The paper presents results of the research aiming to check if and how material structure affects surface roughness in electrochemical process nanofinishing. Piece of aluminium alloy AA 1200 after severe plastic deformation have been prepared in automatic roll bonding manner. Various level of deformation has been implemented, what resulted in various level of material granularity. Severe plastic deformation gives possibility to obtain nanometric grain sizes. Electrochemical polishing was carried in 15% NaNO3 electrolyte under various voltage conditions. The experimental results proved that electrochemical machining is satisfying method for such a especially prepared material smoothing. The surface roughness significantly depends on the reactions appearing on phase boundary, which is between the electrolyte and machined material. It was shown, that material structure strongly affects results of material smoothing with use of electrochemical machining. Small grain size makes material much isotropic, thus electrochemical dissolution is more effective and make it possible to reach surface roughness parameters values in nanometric scale.
