With China's rapidly advancing aerospace, shipbuilding, energy, power, defense, automotive, and construction machinery sectors, there is a growing demand for large-scale, heavy-duty, composite, and high-precision CNC machine tools. Addressing the current limitations in high-end CNC machine tools has become urgent. From transforming steel plates into intricate gears to shaping high-performance fibers into streamlined vehicle shells, no manufacturing process can function without these essential machines, often referred to as the "mother machines" of industry. Digital control has revolutionized their operation, making them the bedrock of modern industrialization and a reflection of a nation's comprehensive competitiveness.
In 2009, China initiated the "Major Science and Technology Project for High-end CNC Machine Tools and Basic Manufacturing Equipment," achieving significant progress over eight years. With an approximate output value of 70.6 billion yuan, China's high-end CNC machine tool technology has seen steady improvement, providing robust support for domestically produced equipment in critical areas. Significant strides have been made toward self-reliance in high-end CNC machine tools.
One of the major breakthroughs has been overcoming foreign monopolies in high-end CNC machine tools. Wang Decheng, Director of the Machinery Research Institute, explained that while conventional CNC machines can handle basic line and surface processing, more complex shapes require multi-axisè”动machines. These machines allow for simultaneous movement across multiple axes, enabling precise coordination between the tool and workpiece under computer numerical control (CNC) systems. However, the lack of such advanced tools has limited China's high-end manufacturing sector.
Previously, China lacked the capability to produce five-axisè”动machines, relying instead on imported CNC systems. For example, aerospace companies would scramble to use a single imported machine tool to process large ship components. Even when imported, these systems often came with backdoors that allowed foreign entities to monitor operations, posing significant risks to national defense security.
Efforts have since focused on developing large-scale CNC machining centers and lathes. Companies have introduced numerous new products meeting market demands, including advanced gantry machining centers and five-axis machining centers. Heavy-duty forging equipment now rivals international standards, and horizontal machining centers boast independent intellectual property rights. Flexible manufacturing systems have been developed, enhancing the competitiveness of China's high-end CNC machine tools on the global stage.
By the end of the Twelfth Five-Year Plan period, China's machine tool companies saw notable improvements in product design and manufacturing capabilities. Key aerospace projects, such as the Changzheng No. 5 rocket, benefited from domestically produced CNC machine tools. A production line utilizing these machines processed over 100 types of new-generation carrier rockets, docking mechanisms, and lunar exploration engineering differential mechanisms, producing more than 10,000 critical complex parts. This initiative also boosted the domestic market share of auto cover press lines to over 70%, with global shares exceeding 30%.
China’s equipment support capabilities in critical areas have grown significantly. Five-axis machining centers, for instance, are being used in aircraft structural parts, aerospace components, and missile engine parts. These tools play a crucial role in major national projects like large aircraft development and lunar exploration missions.
Significant advancements in independent innovation and reliability have been achieved. Over 30 key products, including precision horizontal machining centers, now match international standards. The 25-meter vertical column turning vertical milling lathe, for example, stands out globally for its size and capacity, representing the pinnacle of China's high-end CNC heavy machine tools.
Reliability has seen a marked improvement, with average machine tool failure times increasing from 400-500 hours to around 1,200 hours, with some products reaching over 2,000 hours. This progress has been supported by the development of numerous technical standards and specifications, some of which have been adopted internationally.
A major milestone was achieved in 2016 when China's independently proposed standard for testing the accuracy of 5-axisè”动machine tools was approved by the International Standards Committee, marking a breakthrough in high-end CNC machine tool design and testing.
Over eight years, the project resulted in 3,956 invention patent applications, 407 national and industry standards, and 2,951 new products and technologies. More than 5,500 innovative talents were trained, and 18 innovation capability platforms were established.
The CNC system, serving as the "brain" of machine tools, has been a critical area of focus. Achieving breakthroughs in CNC systems, servo motors, and servo drives has been pivotal to improving China's manufacturing equipment. Domestic CNC systems have evolved from analog and pulse systems to fully digital buses, competing with international counterparts.
By 2016, over 1,000 sets of high-end CNC systems were sold, increasing the domestic market share from less than 1% to around 5%. Mid-range CNC systems achieved mass production, with domestic market share rising from 10% to 25%.
Looking ahead, China aims to focus on key user areas such as aerospace and automotive, while advancing the development of core components and industrialization efforts. Strengthening innovation platforms, deploying demonstration projects, and cultivating talent will drive further advancements. Collaborative efforts with other national science and technology projects will ensure sustained progress toward "Made in China 2025."
China's machine tool industry has weathered its initial challenges, and in time, it will navigate the global economic tides with confidence.
