<p>The invention concerns an electrochemical processing device used to bore different metals by means of a hollow cylindrical electrode.According to the invention, the electrochemical processing device consists of a rotary hydraulic engine that operates a lead screw, through some worm-spiral gear and a cogged gear. The lead screw is screwed into a nut mounted on the electrochemical processing device. A case linked to the lead screw moves axially from the nut.The rotary hydraulic engine, mounted on a case, ensures the rotation movement of the hollow cylindrical electrode.</p> |
