According to a research report by CITIC Securities, as a transmission component with superior performance, lead screws, on the one hand, benefit from the background of autonomous and controllable industrial machine tools, and the domestic substitution of ball screws is accelerating; on the other hand, they benefit more from the rapid iteration of AI, and the humanoid robot market has exploded. Its trunk linear actuators and dexterous hand actuators have high requirements for lead screws. Taking T as an example, lead screws account for about 19% of the value of humanoid robots. In the long run, the market space brought by humanoid robots will be geometrically enlarged compared to the industrial machine tool lead screw market. In order to meet the rapidly growing demand for lead screws, high efficiency and cost reduction are inevitable trends in processing technology. It is expected that new processes such as whirlwind milling and turning instead of grinding will continue to emerge, and related equipment and consumables will benefit.
