Benefits of Electropolishing
With microscopic precision and consistency, electropolishing provides unmatched metal finishing results. By removing a precise layer of surface material, electropolishing leaves critical metal parts ultrasmooth and free of burrs, microcracks and surface defects left behind by machining processes.
Suitable for a wide range of metal alloys, electropolishing is specified by engineers in the world’s most demanding industries, from medical device manufacturing, to aerospace, to food and beverage manufacturing, and semiconductors – among others.
In addition to the high-quality surface finish, electropolishing provides a range of other benefits, leaving parts with improved fit, finish and function.
DEBURRING
Electropolishing is an effective process for deburring metal parts. Because electropolishing removes surface metal from a part, it eliminates burrs on the surface, as well. This process is frequently used for deburring delicate or intricate parts, and it is effective on a variety of metals regardless of their hardness.
IMPROVED CORROSION RESISTANCE
By eliminating surface imperfections and contaminants embedded in a metal part’s surface, electropolishing significantly improves long-term corrosion resistance. In salt spray testing, electropolished metal parts benefited from higher corrosion resistance than raw and passivated parts.
ULTRACLEANING
Electropolishing removes surface metal and imbedded scale, rust, grinding compounds, foreign debris, and oils, creating a bright, uniform finish that does not peel or abrade. This finish increases corrosion resistance and improves weldability without affecting surface hardness or introducing stresses to parts.
MICROFINISH IMPROVEMENT
Electropolishing improves microfinish values even on complex or fragile parts that are not well-suited for methods like grinding, lapping or harperizing. It reduces the microscopic peaks caused by metalworking operations like stamping, welding, and forming, reducing microfinish values and improving part performance.
FATIGUE LIFE IMPROVEMENT
Electropolishing has become a common metal finishing process used to help improve the life of metal parts that flex, cycle, twist and bend. By removing surface imperfections on the surface of metal parts, engineers have found electropolishing to greatly improve the life of components that function as springs.
CONTROL
The ability to establish precise removal specifications is a key benefit of Able’s electropolishing processes. Our sample electropolishing process works to determine the optimal level of stock removal and other process requirements for achieving the desired result. Depending on the application, Able can control our material removal process to as little as +/-.0001” per surface.
