High speed has always been the goal of NC machine tools. Since 1990, European and American countries have applied new machine tool kinematics theory and advanced driving technology to optimize the structure of machine tools, improve the performance of functional parts, lightweight mobile parts and reduce motion friction. The application of high-speed machining technology shortens the cutting time and auxiliary time, and realizes the high quality and high efficiency of machining and manufacturing.

Precision has become an important performance parameter of CNC machine tools. By optimizing the structure of the machine tool, the accuracy of manufacturing and assembly is improved, and the reaction time of NC and servo system is reduced.

The geometric accuracy and motion accuracy of NC machine tool are improved by using temperature and vibration error compensation technology. At present, the machining accuracy of ordinary CNC machine tools can reach 5 to 10 microns, and the precision level can reach 1 to 1.5 microns; The precision of ultra precision machining center can reach nanometer level.

Integration is also one of the most important development trends of NC machine tool technology. After 2010, CNC machine tools are closely combined with intelligent technology and network technology, and can be remotely controlled and diagnosed through the Internet, which has laid a foundation for the integration of CNC machine tools into the times. Green has become a new direction in the design, manufacture and use of CNC machine tools. Countries gradually bring greening into the scope of R & D, such as the extensive use of renewable materials in the design process; In the working process, frequency conversion technology is adopted to reduce idle speed and energy consumption; Reduce the waste emission by more than 50% during the use of CNC machine tools.

High speed, precision, integration and greening have become the development direction of CNC machine tool industry technology. In terms of equipment level, processing scope, processing quality and production efficiency, the global CNC machine tool industry has made revolutionary progress, which has played a key role in improving the level of high-end manufacturing industry.

During the 12th Five Year Plan period, China will continue to invest and intensify its efforts. Major special projects will drive the investment of more than 10 billion yuan every year. It not only drives the market development of China's domestic CNC machine tools, CNC systems and related functional components, but also provides an excellent opportunity for domestic CNC system manufacturers to continuously develop their own technology and expand the market.
