On December 11, Gelonghui reported that Wuhan Huazhong Numerical Control (300161.SZ) stated on the investor interaction platform that foreign restrictions on China's numerical control system technology mainly focus on high-end markets and key fields. However, with the continuous improvement of domestic technology and policy support, the opportunities for domestic replacement are gradually increasing, especially in the application of high-end key areas. As a leading enterprise in domestic mid-to-high-end numerical control systems, after years of research and development accumulation, the company currently has completely independent intellectual property rights for high-end numerical control system products with multi-axis linkage, achieving the domestic manufacturing of corresponding core components (such as control devices, Servo Motors, etc.), breaking the foreign technological blockade and achieving import substitution.
