　　As machines used in manufacturing, machine tools play an important role in the manufacturing industry. Machine tools are capable of processing metal or other material blanks or workpieces to achieve the required geometric shape, dimensional accuracy, and surface quality, and are also known as "industrial mother machines".

　　Numerical control machine tools are machines that use digital information to control the motion and processing of machine tools. They are modern electromechanical integrated equipment with high efficiency, precision, flexibility, and automation.used excavator used excavator used excavator used excavator

　　Overall, on the one hand, there is still significant room for improvement in the CNC rate of machine tools in China; On the other hand, currently, China's low-end CNC machine tools have basically achieved self-sufficiency, and mid-range CNC machine tools have basically been replaced by domestic production. However, the localization rate of high-end CNC machine tools is still at a relatively low level. Enterprises led by Kede CNC (688305. SH), Huazhong CNC (300161. SZ), Zhongke Weijing, Haitian Precision (688182. SH), Neway CNC (688697. SH), Yuhuan CNC (002903. SZ), etc. are constantly exploring the high-end machine tool market.

　　China is the largest manufacturer and consumer of machine tools, and the CNC rate needs to be improvedused excavator used excavator used excavator used

　　China is the world's largest manufacturer and consumer of machine tools. According to data from the German Machine Tool Manufacturers Association, China's machine tool output value will be approximately 181.8 billion yuan in 2022, accounting for 32.0% of the world's total; The consumption of machine tools is about 183.92 billion yuan, accounting for 32.2% of the world's total; The output value and sales revenue of machine tools are both ranked first in the world.

　　Machine tools mainly include metal cutting machines, metal forming machines, and special processing machines.

　　Taking metal cutting machine tools as an example (the National Bureau of Statistics only counted metal cutting machine tools), according to MIR Industry data, in recent years, China's metal cutting machine tools have reached 80 billion to 110 billion yuan, and in 2023, it will be about 80.8 billion yuan. In 2023, the export value of China's metal cutting machine tools will reach 11.95 billion yuan, and the compound annual growth rate from 2019 to 2023 will reach 30%. It is expected that the export value will reach 15 billion yuan in 2024, and the number will continue to increase in 2025.used excavator used excavator used excavator used excavator

　　The periodic variation characteristics of metal cutting machine tools are extremely significant, usually manifested as a large cycle every 10 years and a small cycle every 3-4 years. 2023 and 2024 are at the end of the large cycle replacement wave and the starting point of the fluctuation cycle. From the perspective of the service life of machine tools, MIR predicts that the domestic market will enter a new upward cycle in the next decade. The compound annual growth rate is expected to reach around 2% from 2024 to 2028.used excavator used excavator used excavator used excavator used excavator used excavator used excavator used excavator used excavator used

　　Since 2020, the localization rate of machine tools in China has also significantly improved, with the fastest growth rate in 2020, an increase of 4 percentage points compared to 2019. According to MIR Industry data, as of 2023, the localization rate of Chinese machine tools has increased to 55%.

　　However, there is still significant room for improvement in the CNC rate of machine tools in our country. According to data from the China Machine Tool Industry Association, the CNC rate of metal cutting machine tools will be 45.5% in 2023. The CNC rate of Japanese machine tools remains above 80%, while the CNC rates of machine tools in the United States and Germany both exceed 70%.used excavator used excavator used excavator used excavator

　　The Action Plan for Promoting Large scale Equipment Renewal and Consumer Goods Trade in issued by the State Council in early 2024 proposes to deepen the remanufacturing of traditional equipment such as machine tools. By 2027, the penetration rate of digital research and development design tools and the CNC rate of key processes in industrial enterprises above designated size will exceed 90% and 75%, respectively.

