperature to rise. In order to reduce the heat generated by high-speed rotation, the research group chose to lubricate the guide rail with lubricating oil.
TH57200X400 Longmen Five-face Machining Center is developed by Shenyang Machine Tool Plant based on the mature design and manufacture of gantry vertical CNC milling and boring machine. It is developed by introducing, digesting and absorbing foreign gantry five-face processing technology. . On the machine tool, the parts can be processed in one setup without the installation of the bottom surface, ensuring the machining accuracy and positional accuracy between the hole faces of the machined parts, and processing key parts such as the bed. Ideal equipment for columns, cabinets and machining precision requiring more precise parts.
As a self-designed gantry five-face machining center, TH57200X400 not only guarantees the realization of various performances of machine tools, but also has made great achievements in controlling the cost of machine tools. In particular, the design and manufacture of machine tools has greatly reduced the cost of machine tools. Save a lot of money for users. The high rigidity and heavy cutting function of the machine tool set a good example for the gantry machining center to improve the processing capacity and expand the sales market, making the machine tool more economical and practical, and creating value for the user to a greater extent.

“This 863 program is not aimed at any special industry, but for production scale and application services.†In Li Xiankai, the first machine tool factory in Shenyang, the field of CNC machine tools covers most of the country's industries. The topic of "high-speed machining center research and application" is to achieve the industrialization of mid-range machining centers and some large-scale machining centers. According to him, at that time, due to the needs of industrial development, the state proposed the requirements for the industrialization of CNC machine tools. In 2004, when the state proposed the 863 project, the technical foundation of Shenyang Machine Tool was relatively solid, and there were many explorations in this area.
