  • The development trend of high-grade CNC machine tools at home and abroad
    Time: 2017-04-25 17:19:06Copyfrom: Jiangsu Shengong Jingji machinery Co.,Ltd

          At present, rapid progress in the development of CNC machine tools and systems, as an important equipment in the field of intelligent manufacturing, in addition to implement the intelligent of the nc machine tools, network, flexibility, high speed, high precision, multiple, open, parallel drive, greening has also become a high-grade CNC machine tool such as the future focus on the development of technical direction.


          High speedSuch as automotive, defense, aviation, aerospace industry and the rapid development of the application of the new materials such as aluminum alloy, the high speed CNC machine tool processing the demand is higher and higher.


          New feature applicationsIn order to improve the performance of nc machine tools, the application of high precision and high reliability new features is inevitable.Representative new features include:In recent years, the application of linear motor is becoming more and more widely, such as: Siemens 1 fn1 series three-phase ac permanent magnet synchronous linear motor has begun to widely used in high speed milling machine, machining center, grinder, parallel machine tool, and the dynamic performance and high accuracy of machine tools, etc.;The German ex-cell-o's XHC horizontal machining center is powered by two linear motors.


          High reliabilityThe five-axis CNC machine can process complex surfaces and ensure the average trouble-free time is 20000hAbove, this is a kind of the product and the efficient use of raw materials, in its internal has many alarm measures to enable the operator handle problems in time, also has a super safe protective measures, it is the product of a kind of security, is a guarantee to the operator and society.Machine in the production of the high reliability of the machine tool more assured, more can save raw materials and artificial, it is a kind of social resource saving, however, in foreign countries, equipment the average time between failures in more than 30000 h, the existing gap to the nc machine tool enterprises in our country draw lessons from foreign technology, more and more carefully study the more perfect high-grade CNC machine tool.


          High precisionIt is precisely because of its high precision that the high grade CNC machine can reflect the standard of industrial manufacturing in a country.Along with the development of the CAM (computer-aided manufacturing) system, high-grade CNC machine tool can not only high speed, high efficiency, precision machining accuracy by yarn is the most important of evolution for micron level precision, its unique reciprocating motion unit can be extremely careful processing groove processing;The special machining precision of light, electrochemical and other energy can reach nanoscale.At the same time, after the improvement and optimization of the structure, the machining precision of the five-axis CNC machine can be entered into the submicron and even nanometer superfine age.


          multipleWith the demand of the market changing, the competition of manufacturing industry, the requirement for machine tool not only for single piece of mass production, more to be able to complete the production of small batch more varieties, the higher requirements for machine tools, mechanized production more personality.Developed composite degree higher composite machine, make its can produce a variety of large and small batch of similar production models, this is a new demand for high-end CNC machine tools, in the development of the future, will dominate, this will be a new type of numerical control machine tool to be completed by the new task.

          The process is greenWith the increasingly strict environmental and resource constraints, the green color of manufacturing processes is becoming more and more important, and China's resources and environmental problems are particularly acute.Therefore, in recent years, the machine tools that have not been used or have been used to reduce or reduce the use of cooling liquid, and have been used for cutting and drying, have been continuously developed.In the 21st century, the trend of green manufacturing will accelerate the development of various energy-saving and environment-friendly machine tools, and occupy more world markets.
