should Actively Develop Large

With the country-driven domestic demand and industrial development, China's CNC machine tool show to the large-scale, high-speed, low noise, fast response trends. CNC gantry milling, CNC Floor Boring, large five-sided machining centers and a number of sophisticated, large-scale special equipment for the urgent need for large, heavy rolling ancillary features, which indicates that a large, heavy rolling functional components are entering a demand season.

The face of this rare opportunity for development, many domestic and foreign manufacturers are rolling features introduced corresponding new products, and in April held in Beijing CIMT2009 exhibition, more than half of the rolling feature manufacturers are focused on the introduction of large-scale, re - Scroll feature set products, both of which SK7450 10 meters with an overall precision CNC thread grinder grind of 10 meters precision ball screw, it also imports whirlwind eight-meter CNC milling machine precision milling out the whole 10 meters large ball screw, but also There ball nut rotating main long ball screw-driven, while in large heavy-load linear rolling guide, the national key enterprises have launched a high-rigidity, heavy roller linear guide.

In large heavy-load rolling feature differences at home and abroad, according to the author personal views mainly in the following areas:

Basic theoretical research areas: domestic manufacturers engaged in rolling features of basic research personnel was virtually nonexistent. In recent years, with the sense of innovation increases, the domestic several major manufacturers, such as: Hanjiang Machine Tool Co., Ltd., Nanjing, technology, Bot Seiko, Dalian High-King and other enterprises to enhance co-operation with the universities, but only on individual project co-operation, the lack of system is based on theoretical research, while universities may think that scrolling feature is a small industry and lack of funding, are willing to work long been engaged in the study very few high-level personnel. While abroad, such as Germany, Japan and even China's Taiwan's enterprises, since the consortium's support, the capital adequacy, and corporate attention, attracting a large number of high-level researchers engaged in basic theoretical research and new product development.

The new product development, product performance and reliability: the major domestic rolling plant features a new product, compared with similar foreign products instead of just looks like quite similar. The main reason there was a lack of basic research support; second is the lack of testing equipment for various performance tests. I have been abroad a scrolling feature advanced manufacturing plant visit to see test equipment and production companies a considerable amount of equipment, and domestic exception of a few major manufacturers have a limited number of test equipment, the vast majority of small businesses in this area is blank.

Processing equipment and testing equipment: domestic features in a large heavy roll manufacturing techniques have made great strides in recent years, several major manufacturers have produced a "column" on behalf of the "beads" of high rigidity, heavy rolling straight Guideway, and bulk import substitution to meet customer needs. In the ball screw manufacturing technology, China has two kinds of sophisticated production process, one uses a large-scale precision CNC grinder manufacturer of precision ball screw thread, the main production equipment Hanjiang Machine Tool SK7450 × 100 CNC thread grinder, Anyang Xin Sheng production SK7450 × 90 CNC thread grinder, as well as the Han River Machine, Shanghai Machine Tool production SK7450 × 50 CNC thread grinder; the other is using hard-spin CNC milling technology, a cutting forming milling, production of large heavy ball screw, The main equipments are imported PW160-type, PW300HP CNC milling machine cyclone, the domestic production of 6 meters Hanjiang Machine Tool CNC milling machine cyclone. The cost of production in foreign countries due to other reasons, multi-use hard rotary milling technology and cold forming technology to process large heavy-load ball screw has been rarely used precision grinding techniques to produce a large ball screw. The cold forming process is difficult due to the product precision is low, cycle, big error, at present at home or blank.

Testing equipment is currently almost all domestic enterprises, Chinese-made equipment, mainly dynamic precision measuring instrument. Instrument accuracy, reliability, and other indicators have reached international advanced level, to meet the needs of production, and completely replace the imports, but the lack of nuts, rail slider measuring instrument, as well as an integrated performance measurement instrument, the lack of reliability testing, comprehensive performance testing, life testing and other testing equipment.

Therefore, the prevalence of domestic enterprises lagged behind the accuracy of product performance indicators.

Direction for the future: National scrolling features the industry after 30 years of accumulation, the development has a certain foundation, one of key enterprises have long been engaged in development, and manufacturing engineering and technical personnel, technical team composed of skilled workers. By continuously introducing, digesting and absorbing foreign advanced technology and manufacturing equipment and testing equipment, I believe that major projects through the implementation of national science and technology, the domestic manufacturers of key enterprises will be equipped with more advanced level that has a large, specialized CNC machine tools and testing equipment, and in basic theoretical research, basic performance test, reliability, research, testing progress. Domestic key enterprises to achieve this goal, all developed their own priorities, including the level of Hanjiang Machine Tool Co., Ltd. for the domestic and foreign advanced levels, put forward five key tasks: rolling feature basic research. optimal design and advanced manufacturing technology research and application. testing technology and comprehensive performance studied. materials, heat treatment and modification of technical studies. precision and performance to maintain the reliability of technical studies. Hope that, through the implementation of major projects in these breakthrough features that make the domestic rolling from the price advantage into brand advantage.
