Description

technical field [0001] The invention relates to an electrolytic machining electrode and a machining method for closed curved grooves on the inner and outer walls of a cylindrical member, and belongs to the technical field of electrolytic machining. Background technique [0002] Electrolytic machining technology is a process method that uses the principle of electrochemical anodic dissolution to process workpieces according to certain shapes and sizes with the help of formed cathodes. During the machining process, the tool electrode is the cathode, the workpiece is the anode, and a small gap is kept between the tool cathode and the workpiece anode. The electrolyte generally uses a neutral salt solution, and a DC voltage is applied between the electrodes. Under certain process parameters, the tool electrode is fed at a certain speed to maintain a small gap between the electrodes. The electrolyte circulates through the gap between the cathode and the anode, and at the same time...
