Description
Technical Field

Background
The processes currently used in machining can be divided into conventional machining and non-conventional machining.
Conventional machining is generally feasible by using mechanical energy to remove excess material from a workpiece, which is achieved by using a tool material harder than the workpiece material. However, when the workpiece material is harder and the machining surface is more complicated, the conventional machining process may limit productivity and affect machining quality, and sometimes even may fail to machine the workpiece; if the wall thickness of the workpiece is smaller and smaller (the wall thickness is less than 0.5 mm), the workpiece to be machined is easy to damage due to the action of mechanical force in the traditional machining, and the machining task is difficult to complete.
The non-traditional machining, namely special machining, realizes the machining of hard workpieces by soft tools, mainly adopts energy such as electricity, chemistry, light, sound, heat and the like to carry out machining, and no obvious mechanical cutting force exists between the tools and the workpieces in the machining process. In the special machining method, the electric spark machining precision is high, but the machining efficiency is low; the electrolytic machining is efficient, but the machining accuracy is poor. In order to improve the precision of electrolytic processing, the electrolyte must be filtered clear.
The electrolytic machining is non-contact machining, a certain gap must be kept between a cathode and an anode in the machining, and the small-gap machining is an effective measure for improving the electrolytic machining precision. The gap is filled with electrolyte in the machining process, and products dissolved by the anode in the electrolytic machining are completely dissolved in the electrolyte, so that the electrolytic machining cannot be normally carried out if the electrolyte in the machining gap cannot be updated in time, and even a short circuit phenomenon is generated in the small-gap machining. Therefore, in order to improve the precision of electrolytic processing, it is necessary to filter the electrolytic solution to be clear.
