A review of tube inner surface polishing technologies and development

Tube is a common structure in daily life and industrial production, and its quality directly affects the performance and life of the piping system. Polishing of inner surfaces to obtain high-precision surfaces plays a crucial role in aerospace, petrochemical and medical fields. In order to improve the adaptability of tubes and polishing methods, this paper takes a unique approach and classifies existing polishing methods from five aspects: mechanical field, magnetic field, electric field, chemical field, and ultrasonic field, so as to help optimize and upgrade the polishing technology of tube inner surface. On the basis of domestic and foreign literature, the paper summarizes the processing principles of different methods in single-field polishing and multi-field coupling polishing, as well as the factors affecting the processing efficiency, and analyzes the surface quality of workpieces with different materials and sizes after polishing. Finally, the development status of inner surface processing technology is summarized, and the future inner surface polishing will develop towards non-damage, environmental protection, high efficiency, and automation.
