Description
Technical Field
The invention relates to the technical field of electrolytic machining, in particular to an electrolytic machining method of a laminated disc-shaped electrolytic machining tool electrode.
Background
The surface texture is a structure with patterns of pits, grooves, bulges and the like with certain sizes and distribution on the surface of the friction pair through certain processing technology. The surface texture can contain particles in friction movement, so that the abrasion of the surface of the friction pair is reduced, and the service life of the friction pair is prolonged. In the aspect of heat dissipation, the groove and the pit structure can increase the heat exchange area and improve the heat exchange efficiency. Therefore, a technique for machining the fine grooves and the pits becomes important.
The method for processing the micro-groove on the metal surface mainly comprises the technologies of micro-cutting processing, ultrasonic processing, micro-electric spark processing, LIGA technology, photoetching technology, surface shot blasting, laser surface micro-molding, electrolytic processing and the like. Due to the existence of acting force, the micro-cutting machining is easy to deform a workpiece in the machining process, and meanwhile, micro grooves and micro pits usually have the defects of burrs and the like, and need secondary machining. The surfaces of materials such as micro electric discharge machining, laser machining and the like have heat affected zones which are easy to deform. The surface shot blasting technology has a powerful effect in the processing process, and stress exists around the grooves and the pits, so that the material is deformed. The processing technologies such as the LIGA technology and the photoetching technology are complex, a special mask plate needs to be manufactured, the processing period of a workpiece is long, and the equipment investment is high. The electrolytic machining has the characteristic of removing the material in an ion form, has no force effect in the machining, has smooth surface of the machined material and no heat influence area, and can be applied to machining of micro-grooves and pits.
However, the existing electrochemical machining method for the micro-groove cannot ensure the size precision of the micro-groove and the pit while ensuring the electrochemical machining efficiency of the template, and cannot actively control the shape and size of the micro-groove and the pit.
In view of the above-mentioned drawbacks, the inventors of the present invention have finally obtained the present invention through a long period of research and practice.
