Electropolishing is an electrochemical process opp. to electroplating used machinery are same. The electro polishing process smoothes and streamlines the microscopic surface of a metal object. As result the surface of the metal is microscopically featureless.

Electropolishing will remove hydrogen from the surface of the part making it difficult for bacteria to grow.

Electropolishing is often referred to as a "reverse plating" process. electrochemical in nature, electropolishing uses a combination of rectified current and a blended chemical electrolyte bath to remove flaws from the surface of a metal part.

There are two types of Electropolishing facility.

• Direct electropolishing
• Electropolishing after mechanical polishing
