The impact of five-axis machine tools on industry and their strategic value

In traditional mold machining, vertical machining centers are generally used to complete the milling of workpieces. As mold manufacturing technology continues to develop

The first development trend is the adoption of linear motor drive technology. After more than a decade of development, linear motor technology has become very mature. The problems of linear motors being prone to interference and generating a lot of heat when they were first developed have been solved. Moreover, the positioning technology of linear motors, which enables them to stop quickly during high-speed movement, has also been addressed by some machine tool manufacturers through damping technology. The advantages of linear motors are linear drive, no transmission chain, no wear and no backlash, so they can achieve the best positioning accuracy. Linear motors have high dynamic performance and their acceleration can exceed 2g. The adoption of linear motor drive also features high reliability and maintenance-free operation. Secondly, it adopts dual-drive technology. For wider workbenches or gantry frame types, if intermediate drive is adopted, it is actually impossible to ensure that the driving force is at the center, which is prone to causing tilting and resulting in poor dynamic performance. With dual drives, dual grating rulers and one drive module, the dynamic performance can be made extremely perfect. With one drive command, both drives work simultaneously. The grating ruler detects whether the two points are balanced. If they are not balanced, different commands are used to make them balanced. Strategic value equipment manufacturing is the cornerstone of a country's industry. It provides important means for the development of new technologies and new products as well as modern industrial production, and is an indispensable strategic industry. Even developed industrialized countries all attach great importance to it. In recent years, with the rapid development of China's national economy and the needs of national defense construction, there has been an urgent and large-scale demand for high-end CNC machine tools. Machine tools are a symbol of a country's manufacturing level. The five-axis linkage CNC machine tool system represents the highest level of the machine tool manufacturing industry. In a sense, it reflects the industrial development level of a country. For a long time, the Western industrialized countries led by the United States have always regarded five-axis linkage CNC machine tool systems as important strategic materials and implemented an export license system. Especially during the Cold War period, it was detrimental to socialist camps such as China and the former Soviet Union
