Description
Technical Field

When the micro-structure is processed by electrolysis, how to realize high-quality and high-efficiency processing and exerting the advantages of the electrolysis processing are the research contents which must be developed in the application of the electrolysis processing technology engineering. The electrolytic machining precision is improved to a certain extent through the modes of side wall insulation, masking and the like, but the cathode needs to be machined, and the traditional mask electrolytic machining needs to cover a layer of photoresist or a masking layer (electrical insulation) on the surface of a workpiece. In addition, in most cases, when the mask layer is processed, the electrolyte is static, and the products in the processing area can only be transferred by diffusion, natural convection and the like, so that the processing efficiency is low and the mask layer is easy to peel off.
In order to solve the problems that the mask cannot be reused, the processing efficiency is low and the like, a laser surface modification technology is introduced into the manufacturing of the mask, and then the surface structure is processed through electrolytic processing, namely an electrolytic laser composite processing technology.

However, most of the existing laser composite electrolytic machining equipment is special machine, is only suitable for machining one or more parts, and has poor universality. The laser composite electrolytic machining equipment comprises a laser promoting machining area and a laser mask restraining non-machining area, wherein the laser promoting electrolytic machining equipment is divided into a laser promoting machining area and a laser mask restraining non-machining area, and the laser and electrolyte share a common path, so that the problem of laser power attenuation is unavoidable; the existing laser mask equipment is heavy, and once the laser mask equipment is installed, the later-stage moving and leveling steps are complicated.
