[0015] An electrolytic polishing machine device is provided with an adjustable-speed flow pump 111. One end of the adjustable-speed flow pump 111 is connected to one end of a right-angle adapter 110, and the other end of the adjustable-speed flow pump 111 is connected to an electrolytic cell water outlet 103. The electrolytic cell water outlet 103 is arranged on the side wall of the electrolyte tank 101. The other end of the right-angle adapter 110 is connected to a flow channel 2 in the nylon grip 108. A pipeline 105 is arranged in the nylon grip 108. The space between the pipeline 105 and the inner wall of the nylon grip 108 is the flow channel 2. One end of the pipeline 105 is fixed in the nylon grip 108 through a fixing block 113, and one end of a cathode output terminal 104 is also fixed to the fixing block 113. The other end of the pipeline 105 is communicated with an opening 109b arranged on the rubber head 109. The opening of the rubber head is tightly pressed against the surface of the sample 3 to form a sealed space. The other end of the cathode output terminal 104 is connected to the negative pole of a power supply output interface 107, and the positive pole of the power supply output interface 107 is connected to an anode output terminal 106. The pipeline 105 is also communicated with an electrolyte tank water inlet 102, and the electrolyte tank water inlet 102 is arranged on the side wall of the electrolyte tank 101.
[0016] Cooling water tanks 116 are provided on both sides of the electrolyte tank 101, and a polishing probe holder 114 is also provided on the electrolyte tank 101.
[0017] The adjustable speed flow pump 111 is controlled by a control unit 112, and the control unit includes a timer and a voltage regulator.
[0018] An annular protrusion 109a is provided on the rubber head 109, and an annular groove 108a matching the shape of the annular protrusion 109a is provided at the insertion joint of the nylon grip 108 and the rubber head 109.

[0021] The working principle of the present utility model is as follows: First, fill the electrolyte tank with electrolyte, press the rubber head tightly against the surface of the sample, and connect the anode output terminal to the sample. Then start the work. The electrolyte flows out from the outlet of the electrolyte tank and starts to flow towards the adjustable speed flow pump. The adjustable speed flow pump then pushes the electrolyte to the right-angle adapter. The electrolyte flows into the interior of the flow channel from the right-angle adapter and continues to flow along the outer wall of the pipeline. When it flows to the opening of the rubber head, the electrolyte bends and flows into the inner wall of the pipeline, and an electrolytic reaction occurs between the electrolyte and the sample at the opening of the rubber head. After electrolytic polishing, the electrolyte continues to flow along the pipeline to the inlet of the electrolyte tank. After the electrolyte completes the cycle in the electrolyte tank, it continues to flow in the above steps. Ice bags can be provided in the cooling tank to cool the electrolyte in the electrolyte tank. After the set time ends, a flat corrosion surface with the same size as the opening of the rubber head will be formed on the surface of the sample. After the electrolytic polishing work is completed, the polishing head device composed of the pipeline, the right-angle adapter, the flow channel, and the nylon grip can also be placed on the polishing probe holder; the electrolyte passage formed by the closed space, the flow channel, and the pipeline disclosed in the present utility model is recycled with the electrolyte tank, and there is no liquid leakage during the whole process, avoiding pollution caused by electrolyte leakage.
