Deburring of metal pipes. Manual deburring: The traditional methods of manual deburring are steel files, sandpaper, and grinding head grinding; and the trimming knife gradually replaces these traditional methods, which is simple and convenient to use, does not require technical processing, saves costs and is environmentally friendly. Electrochemical deburring: Electrolytic deburring equipment uses the principle of electrochemical reaction to automatically and selectively deburr parts made of metal materials. It can be widely used in the deburring processing of pump bodies, valve bodies, connecting rods, plunger needle valve couplers and other parts of different metal materials in pneumatic, hydraulic, engineering machinery, nozzle oil pumps, automobiles, engines and other industries. Ideal for hard-to-remove internal burrs, heat-treated and finished parts. Electrolytic deburring: Electrolytic deburring machine tool is an electrolytic machining method that uses electrolysis to remove burrs from metal parts, abbreviated as ECD in English. The tool cathode (usually brass) is fixed and placed near the burr part of the workpiece, and the two are separated by a certain gap (usually 0.3 to 1 mm). The conductive part of the tool cathode is aligned with the edge of the burr, and the other surfaces are covered with an insulating layer, so that the electrolysis is concentrated on the burr part. During processing, the tool cathode is connected to the negative pole of the DC power supply, and the workpiece is connected to the positive pole of the DC power supply. A low-pressure electrolyte (usually sodium nitrate or sodium chlorate aqueous solution) with a pressure of 0.1 to 0.3 MPa flows between the workpiece and the cathode. When the DC power supply is turned on, the burr will be removed by anode dissolution and taken away by the electrolyte.
