Abstract

The invention provides a slave type array micro pit electrolytic machining method, and belongs to the technical field of electrolytic machining. The method includes the steps that a tool cathode is manufactured and composed of a metal tool and a mask plate provided with a through hole group structure, a workpiece anode and the tool cathode are connected with the positive pole and the negative pole of a power supply respectively, the workpiece anode is immersed in electrolyte, the surface of the tool cathode and the surface of the workpiece anode are tightly attached, and electrolytic machining is carried out after the power supply is turned on; after primary electrolytic machining, the power supply is cut off, the tool cathode is lifted, the electrolyte on the surface of the workpiece anode is replaced, then the surface of the tool cathode and the surface of the workpiece anode are tightly attached, and the power supply is turned on for electrolytic machining. The tool cathode is lifted and falls periodically, and electrolytic machining is carried out. Due to the fact that the tool cathode and the workpiece anode are tightly attached, generated bubbles are accumulated on the side wall of a micro pit, stray corrosion around a machining area can be effectively reduced, and locality of electrolytic machining and micro machining are remarkably improved.

Description

technical field

[0001] The invention provides a method for micro-pit arrays of follow-up electrolytic machining, which belongs to the technical field of electrolytic machining. Background technique

[0002] There are various forms of friction pairs in mechanical devices, and the contact surfaces of the friction pairs are subject to friction and wear during relative motion, resulting in reduced service life or even damage to the mechanism device, greatly reducing work efficiency and energy utilization. Friction and wear is one of the main reasons for the failure of industrial equipment. According to statistics, the annual loss of friction and wear in European and American countries accounts for about 2% to 7% of the entire gross national product, and our domestic losses in this area are also Tens of billions of RMB. Wear and tear not only consumes energy and materials, but also accelerates the scrapping of equipment, resulting in frequent replacement of parts and causing gre...
