Deburring

Why Electropolishing Works So Well for Deburring

Electropolishing isn’t just for making metal parts shiny it’s also excellent for deburring. One of the reasons it’s so effective is because of how the process works: metal ions are removed most rapidly from edges and corners. These are the same spots where burrs typically form. Just like lightning is drawn to tall trees or buildings, the electrical current used in electropolishing is naturally concentrated at the high points of a metal surface. So while electroplating adds material to these areas, electropolishing being the reverse removes it, making it a great tool for precision burr removal.

How It Stands Out from Traditional Deburring Methods

Electropolishing is especially useful when dealing with parts that are too delicate or complex for standard mechanical deburring methods like tumbling or vibratory finishing. It’s ideal for components with burrs from fine blanking, milling, broaching, lapping, or grinding. 

Another big advantage? The hardness of the material doesn’t matter. Whether the part is fully annealed or hardened, electropolishing works just as well. That’s why it’s often the final step in the finishing process, especially after all fabrication and heat treating is done.

And because it’s a non-mechanical process, there’s no risk of damaging the part’s surface. Delicate pieces with fine finishes or thin walls can be polished without worry. There’s no tumbling, no media hitting the surface, no scratches—just a smooth, controlled finish with no distortion or warping.

A Note on Larger Burrs

That said, electropolishing does have its limits. If a part has large burrs like those left over from rough milling or aggressive drilling those may need to be handled with a different method first. Electropolishing works best when it’s removing finer burrs or finishing up after initial deburring. Also, burrs caused by dull tools or poorly maintained dies (known as die break burrs) can be especially tough to remove without some pre-treatment.

Stainless Steel Deburring Made Easy

Got stainless steel parts with unwanted burrs or excess material? Able Electropolishing has the solution. Since 1954, we’ve specialized in precision deburring through our proprietary electropolishing process also known as reverse plating. Our experienced technicians are committed to delivering cost-effective, reliable deburring for stainless steel and a wide range of other metal alloys.

Even the hardest-to-reach areas of your stainless parts can be cleaned up with our process, and we do it all without compromising the structural integrity or strength of the components.

How Electropolishing Targets Burrs

During electropolishing, metal is removed most aggressively from edges and corners—the exact places burrs are likely to form. That’s because the electrical current naturally concentrates at high points, similar to how lightning is drawn to tall objects. While electroplating adds material to these areas, electropolishing removes it, making it perfect for precision burr removal.

Why Choose Electropolishing for Stainless Steel Deburring?

Electropolishing offers several advantages, especially for intricate or delicate parts that can’t handle traditional mechanical methods like tumbling or vibratory finishing. Because the process is non-mechanical, it works equally well on hardened or soft metals hardness doesn’t affect performance.

Also, unlike mechanical deburring, electropolishing doesn’t stress or distort parts. Your components won’t be scratched, dented, or damaged by abrasive media or by hitting other parts during processing. It’s a clean, stress-free solution for finishing metal surfaces.