　　CNC machine tools can be divided into low-end, mid-range, and high-end CNC machine tools. "The production capacity of low-end CNC machine tools in China is relatively surplus, and the industry competition pressure is high. Everyone is competing for cost and efficiency; but for high-end CNC machine tools with high processing quality and accuracy, the overall gap in China is constantly narrowing. For example, some sub fields such as ultra fast laser microfabrication have achieved catch-up." Wang Zi, the director of Zhongke Micro Precision Innovation Research Institute, which focuses on ultra fast laser processing CNC machine tools, told First Financial, "Especially for CNC machine tool products that process complex surfacesused excavator used excavator used excavator used excavator

　　According to data from the China Business Industry Research Institute, the localization rate of high-end CNC machine tools in China is expected to be around 6% in 2023.used excavator used excavator used excavator used excavator

　　The CNC machine tool market in China can be roughly divided into three tiers: firstly, international machine tool companies represented by DMG, Yamazaki Mazak, Makino, etc. occupy the majority of the high-end market share; Secondly, large state-owned enterprises represented by Jinan Second Machine Tool, Shanghai Machine Tool, Qinchuan Machine Tool, Haitian Precision, Neway CNC, Kede CNC, Yuhuan CNC, and some private enterprises with core competitiveness mainly occupy the mid-range market; The third is the low-end market composed of numerous small and medium-sized enterprises.used excavator used excavator used excavator used excavator

　　It is reported that the current five axis linkage technology represents the highest level of technology in the field of machine tools and is an ideal machine for complex surface machining.used excavator used excavator used excavator used excavator used excavator used excavator used excavator used excavator

　　Compared with traditional three-axis and four axis CNC machine tools, the most significant feature of five axis linkage CNC machine tools is multi axis linkage, which can achieve simultaneous linkage of five axes, including X, Y, Z axes and two rotation axes. This multi axis linkage structure enables five axis CNC machine tools to perform machining in more directions and achieve more complex machining tasks. It is the only means to solve the cutting and machining of key industrial products such as aerospace and aviation engine impellers, blades, blades, and marine propellers.

　　China's five axis machine tools are mainly concentrated in industries such as aerospace, military, molds, automobiles, and ships. Currently, domestic demand continues to grow. MIR predicts that the market size of China's five axis machining centers will exceed 10 billion yuan by 2024, and may reach 20 billion yuan after 2028, entering a new round of growth stage. The market size will continue to grow in the next five years.used excavator used excavator used excavator used excavator

　　With the continuous improvement of technical capabilities of enterprises such as Beijing Jingdiao, Kede CNC, Shanghai Tuopu, and Evermi, domestic manufacturers are gradually opening up the five axis market. Among them, Kede CNC five axis linkage CNC machine tools entered the aerospace field in the early days and expanded into the civilian field in recent years. According to its investor exchange minutes, the revenue from the civilian field accounts for about 30% -40% of the newly added orders in China, and the quantity accounts for more than 70%.used excavator used excavator used excavator used excavator

　　To achieve more breakthroughs in high-end CNC machine tools, improving accuracy is the key, and the accuracy and reliability of upstream core components have a significant impact on machine tool performance. The core components of CNC machine tools mainly include CNC systems, encoders, grating rulers, ball screws, spindles, guide rails, turntables, etc.used excavator used excavator used excavator used excavator

　　In terms of software, Open Source Securities believes that the main bottleneck for domestic production lies in the error compensation capability of CNC systems, as well as the inability of servo system acceleration and deceleration control accuracy to meet the requirements of high-end CNC machine tools.

　　According to insiders from Huazhong CNC who specialize in CNC systems, as the "brain" of CNC machine tools, CNC systems account for about 20% of the total cost of CNC machine tools. The Huazhong 8-type CNC system is a domestically produced high-end CNC system with five axis linkage technology, which can compete with foreign high-end CNC systems in key technical indicators such as multi-channel and multiple linkage.used excavator used excavator used excavator used excavator

　　It is reported that around 2017, third-party organizations conducted tests on the high-performance CNC system of Huazhong CNC Huazhong 8, comprehensively benchmarking the functions of high-performance CNC system products from countries such as Germany and Japan. More than 600 functions of standard CNC system products have a matching degree of 100%, and more than 1900 functions of high-end CNC system products have a matching degree of over 98%.

