A milestone achievement has been made in China’s high-end equipment manufacturing industry as a leading domestic CNC machine tool enterprise officially announced the mass supply of high-end 5-axis CNC machines to BYD. This collaboration marks the first time that domestic high-end 5-axis CNC equipment has been adopted in large-scale production of new energy vehicle (NEV) core components, realizing the critical breakthrough of self-reliance in the machining of key automotive parts such as drive motors and battery packs.
As the "brain" and "hands" of high-end manufacturing, 5-axis CNC machines are crucial for processing complex, high-precision components. Previously, the machining of BYD’s NEV core components relied heavily on imported 5-axis CNC machines from Europe and Japan, which faced challenges such as high procurement costs, long delivery cycles, and limited after-sales support. The domestic high-end 5-axis CNC machines supplied this time have undergone rigorous testing and verification, with key performance indicators such as machining accuracy, stability, and efficiency reaching international advanced levels.
According to relevant person in charge of BYD, the domestic 5-axis CNC machines have been put into use in multiple NEV production bases. They are mainly used for machining high-precision components such as motor stators, rotors, and battery pack casings. The application data shows that compared with imported equipment, the domestic machines reduce the unit machining cost by about 30% and shorten the production cycle by 20%, while ensuring the consistency and reliability of product quality. "This cooperation is a win-win for both parties. It not only enhances the cost competitiveness of our products but also promotes the upgrading of the domestic CNC machine tool industry," the person in charge added.
Industry experts pointed out that the mass supply of domestic high-end 5-axis CNC machines to BYD is a significant symbol of the maturity of China’s high-end CNC equipment industry. It breaks the long-term monopoly of foreign brands in the high-end NEV component machining field and strengthens the independent controllability of the domestic automotive industrial chain. With the accelerating development of the NEV industry, the demand for high-precision CNC machining equipment will continue to grow, providing broad space for the development of domestic CNC machine tool enterprises.
The domestic CNC machine tool enterprise stated that it will continue to deepen technological research and development, optimize product performance, and expand cooperation with more key enterprises in the automotive, aerospace, and other fields. It aims to contribute more to the localization of high-end equipment and the high-quality development of China’s manufacturing industry.
