New Invention: Mobile equipment for electrochemical machining and polishing aided by ultrasonics

Inventors from Romania presented at the International Exhibition of Inventions of Geneva 2014 the invention: “Mobile equipment for electrochemical machining and polishing aided by ultrasonics”.


The invention includes:


  • Ultrasonic aiding of electrochemical machining using an electrode-tool positioned at the end of an ultrasonic chain and electrolyte liquid supplying through a nozzle located in nodal point;
  • Ultrasonic aiding of electrochemical polishing using a rotary electrode-tool and a hopper supplied with electrolyte liquid on which an ultrasonic transducer is assembled;
  • Ultrasonic removal of passivated layer works when polishing by tool rotation stops.




  • Electrochemical machining complex surfaces of workpieces with overall great dimensions located indoor and outdoor;
  • Efficient removal of passivated layer by ultrasonic aiding, increasing process stability and machining rate without supplying with high pressure of electrolyte liquid;
  • Uniform circulation of electrolyte liquid on machined surface using rotary electrode-tool, decreasing surface roughness.


This invention has a potential for broad international application. The inventors are interested in commercialization of their invention, for which an application for patenting has been submitted, and are seeking appropriate interested manufacturer. European Patent Registration and Consulting Services GmbH has made direct contact with the inventors and has access to information about the invention directly from the inventors.
