Analysis of the Four Trends of Future Machine Tool Technology Development

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

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

Using techniques such as temperature and vibration error compensation, the geometric accuracy and motion accuracy of CNC machine tools are improved. At present, the precision of ordinary CNC machine tools can reach 5 to 10 microns, the precision machining center can reach 1 to 1.5 microns; the precision of ultra-precision machining centers can reach nanometer.

Integration is also one of the most important development trends of CNC machine tools. After 2010, CNC machine tools are closely integrated with intelligent technology and network technology, and can be remotely controlled and diagnosed through the Internet, laying a foundation for the integration of CNC machine tools into the Internet of Things era. Greening has become a new direction in the design, manufacture and use of CNC machine tools. Countries have gradually incorporated greening into research and development, such as the use of renewable materials in the design process; in the process of working, the use of frequency conversion technology to reduce idle speed and energy consumption; to reduce the waste discharge of more than 50% in 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 range, processing quality and production efficiency, the global CNC machine tool industry has made revolutionary progress and played a key role in improving the level of high-end manufacturing.

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