Introduction: At the 18th CIMT 2023 China International Machine Tool Exhibition held in April this year, the trend of high-end, intelligent, and green development was comprehensively presented, as well as the integration and development of innovative technology, integrated composite technology, digital interconnection, green technology, and machine tool equipment. The rapidly changing industrial automation components and CNC technology provide strong technical support for the popularization and application of high-end CNC machine tools, including five axis linkage.
The most impressive aspect of this year's CIMT exhibition is the rapid development of high-end CNC machine tools, which is truly breathtaking. One of the more obvious phenomena is that five axis linkage CNC machine tools have become a must-have exhibit for every exhibitor, to the point where one exhibitor exclaimed, "If there weren't a five axis machine tool, I wouldn't be able to come to the exhibition; In addition, many companies have showcased machine tools with a precision of micrometers (1 μ), and even proposed sub micrometer machining. It can be said that the current trend of China's manufacturing industry rising towards high-value industrial chains has provided a good soil for the development of the CNC machine tool industry.
According to data, the CNC rate of domestic machine tools was 44.9% in 2021, and according to the "Made in China 2025" plan, the CNC rate of key processes will be increased to 64% by 2025. This shows that there is still significant room for improvement in the CNC rate of domestic machine tools. Industry insiders have pointed out that after years of development, the domestic market has
Machine tool companies have already mastered the basic mechanical structure of CNC machine tools, and it can be preliminarily predicted that the main mechanical structure of CNC machine tools will not undergo significant changes in the next 10-20 years. In the next stage, CNC machine tools will develop towards high precision, efficiency, and intelligence. Therefore, high-efficiency functional components such as electric spindles and linear motors will be increasingly applied to transmission systems. Control technology, especially remote maintenance and management based on the Internet, five axis linkage control technology, human-machine engineering operation technology, thermal deformation and compensation technology, are the key development areas of the machine tool industry.
Popularization of application of five axis linkage CNC machine tools
According to data released by QYResearch, the global market sales of five axis linkage CNC machine tools reached 6.755 billion US dollars in 2020, 7.48 billion US dollars in 2021, and are expected to reach 13.835 billion US dollars by 2027, with a compound annual growth rate of about 10.79% from 2020 to 2027 (see Figure 1); In 2020, the domestic market size of five axis linkage CNC machine tools was about 665 million US dollars, accounting for about 9.85% of the global market. It is expected to reach 1.589 billion US dollars by 2027, and its market share in the global market will reach 11.49%. The compound annual growth rate from 2020 to 2027 is about 13.25%, which is higher than the global market.
