Case Study | Application of Head Spin-Forming Equipment at Capital Aerospace Machinery Co., Ltd. (China Aerospace Long March Rocket)

The head spinning machine supplied by Wuxi Dongyang Spinning Equipment Co., Ltd. is used in the forming and manufacturing of critical components for aerospace rockets:

1. It enables the seamless integral spinning and forming of rocket fuel tanks and pressure vessel end caps, eliminating welded joints and thereby removing weld-related weak points, effectively enhancing the structural strength and fatigue resistance of the components, thus meeting the stringent technical requirements of aerospace equipment for high-pressure load-bearing and lightweight manufacturing;

2. The wall-thickness reduction during spinning is precisely controllable, resulting in excellent roundness and high consistency in the external profile of the finished product, ensuring uniform and stable stress distribution on the shell during high-speed flight;

3. The workpiece surface exhibits shallow roller marks and excellent surface finish, significantly reducing subsequent grinding and finishing processes, making it well-suited to the precision forming needs of aerospace special components made from aluminum alloys, high-strength special alloys, and other materials.
