On the application of electrochemical machining for inner surface polishing of gun barrel chamber

Inner surface polishing of complex parts with high precision can be easily done by electrochemical polishing method. In this research, cartridge house inner surface electrochemical polishing of a gun pipe, with numerous serial surface angles, is analyzed. So that, according to the various set ups, the optimized polishing parameters are obtained. The comparison between electrochemical polishing and conventional methods from this point of view, shows good advantages of this method, so that, the machining time is more than 30 times less and with very high-surface quality. Besides, the dimensional accuracy of the workpiece repeatability process in this polishing method is noticeable.
