Editor's note: Luo Baihui, a researcher at the China International Economic Development Research Center, pointed out that China's CNC machine tool industry has experienced a period of passion and will usher in an era of rational development. The eleventh five-year plan is a period of rapid development of CNC machine tools in China, and the twelfth five-year plan will be a strategic opportunity for the development of CNC machine tools.
The strategic opportunity for the development of CNC machine tools The so-called strategic opportunities refer to a special period that has a significant impact on the development of the entire industry in a relatively long period of time and in a relatively broad space. The strategic opportunities are rare. Grasping strategic opportunities and accelerating development is the strategy for China's CNC machine tool industry to win.
"Eleventh Five-Year" China's national economy under the guidance of the scientific concept of development will be more stable and orderly development; the State Council's decision to revitalize the equipment manufacturing industry will greatly accelerate the development process of China's equipment manufacturing industry, especially the country's key support Development of major equipment, such as large-scale power generation, power transmission and transformation equipment, large-scale petrochemical and coal chemical installations, mining equipment, complete sets of rolling equipment, large-scale marine vessels, high-speed trains, and large-scale surface rock tunnelling machines represented by construction machinery and civil aviation Aircraft and engines, etc., need to provide a large number of heavy, precision, multi-coordinate, high-efficiency, special-purpose CNC machine tools for processing and manufacturing. The development needs of the country's major equipment indicate the direction for the development of the CNC machine tool industry.
The key to the economic development of the “Eleventh Five-Year Plan†is to realize the transformation of the economic growth mode. The advanced manufacturing industry is the direction of transformation of traditional manufacturing industries. The traditional industries such as automobiles, machinery, household appliances, textiles, agricultural machinery, and environmental protection industries are undergoing technological transformation. The demand for CNC machine tools continues to climb; the development of high-tech industries such as electronic information, bio-engineering, and new energy and new materials has opened up new demands for precision, high-efficiency, and dedicated CNC machine tools; from the perspective of regional development, the upgrading of China's eastern industries has become a reality. The rejuvenation of old industrial bases and the development of the Midwest accelerate the pace, providing domestic markets for the development of CNC machine tools; economic globalization, the transfer of international capital and industries to China, the exchange of international technology and talents, and the strong development of China's international trade, etc. , Providing an external environment for the development of China's CNC machine tool industry, so that we are in a rare strategic development period.
The development focus of CNC machine tools industry is based on the development trend of international CNC machine tools industry and the national economic development requirements of China's "Eleventh Five-Year Plan". The key points of the "Eleventh Five-Year" CNC machine tool industry are: development of large-scale, precision, high-speed CNC equipment and numerical control systems and The functional components change the status quo that most large-scale, high-precision CNC machine tools rely on imports to meet the industrial development of machinery, aerospace and other industries.

A solder ring fitting, also known by the trademarked name Yorkshire fitting,is a pre-soldered capillary connector for joining copper pipes used in plumbing.While less convenient than compression joints and less reliable than flux solder joints, they are useful when fitting in confined spaces and where single handed fitting is required.
To obtain perfect joins, the inside of the fitting and the outside of the copper pipe are cleaned using coarse steel wool, flux paste is applied, the pipe is inserted into the fitting and heat applied from a portable propane torch until a ring of solder shows at the edges of the fitting. To obtain a durable joint, water must not be poured on the solder joint to cool it. Yorkshire fittings are now made with lead-free solder.The fittings come in a great variety of configurations, such as Tee-pieces, straight couplers, elbows or bends, reducers (to join pipes of different diameters), stop-ends, and there are versions with screw threads (male or female) at one end to fit taps and galvanized iron pipes.Valves such as stoptaps & gate valves are also available in solder ring configuration.
