Description

[0001] technical field [0002] The invention belongs to the field of precision electrolytic processing devices, in particular to a device for realizing the combination of cathode feeding motion and vibration motion in the electrolytic processing process. Background technique [0003] Electrolytic machining is a special processing technology, which is a processing method that uses the principle of electrochemical anodic dissolution to remove materials. Compared with traditional mechanical processing methods, it has the advantages of fast processing speed, good surface quality, no loss of tool cathode, wide processing range and no macro cutting force, etc. It has been widely used in aerospace, instrumentation, mold manufacturing and other fields. However, the anodic dissolution process of electrolytic machining is in a very complex environment, affected by electric field, flow field, temperature, electrochemical parameters, etc., and the parameters are coupled with each other...
