Crafted with precision machining as the core process, these components are designed to fit critical sections of drones such as power systems, transmission mechanisms, and connection points. Their shapes are customized to meet the overall design requirements of the drone, including circular and irregular structures. Core assemblies are installed at key locations like drone motor shafts, propeller connection points, and critical body joints, serving vital functions in power transmission, structural fixation, and component protection. Featuring exceptional concentricity and precision in both internal bores and external dimensions, these components precisely match drone assembly standards. They ensure dynamic balance and structural stability during flight, minimize component wear under high-speed operation, and enhance flight control accuracy and safety.
