An assembly for electropolishing metal surfaces by means of particles of solid electrolytes in a gaseous environment. According to one embodiment the assembly includes a container and a housing element configured to house at least two metal parts, so as to contain the parts avoiding that they can go out during the electropolish process and at the same time allowing that they can have a given movement within the housing element and at the same time endow them with electrical connectivity by means of a first electrode and a second electrode that are coupled to an electrical source 3. The assembly also includes means to produce a relative movement between the particles of solid electrolytes and the at least two metal parts.