　　In terms of hardware, Open Source Securities stated that the main bottleneck for domestic production is the thermal deformation, rigidity, stress, accuracy, and other issues of components such as screws/guides, bearings, cutting tools, and body materials. Domestic manufacturers such as Aopu Optoelectronics (002338. SZ) and Haozhi Electromechanical (300503. SZ) are making efforts to catch up. The "Key Field Technology Roadmap" released by the Ministry of Industry and Information Technology has clearly defined the development goals of high-end CNC machine tools. By 2025, the domestic market share of high-end CNC machine tools and basic manufacturing equipment, as well as mid to high end functional components such as spindles, screw rods, and wire tracks, will reach 80% in China.

　　In fact, the more we move towards the high-end, the lower the degree of generalization of CNC machine tools. High end CNC machine tools are often customized products developed for a specific niche field, requiring not only the CNC machine tool itself, but also processing solutions for some industries. From this perspective, components such as CNC systems, as well as light sources and lasers involved in our laser processing field, and even upstream CAD software, are the key technological focus and continuous research and development objects for future high-end CNC machine tools, "said Wang Zi.used excavator used excavator used excavator used

　　On the other hand, the development of high-end CNC machine tools in China also needs to improve stability.

　　I think there is not much difference in the accuracy of machine tools between China and foreign countries. What is more important is the maintenance of our accuracy and the stability of the machine tools. In terms of stability, there is actually a big gap between us and foreign countries, "Wang Zi told First Financial." Machine tool stability is a complex engineering problem that involves the engineering technology of the entire chain, including raw materials, design, assembly, maintenance, and upkeep

　　To enhance stability, Wang Zi introduced that at the technical level, Zhongke Weijing has laid out adaptive technologies such as machine tool compensation technology and environmental stability control technology; At the management level, we have established standardized standards for the maintenance and upkeep of machine tools to ensure their long-term stability during use.used excavator used excavator used excavator used excavator

　　Huazhong CNC related personnel stated that the maturity and stability of the product are closely related to the testing and verification of the application end. The testing and verification of domestic CNC systems in various application scenarios are not sufficient. Software products themselves need to constantly receive user feedback and iterate updates to achieve a spiral increase in product maturity and stability. We are also constantly optimizing this aspect. In the future, CNC machine tools will gradually transform into intelligent machine tools, and the level of intelligence of CNC machine tools will continue to improve to lower the threshold for their use

　　Wang Zi also has a similar viewpoint. At present, many CNC machine tools and CNC systems require experienced craftsmen from major countries to operate well and produce higher precision products, which places high demands on the abilities of craftsmen. In the future, by introducing AI, engineers' experience will become the ability of the equipment itself, and it will have self-learning ability like humans. The production results of the machine tools will be fed back to the control system and decision-making layer, and the brain of the equipment will continuously learn and iterate to continuously improve its production capacityused excavator used excavator used excavator used

　　According to relevant personnel from Huazhong CNC, the 9-type CNC system of Huazhong CNC is the world's first intelligent CNC system embedded with AI chips. It integrates AI chips, AI algorithms, big data, big models, and strong computing power, forming a truly intelligent CNC system platform. It has AI consultation and processing code generation functions based on big models, achieving a major breakthrough in the global CNC system market.used excavator used excavator used excavator used

　　AI fault diagnosis is the process of learning accumulated knowledge from the past to determine the possible causes of machine tool failures, identify problem points, and provide solutions. Currently, the system is equivalent to the level of an engineer with two years of experience; generating machining codes can make programming more convenient, that is, informing the CNC system of what kind of component needs to be machined, proposing machining requirements, and the system will automatically generate reference codes and issue them to the machine tool. As knowledge continues to accumulate and learn, the experience of the CNC system will become richer, and the threshold for efficient use of CNC machine tools will become lower and lower, "said a person related to Huazhong CNC.

　　However, as mentioned earlier, the improvement of product accuracy, maturity, and stability cannot be achieved without the continuous verification process on the application side. Currently, there is still significant room for improvement in the CNC rate of machine tools in China. Therefore, intelligent machine tool products are still far from maturity and need to undergo continuous optimization, upgrading, and iterative innovation.
