Many industrial merits are found in electro-chemical machining of metals as compared with other conventional methods of metal working though the accuracy of the worked piece by electro- chemical machining is not very satisfactory.The author investigated anodic dissolution, working condition, and workability of removing iron in electro-chemical machining and the following experimental results were obtained:(1) Electro-chemical machining of iron could be successfully performed when halogen compounds were used for electrolyte.(2) The accuracy of worked piece was variant depending on distance between electrodes, nature of electrolyte and chemical composition and microstructure of working material.Electro-chemical machining of irons of almost same composition in sodium chloride solution gave variable results of anodic polarization potential depending upon the microstructure of working material.When anodic polarization potential was lower, both current efficiency and penetration rate were higher and also the removing was more effective.
