Abstract: A device for burnishing and smoothing metal parts, particularly suitable for use in mechanical-galvanic processes, comprising a main body having a fastening disc to which guides are radially coupled and the body of which includes at least three mobile propelling systems which are actuated by electro-mechanical means and move in a synchronized concentric manner, approaching and moving away from the central point and acting on a rotating frame from equidistant angles. The frame is configured to secure pieces to be treated and it also has a detachable head that is disposed centrally above a cylindrical tank. The propelling systems, provided with brushes, move from an open position in which they remain separate from one another and at a distance from the center, into a closed position in which they are joined to one another in the center of the tank, coming into contact with the structure containing the parts to be treated.

Abstract: The invention relates to a removable electro-mechanical device for burnishing and smoothing metal parts, said device comprising: a tank (2) containing an electrolytic solution and the cathode (c); a main body (3) which closes the tank (2), and in which the electrical contacts (6), the mechanical components and the drive systems (5) are incorporated, said drive systems being located in the lower portion of the main body (3) and being vertically and radially secured to a part (7) such that, in addition, when said body (3) is coupled to the tank (2), they remain immersed in the solution; and a detachable head (4) that can be coupled to the main body (3) and includes an electric motor (14) linked to a rotating body (15) and a removable, coupleable, rod-shaped supporting structure (41) or anode (a) having securing means (42) for the parts to be treated, and being disposed in such a way that, when said head (4) is coupled to the main body (3), the parts remain immersed in said solution.

Abstract: The invention relates to a device for burnishing and smoothing metal parts, particularly suitable for use in mechanical-galvanic processes, comprising a main body (3) having a securing disc (6) to which guides (7) are radially coupled and the body of which includes at least three mobile drive systems (5) which are actuated by electromechanical means and move in a synchronised concentric manner, approaching and moving away from the central point and acting on a rotating structure (41) from equidistant angles, said structure being centrally located and coupled in a detachable head (4) that is coupled centrally relative to, and above, a cylindrical tank (2). The drivers (5), provided with brushes (51), move from an open position in which they remain separate from one another and at a distance from the centre, into a closed position in which they are joined to one another in the centre of the tank (2), coming into contact with the structure (41) containing the parts to be treated.
