Abstract: Aiming at solving the problem of how to reduce the cost of the production and steadily obtain the perfect workpiece with less subsurface damage, the machining mechanism of atomic ultrasmooth surface technology was analyzed, the machining mechanism and the latest research of the existing noncontact polishing methods were summarized, especially about the research of acoustic suspension polishing and abrasive jet polishing. Furthermore, their advantages and disadvantages were also compared in all aspects. Finally, according to the existing problems of ultrasmooth surface polishing technology, the probable further study of the technology was proposed. The result indicates that adopting the noncontact polishing method and controlling the machining process reasonably can greatly reduce the roughness of workpiece and improve the subsurface damage. The requirements of polishing equipment precision are higher for the noncontact polishing at present, which requires reducing the manufacturing cost to largely promote the ultrasmooth surface processing technology.
