Stock Removal During Electropolishing

Often the last step in the manufacturing process, electropolishing is a “reverse plating” process that removes the outer skin of metal instead of depositing metal on the surface. . The process removes a uniform layer of metal from parts’ surface to remove surface defects. Using a combination of chemicals and electrical current, electropolishing carefully removes surface imperfections and contaminants from metal parts removing as little as .0002”” up to .003”” (.0001” to .0015” per surface) to produce the desired surface finish

Electropolishing Sharp Edges

Manufactured parts, whether through stamping, laser cutting, or grinding, often have resulting sharp edges that need to be properly treated before they can be used in their final application

Electropolishing, often the final step in the manufacturing process, can effectively treat sharp edges to achieve the proper finish. Because electropolishing can be used with almost any alloy, including specialty alloys like Nitinol and titanium, it is a preferred finishing method for part engineers and manufacturers.

Whether the final, desired edge is sharp or dull, electropolishing can achieve the desired finish on even the most fragile parts.

How to Specify Electropolishing

Mar 11, 2016 4:48:30 PM

Electropolishing is used to improve surface finish and corrosion resistance, enabling parts to perform better and last longer. While there is no unified standard on how to specify electropolishing, there are some best practices that engineers and manufacturers can use to ensure the final finish on their parts meets their specific requirements.
