Characteristic of heavy equipment in China will enter the season demand - manufacturers seal splint members
With domestic demand, driven by countries and industrial development, China's CNC machine tool show the large-scale, high speed, low noise, fast response trends. CNC gantry CNC drill floor, the large machining centers with five sides and a series of sophisticated, large-scale special equipment for the urgent need for large and heavy auxiliary functions rolling, indicating that a large, heavy rolling functional components are entering an era of demand. The face of this rare opportunity for development many domestic and foreign manufacturers are rolling features introduced for new products, and in April in Beijing CIMT2009 exposure, more half of the manufacturers have focused on running large-scale introduction, re - posting product feature set, which SK7450 10 meters with a global precision CNC thread grinder grind 10 meter precision ball screw, but also imports whirlwind eight-meter precision CNC milling milling machine out the entire 10 meter wide ball screw, but there is also the main rotating ball nut long ball screw driven, while than in large heavy duty linear bearing guide, companies have launched a national key high rigidity, the guide rollers recirculating heavy. In large differences Heavy load balancing function at home and abroad, according to the personal opinions of authors, mainly in the following areas: basic research theoretical areas: domestic manufacturers involved in the deployment of the personal characteristics of basic research was practically nonexistent. In recent years, with a sense of increased innovation, the branch of several major manufacturers, such as: Hanjiang Machine Tool Co., Ltd., Nanjing, technology, Seiko Bot, Dalian High King, and other companies to improve cooperation with universities, but only in co-operation project individually, lack of system is based on research theoretical, while universities may think is a characteristic displacement of small industry and lack of funding, are willing to work long time spent studying high-level personnel are very few. While abroad, including Germany, Japan and even Taiwan's China business, as the support of consortium, the capital adequacy, and the attention of enterprises, attracting a large number of senior researchers dedicated to basic theoretical research and development of new products. The new product development, product performance and reliability: the major internal rolling mill with a new product, compared with similar foreign products instead of just seems quite similar. The main reason is a lack of support for basic research, second is the lack testing equipment for different benchmarks. I've been abroad a function of displacement advanced manufacturing plant visit to see test equipment companies and production of a considerable amount of equipment, and the inner exception of a few major manufacturers have a limited number of test kits, most of small firms in this field is blank. Processing equipment and test equipment: national characteristics in a large roll of heavy techniques manufacturing have made great strides in recent years, several major manufacturers have produced a "column" in the name of the "accounts" High rigidity, heavy rolling straight guideway, and bulk import substitution to meet customer needs. In the manufacturing technology ball screw, China has two kinds of sophisticated production process, using a precision scale ball mill manufacturer of precision CNC screw thread the main production equipment Hanjiang Machine Tool SK7450 × 100 CNC thread grinder, Anyang Xin Sheng × 90 CNC production SK7450 thread mill and machine as the Han River, the Shanghai production machine tool CNC SK7450 × 50 thread mill, and the other is the use of hard turning CNC technology milling the formation of a court, the production of large, heavy ball screw, the main equipments are imported PW160-type cyclone PW300HP CNC milling, production 6-meter national Hanjiang Machine Tool CNC milling machine cyclone. The cost of production abroad due to other reasons, multi-use technology rotating hard milling and cold forming technology to process large screw heavy ball was rarely used in precision grinding techniques to produce a large ball screw. The cold forming process is difficult because the accuracy of the product is low, cycle, big mistake, now in the country or blank. Test equipment is now almost all domestic enterprises, Chinese manufacturing equipment, precision instrument for measuring dynamic whole. Instrument accuracy, reliability, and other indicators have reached international advanced level, to meet the needs of production, and completely replace imports but the lack of nuts, measuring instrument rail regulator and an integrated performance measurement tool, the lack of reliability testing, global performance testing, life testing and other testing equipment. Therefore, the prevalence of domestic firms lagged behind the accuracy of performance indicators Product. Direction for the Future: The National movement has the industry after 30 years of accumulation, the development has a certain base, one of the companies principals have been involved in development, and manufacturing engineering personnel and techniques, technical team of skilled workers. By introducing continuously, digesting and absorbing advanced foreign technology and production equipment and test equipment, I think the major projects through the application of science and national technology, domestic manufacturers of the key enterprises will be equipped with a more advanced level that has great tools, CNC and testing specialist equipment, and basic theoretical research, evidence-based performance, reliability, research, testing progress. Key to domestic companies this goal, all developed their own priorities, including the level of Hanjiang Machine Tool Co., Ltd. for domestic and foreign advanced levels, there were five core tasks: research Rolling basic feature. optimal design and advanced manufacturing technology research and application. testing technology and overall performance study. materials, heat treatment and modification of technical studies. precision and performance to keep the reliability of technical studies. We hope that through the implementation of major projects in these revolutionary features that make the internal material the price advantage an advantage of the brand. About the Author
