What is Electropolishing?

Electropolishing is a very effective way to polish metals. Electropolishing, sometimes referred to or also known as electroplating, involves immersing a peice of metal in a liquid container of electrolytes and sending an electric current through the bath. The result is that a very thin layer of metal, almost a microscopic layer, is removed from the desired project. The bath container is connected to the positive terminal of a DC power supply. The negative terminal is connected to a cathode, which is basically a container (like a tube or cylinder as in a battery) that attracts and stores electrons. Current is then run through the system, in which particles from the metal piece are removed because they are attracted to the cathode. A higher or lower level of polish can be achieved by adjusting the current and the size and distance of the cathode from the work piece. After an elctropolishing bath, the metal is cleanly and almost perfectly polished.
