Heavy rolling features of the market demand

China Suppliers


Along with the promotion of domestic demand, and industrial development, China's CNC machine tool show to large, high-speed, low noise, fast response to trends. CNC Gantry Milling, CNC Floor Boring, large five-sided machining center and a number of sophisticated, large-scale special equipment urgently needed a large, heavy rolling ancillary features, which indicates a large, heavy components are entering a scrolling function demand season.

        

    Given this rare opportunity for development, features a number of domestic and foreign manufacturers are rolling the corresponding new products launched in April held in Beijing CIMT2009 exhibition, more than half of the scroll feature manufacturers are focused on the introduction of the large, heavy products containing scrolling features, both of which thread grinding machine with SK7450 10 m overall precision CNC milled to 10 m precision ball screw, it also imports 8 m whirlwind milling CNC milling ball screw out of the whole 10 meters large, but also a ball nut rotating principal long ball screw-driven, and in large heavy-load linear rolling guide, the national key enterprises have launched a high-rigidity, heavy roller linear guides. glass cutting drill bits

    Features in a large heavy roll the difference at home and abroad, according to the author's personal point of view, mainly in the following areas: diamond cup grinding

    Fundamental research areas: domestic manufacturers engaged in fundamental research scrolling feature talent was virtually nonexistent. In recent years, with the increase in awareness of innovation, several major domestic manufacturers, such as: Han River Machine Co., Ltd., Nanjing process, Bot Seiko, Dalian High-gold and other enterprises to strengthen cooperation with universities, but only individual cooperation projects, the lack of systematic fundamental research, while universities may consider rolling feature is a very small industry and a lack of funds, are willing to work long been engaged in the study very few high-level personnel. And foreign, such as Germany, Japan and even Taiwan's companies in China, due to the support of the consortium, the capital adequacy, and corporate attention, attracting a number of high-level scientists engaged in basic theoretical research and new product development. cup grinding wheels

    New product development, product performance and reliability: Scrolling feature in major new plant products and compared to similar foreign products rather than just seemingly bore a striking resemblance. Are two reasons for the lack of basic theoretical research support; Second, the lack of test equipment for a variety of performance tests. I have to scroll features an advanced overseas production plant and saw the test equipment business and a considerable amount of production equipment, while the addition of several major domestic manufacturers have a limited number of test equipment, the vast majority of small businesses in this area is blank.

    Processing equipment and test equipment: internal features in a large heavy roll processing technology has made considerable progress in recent years, several major manufacturers are producing, with "columns" on behalf of the "pearl" of the high-rigidity, heavy rolling line guideways, and bulk import substitution to meet customer needs. In the ball screw manufacturing technology, the domestic production process has two mature, first used a large-scale production of precision CNC thread grinder precision ball screw, the main production equipment Hanjiang Machine Tool SK7450 × 100 CNC thread grinder, Anyang Xin Sheng production SK7450 × 90 CNC thread grinder, and the Han River Machine, Shanghai Machine Tool production SK7450 × 50 CNC thread grinder; the other is using hard spin CNC milling technology, forming a cut milling, production of large heavy ball screw, The main equipments are imported PW160-type, PW300HP NC whirlwind milling, domestic production of 6 meters Hanjiang Machine Tool CNC milling machine cyclone. As production costs in foreign countries and other reasons, to use more hard rotary milling technology and cold forming technology to process large heavy ball screw has been rarely used in precision grinding technology to process large ball screw. The cold forming process is difficult because the products of low precision, periodic error and it is now at home or blank.

    Detection devices are currently made almost exclusively of domestic enterprises and equipment, primarily the dynamic precision measuring instrument. Instrument accuracy, reliability indicators have reached international advanced level, to meet production needs, and fully replace imported, but the lack of nuts, rail slide gauge, and integrated performance measurement instrument, the lack of reliability testing, comprehensive performance testing, life testing and other testing equipment.

    Therefore, the prevalence of domestic enterprises performance indicators behind the precision of indicators.

    Direction for the future: National scrolling feature industry after 30 years of accumulation, the development already had a foundation, key backbone enterprise has a long been engaged in research and manufacture of engineering technicians, technical ?? Zucheng technical team. 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 focus of key manufacturing enterprises will be equipped with more advanced level with a large professional CNC machine tools and testing equipment, and fundamental research, basic performance test, reliability studies, testing progress.

    Domestic key enterprises to achieve this goal, both developed their own work, which highlight the level of Hanjiang Machine Tool Co., Ltd. for the domestic and foreign advanced level, raised five key tasks: ? scrolling feature basic research. ? Optimal design and advanced manufacturing technology research and application. ? Testing and Comprehensive Performance. ? materials, heat treatment and modified technique. ? accuracy to maintain the reliability and performance technology. Hope that, through the implementation of major projects, in the breakthrough, rolling features that make the domestic cost advantage into the brand.
