Abstract:
As a key part in the kerosene isolation valve of LOX/Kerosene engine, the spherical valve core is featured by large diameter, thin wall and irregular shape, resulting in the difficulty of machining. Thus machining of the spherical valve core is regarded as the key technology in the development of LOX/Kerosene engine. Based on the repeated tests and thorough study on machining characteristics of wrought aluminium spherical part, a rough-semifinish-finish machining process of the spherical valve core was proposed with the optimization of machining parameters. Several cold and heat treatments and spherical finish machining with constant cutting speed make the quality and performance of the final product reliable.
