The rolling function components include the ball screw pair and the rolling guide pair. It has characteristics such as small frictional resistance, flexible drive, high speed, high rigidity, etc. It is an indispensable part for the development of the equipment industry and for the improvement of national defense and national economic strength. . Although the steel balls are small, the application of rolling functional components in the industrial economy is too numerous to mention. As long as a powerful transmission, the rolling of functional components can play an active role. It can be said that the economical development of rolling functional components is an indispensable "ball" that technically reduces friction. In the new round of development of the national economy, CNC machine tools are one of the most popular equipment on the market. From a certain perspective, CNC machine tools include mainframes, CNC systems, rolling features, and mechanical foundations. In the case of parts, the numerical control system is the brain and the nervous system, and the rolling functional parts are blood vessels. Therefore, the rolling functional parts are the key basic components of the numerical control machine tools. According to the statistics of the China Machine Tool Industry Information and Rolling Components Industry Association, the application of rolling elements in the domestic machine tool industry, in 2002, the total demand was 400 million yuan, of which about 300 million yuan was domestically produced and about 100 million yuan was imported. In 2003, The total demand will be over 500 million yuan. According to the national "fifteen" industrial plan, the average annual growth rate is 15%. By 2006, the total domestic demand for rolling elements will be more than 1 billion yuan. In fact, rolling features and CNC machine tools complement each other. An indispensable condition for the development of rolling functional components is the improvement of their own equipment capabilities. The high-tech level of equipment, the degree of numerical control, and the advanced nature of the process directly affect rolling elements. The level of production and efficiency. The level of manufacturing of rolling features cannot be separated from the application of CNC molding processing technology and the breakthrough of advanced technology. In a word, selling salt can not be drunk, and improving the equipment level of rolling functional components manufacturing industry is a top priority for our industry. In addition, the rolling functional component industry should improve its ability to respond quickly and provide more high-tech products to the market, with particular emphasis on the application of computer technology. Computer technology and information technology have brought significant economic benefits in terms of shortening new product development and production cycles, increasing resource utilization, reducing costs, and enhancing market resilience. Based on the existing network and CAD/CAM applications, we will focus on establishing an ERP information management system, strengthening enterprise information construction, and finally implementing a manufacturing manufacturing management system and a quality control assurance system with computer application as the core and advanced technology as the leading factor. . The spring-water-heating prophet scrolling function is a high-tech product with high technology intensity. Along with the development direction of high-precision, high-speed, and environmental-friendly CNC machine tools, the task of research and development of rolling-function components at this stage is: high speed, high precision, and high rigidity. . In terms of speed, the demand for rolling elements with a line speed of 40~60m/min is increasing, and the linear speed of domestic products is 20m/min. The focus of the next phase of development is high-speed rolling linear guides with a moving speed of 80m/min. For rolling element products, high precision is an eternal pursuit goal. At present, the accuracy of domestic ball screws can reach P1, meeting the needs of most domestic precision machining centers, EDM machines, and WEDM users. ; In the high-precision rolling linear guide auxiliary processing, can basically guarantee the product of high precision and high speed stability and consistency, can supply 2 precision rolling linear guide rails. However, compared with the advanced level in foreign countries, the accuracy level differs by one grade, especially the large rolling element gap of more than 3m. To make large rolling features, we must shorten the gap with the international advanced level as soon as possible. Efforts to adopt new technologies, new processes and new materials, in the processing of rolling functional components, currently, an advanced process is adopted internationally, that is, the original grinding mill manufacturing is changed to rolling and rotary milling, and the process is improved. The biggest advantage is that the medium ball deviation of the processed ball screw has small deviation, high precision, and high production efficiency. At the same time, due to complete dry cutting, the surface finish of the workpiece reaches the grinding effect, laying the foundation for improving the precision grade of the large ball screw. I wondered if the water had been used on the two-foot machine tool tool online. Who would like to expand the feature industry? Zhang Jianping, director of Nanjing Technology Equipment Manufacturing Plant of the vanguard company, said that our factory has such self-confidence, mainly because we have this foundation and have the ability to self-arm. First, there is a foundation. The process equipment factory is the first company in China to develop and manufacture rolling functional components. After nearly 50 years of development, it now possesses domestic first-rate rolling element production and testing equipment, product comprehensive design and development capabilities, production scale, and production varieties. The quality level ranks first in the domestic industry, and the domestic market share of ball screws reaches 50%, and the domestic product satisfaction rate is over 85%. The second is conditional. During the "Seventh Five-Year Plan" and "Eighth Five-Year Plan" period, the company implemented key technological transformation and scientific and technological projects, invested a total of 30 million yuan to implement technological transformation, introduced and added more than 50 processing equipment, and made the factory's product level catch up The international level. On the basis of digesting and absorbing advanced technologies, we have formed the capability for self-development. The company complies with the international technological development trend, develops in the direction of precision, large-scale, and high-speed, and has successfully developed high-speed ball screw precision rolling element products with a line speed of 36m/min. The third is the direction. To catch up with the world's advanced level, companies need to upgrade their technological level and technical quality, improve product quality, and reduce product costs. To this end, the process equipment factory is preparing for a new technological transformation, introducing advanced rotary milling machine tools, double grinding wheel guide forming grinding machine tools, sharpeners and other key equipment, breaking through the traditional process means to improve the diameter of the part taper, improve Production efficiency, improve the level of industrialization. Only when the water is out of the water can it be known that the two-footed mud is bigger and stronger. The rolling functional component industry is the need of industrial economic development. It is driven by numerical control technology and depends on the country's attention and support to the industry. Under the joint efforts of the machine tool industry, aiming at the direction, speeding up adjustment, and cooperating with each other, we will be able to realize the high-precision, high-quality, high-performance, and industrialization of rolling functional components as soon as possible, so that the rolling functional component industry in China will become an industrial economic development.
