Electrochemical processing of the reaction(Steel in aqueous solution with NaCl)First, the anode reactionN Fe-2e Fe + 2N Fe-3e Fe + 3N 4OH - 4e O2 ↑ + 2H2ON 2CL - 2e CL2 ↑N Fe + 2 + 2 OH - Fe (OH) 2 ↓ (dark green floc)The precipitate is 4Fe (OH) 2 + 2H2O + O2 4Fe (OH) 3 ↓? ? ? ? (Yellowish brown precipitate)Second, the cathode reaction (according to the possibility of)N 2H + 2e H2 ↑N Na ++ e Na ?.N According to the basic principle of the electrode reaction, the particles with the most positive electrode potential will react first at the cathode. Therefore, only hydrogen is precipitated on the cathode, and sodium can not be precipitated.During the electrochemical deburring process, the concentration of the electrochemical solution is gradually increased due to the decomposition and consumption of water, while the Cl- and Na + in the electrochemical solution only act as a conductor and are not consumed by themselves. Therefore, for NaCl electrolyte, Filtration clean, appropriate to add water, you can long-term use.N Tool can also be used for a long time.Second, the characteristics of electrochemical deburring(1) Deburring range? Electrochemical deburring for stainless steel, zinc alloy, aluminum products, titanium, copper, silver, gold, low carbon steel and other conductive material parts.? Such as: all kinds of valve, piston, cylinder casting and other auto parts, electrical appliances, computers, LED products, electronic digital accessories,? Precision molds and metal products industry.(2) can be a simple operation to remove all kinds of complex shape of the workpiece surface. And does not affect the workpiece(3) the surface quality is good? N no deburring and cutting heat during deburring, low surface roughness (Ra1.25 ~ 0.2μm) and ± 0.1mm average deburring accuracy can be achieved. Electrochemical fine deburring of steel can reach ± 10 ~ 70μm.? N suitable for removing deformable or thin-walled parts of the accuracy of burr.(4) Deburring tool electrode in the course
