In recent years, the development of CNC machine tools in China has been very rapid, and various types of CNC machining machines have been continuously researched and developed like mushrooms after rain. The development of low-end machine tools is significant, but the research and development of high-end machine tool equipment always relies on the introduction and replication model. Overall, there is a strong dependence on foreign technology and a lack of independent high-end machine tool intellectual property rights.
The domestic machine tool industry has always been responsible for developing high-end CNC machine tools, supporting the construction of key domestic projects and military projects. The domestically produced XNZD2415 five axis machine tool combines the characteristics of traditional machine tools and parallel machine tools, and also sets a precedent in technological innovation.
Having its own safe and reliable control system, it can achieve good human-machine interaction and high-precision five axis linkage. And the machine tool has a wide range of operations and strong practicality. Domestic milling machines have also achieved five axis linkage technology, using high-tech such as tool internal cooling and stress control. It can be used for processing submarine turbines, complex cavity molds, aerospace, military and other high difficulty and high-quality requirements. The domestic flexible manufacturing system has also made significant progress, adopting a combination of simulated processing and actual processing, which not only improves processing quality and efficiency but also greatly reduces processing costs and cycles.
However, the development of the machine tool industry in various countries around the world, especially developed countries, has already left the primary stage and entered the higher level of ultra-high precision, ultra-high efficiency, and ultra-high quality fields. The technological level of various high-tech CNC machining machine tools exceeds the current development of the domestic machine tool industry. Although the domestic machine tool industry is developing rapidly, it is still in the primary stage where developed countries have already completed the transition.
In the past decade, China's machine tool industry has developed rapidly, attributed to the urgent needs of the rapidly developing manufacturing industry in China. Although the development of machine tools has been rapid in recent years and sales have been huge, a large part of them are low-end CNC machine tools, which has also contributed to the low level of China's basic manufacturing industry. For most high-end CNC machine tools and special machining machine tools, a large amount of imports are still needed, and China lacks its own intellectual property rights in this regard, which has always been in a passive position. The demand for machine tools in China is expected to remain high in the coming years, accounting for a significant proportion of the world's total demand for machine tools. If the technology of China's machine tool industry, especially the high-end technology of CNC machining machines, continues to be lacking, China's machine tool industry and manufacturing industry will be in a passive development mode.
The current problems in the domestic CNC machine tool industry
There are many problems in China's CNC machining industry, mainly including the lack of guidance from developed countries to improve policies in the following areas; The extreme shortage of high-end technical talents in scientific research work is superficial and not in-depth in technology, relying solely on the lack of close cooperation and disconnection among various sub departments in the assembly type aerospace machine tool industry. Although there are many researchers, they are only considering the urgent need to improve their overall quality and competence.
