Background

Electrochemical machining is a special machining method for machining and forming a workpiece by utilizing the principle that metal is subjected to electrochemical anodic dissolution in electrolyte. During machining, the workpiece is connected with the positive pole of a direct current power supply, the tool is connected with the negative pole, and a small gap is kept between the two poles. The electrolyte flows through the interelectrode gap to form a conductive path between the two electrodes, and generates a current under a power supply voltage, thereby forming electrochemical anodic dissolution. With the continuous feeding of the tool relative to the workpiece, the metal of the workpiece is continuously electrolyzed, the electrolysis product is continuously washed away by the electrolyte, finally, the gaps at all positions between the two electrodes tend to be consistent, and the surface of the workpiece is formed into a shape basically similar to the working surface of the tool. Because the products dissolved by the anode in the electrolytic machining are completely dissolved in the electrolyte, if the electrolyte in the machining gap cannot be updated in time, the electrolytic machining cannot be normally carried out, even a short circuit phenomenon is generated in the machining of the small gap, and in order to improve the precision of the electrolytic machining, the electrolyte must be filtered to be clear.
