It makes full use of their advantages in electrochemical finishing and mechanical finishing, and is a finishing method under the conditions of the matching between the electrochemical anodic dissolution and abrasive mechanical scraping action. Based on the cylinderical bearing roller electrochemical mechanical finishing device, we conducted in-depth research, introduced the finishing machining?principle and technical characteristics in the paper. And their each processed surface geometrical topography were compared. The result indicated that the composite processing have a better advantage. And in the part of the device design, I designed the cathode head and each movement mechanism, as well as the electrolyte system, and making the sandwich type cathode head, which adjust conveniently, in order to achieve the matching of the combined effects and ensure the finishing effect, effectively reduce the bearing roller surface roughness. In addition, checking the processing equipment parts is used to ensure the operation safe and stable, and have sufficient strength. In this paper the design of cylindrical bearing roller electrochemical mechanical finishing device has the advantages of simple structure，easy to operating， and is convenient for wide application.
