| description | The method comprises introducing the metal parts on a rotary structure (3) provided with a receiving unit (15) and rotatably mounted about a horizontal shaft (5) inside a treatment tank (1); establishing potential differences between the parts and a set of electrodes arranged in the tank, where the parts are supplied with current of polarity opposite to that of the electrode via the receiving unit and the rotary structure; and submerging the parts completely in treatment liquid in the tank by rotational movement of the structure bringing the parts successively to face the electrodes. The method comprises introducing the metal parts on a rotary structure (3) provided with a receiving unit (15) and rotatably mounted about a horizontal shaft (5) inside a treatment tank (1); establishing potential differences between the parts and a set of electrodes arranged in the treatment tank, where the parts are supplied with current of polarity opposite to that of the electrode via the receiving unit and the rotary structure; and submerging the parts completely in treatment liquid in the tank by rotational movement of the rotary structure bringing the parts successively to face the electrodes. The electrodes are arranged in respective compartments (6, 7) of the tank. The method further comprises: determining number of metal parts previously placed on a support including a holding member for immobilizing each of the parts relative to the support; introducing the support into an immersion area arranged in an upper part of a tank for processing, where the support is housed on the rotary structure; driving the support to a rotational movement of 360[deg] C; introducing the support to an exit zone arranged in the upper portion of the tank; removing the support from the tank; continuously carrying out the process by rhythmic displacement; and marking downtime of the rotary structure when the support is placed opposite to the electrode. The method is carried by controlling spatial distribution of the electric field between the electrodes and the metal parts. Independent claims are included for: (1) a method for liquid surface treatment of parts; and (2) a machine for surface treatment of metal parts.
