Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrolytic processing equipment, in particular to a monitorable electrolytic polishing equipment. BACKGROUND

[0002] Electrolytic polishing is a kind of polishing method which makes the protruding part of the anode selectively dissolve to form a smooth surface by using the principle of anode dissolution in electrochemical reaction, and belongs to the category of special processing. The workpiece to be polished and the tool electrode are put into the electrolyte, the workpiece is connected to the positive pole of the electrolysis power supply, the tool electrode is connected to the negative pole of the electrolysis power supply, and a certain gap is left between the workpiece and the tool. After starting the power supply, the workpiece, tool cathode, wire and electrolyte form a loop. Under the action of the applied potential, the workpiece anode loses electrons and dissolves, forming a salt film on the surface of the workpiece. The thickness of the film is small at the protruding part of the workpiece surface, the current density is large, and the dissolution rate is large; while the film thickness is large at the recessed part, the current density is small, and the dissolution rate is small. Based on the above principle, the surface roughness of the workpiece is gradually reduced, and the surface quality and gloss are further improved to meet the specific use requirements.

[0003] However, the existing electrolytic polishing technology has a common problem that the electrolyte in the electrolytic tank used in industrial applications is turbid and mixed with a large number of bubbles, and the operator cannot see the working condition under the liquid surface, nor can the operator realize real-time monitoring of the polished surface of the workpiece during the processing, and it is difficult to observe and record the processing process; and when the workpiece profile is complex, under the action of large current, the current density at different positions differs greatly, which easily causes size distortion, especially for workpieces with high size precision, which will be directly scrapped due to over-difference.
