    Preferably e! The means for holding the pieces include a rod and at least one clamp (jaws or conductive clamps, for example) for a piece and because the friction between the metal parts to be polished and the set of electrically conductive free solid bodies is caused by a movement Orbital of the pieces with respect to an axis.

    PREFERRED EMBODIMENT OF THE INVENTION
    In view of the described figure 1, and according to the numbering adopted therein, it can be seen how in a preferred embodiment the electropolishing apparatus comprises:
    • a tank (1) with at least one opening comprising an electrically conductive interior element that is configured as an anode or cathode depending on whether it is connected to a positive or negative electrical pole; suitable electrically conductive interior element to contact a set of electrically free solid bodies

    10

    30
    conductors arranged inside,
    • a fastening means (2) of the parts (4) with one or more fasteners (3) for metal parts (4), so that each fastener (3) connects the part (4) with the electric pole opposite to the electrically conductive interior element, and
    • means for producing a friction between the metal parts (4) to be polished and the set of electrically conductive free solid bodies.
    Preferably the clamping means (2) of the pieces (4) comprises a rod (9) and at least one clamp (3) for a piece (4) and because the friction between the metal parts (4) to be polished and the assembly of solid bodies Iibres electrically conductive is caused by an orbital movement of the pieces (4) with respect to the axis.
    In a more preferred aim embodiment, the orbital movement of the pieces (4) with respect to the axis is characterized in that it does not imply a variation of the orientation of the pieces (4) with respect to a reference point in the infinite. This embodiment has the technical effect of polishing in a homogeneous manner all sides of the piece except for the lower upper.
    In another preferred embodiment, not compatible with the previous embodiment, the orbital movement of the pieces (4) with respect to! axis is characterized in that it implies a variation of the orientation of the pieces (4) with respect to a reference point in the infinite. This embodiment benefits the polishing of certain sides of the piece, a beneficial circumstance in certain cases as in the case of the rings.
    In any of the embodiments described above, the electropolishing apparatus comprises an actuator that allows a movement to perform
    5
    10
    fifteen
    twenty
    25
    30
    a movement of rectilinear, alternative and perpendicular translation with respect to the piano of the orbit of the pieces (4) with respect to the Cuba (1). This movement allows the upper and lower sides of the piece to be polished (4).
    In any of the embodiments described above, the electropolishing apparatus comprises means for generating a vibration that causes a relative movement between electrically conductive free solid bodies. Said relative movement between electrically conductive free solid bodies that causes the frictional force between electrically conductive free solid bodies and metal parts (4) to be smaller and more homogeneous.
    The number of fasteners (3) will depend, among other factors, on the size of the pieces (4) to be polished and the complexity of their shape. If you have concavities or are very angular, it may be necessary to have fewer pieces (4) in each lot. Figure 2 shows six fasteners (3) as a particular example.
    The fastening means (2) and the Cuba (1) have a relative rotation and / or translation movement, cyclic to be able to make several passes, which can be produced by the displacement of the fastening means (2), as it is has been represented in the figures, or by the displacement of the tank (1).
    In the case shown in the figures, the apparatus has a support (5) of the mobile fastening means (2) for being located eccentrically on two cogwheels (6) which rotate in solidarity thanks to a belt (7).
    In this case, the pieces (4) perform an orbital movement with respect to the axis

    5
    10
    fifteen

    which does not imply a variation of their orientation with respect to a reference point in the infinitive. This movement is achieved by orbiting the pieces to be polished with respect to the axis and, simultaneously, by rotating them on themselves, in the opposite direction, parallel to the orbital axis and at the same frequency. The movement in the opposite direction of the rotation must be considered between the sprockets connected by the belt and the two axes that articulate the plate that supports the pieces to be polished.
    Likewise, in other embodiments not shown, the support (5) may correspond to an inner pihon in an internal or planetary gear. In another embodiment, also not shown, it is the tank (1) that moves because it is mounted on a support similar to that described.
    It may be interesting that the fastener (3) can rotate on a horizontal, or substantially horizontal, axis to choose the best orientation of the piece (4). This rotation can be manual, as the pieces (4) are installed in the fasteners (3), or automatic and simultaneous with the relative movement between the tank (1) and the clamping element (2).
    On the other hand, the clamping means (2) is composed of a vertical guide (8) and a mobile rod (9) on the guide (8) to be able to vary the height thereof. Thus, the height on the bottom of the tank (1) at which the pieces (4) are placed can be varied, or they can be removed from the tank (1). The rod (9) is therefore mobile on the guide (8), either manually or automatically by an actuator (10) (a hydraulic cylinder, a rack and pinion system, ...).
    For its part, the tank (1) is vibrating, for example by being arranged on a vibrating table (11). That table (11) can be supported on springs or elastic blocks (12), or other solutions, within the

    5
    10
    fifteen

    apparatus to avoid transmitting the vibration to the rest of the apparatus. The table (11) can vibrate by any known method, for example by comprising one or more eccentric elements (not shown) connected to a rotor (not shown).
    The whole apparatus is preferably inserted into a housing as a safety measure. For the same reason, the upper opening of the tank (1) may have a sealing gasket (not shown) that retains the electrolyte inside the tank, but allowing the passage of the fastener (2) and the parts (4) .
    In operation, the user enters in the tank (1) the necessary amount of electrolyte that carries the free conductive solid bodies. The electric current is switched on and the vibration of the tank (1) is started to facilitate a homogeneous contact between the pieces to be polished and the solid conductive bodies free. In parallel, the relative movement between the clamping element (2) and the tank (1) occurs to vary the position of the pieces (4) and polish its entire surface.
    Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field understands its scope and the advantages that derive from it, stating that, within its essentiality, it may be carried out in other modes of realization that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is required provided that it is not altered, changed or modified its fundamental principle .
