The Difference between Mechanical Polishing and Electropolishing

Mechanical Polishing: Traditional Techniques

Mechanical polishing is a conventional method employed to refine metal surfaces. This technique involves abrasives, buffing wheels, or abrasive belts to remove surface imperfections, scratches, and blemishes. Through physical force and friction, the surface is smoothed, achieving a relatively polished appearance.

While mechanical polishing has been widely used and is effective to some extent, it has limitations. One significant drawback is the tendency to embed abrasive particles into the metal surface, potentially causing contamination or corrosion initiation points over time. Moreover, it might not uniformly treat intricate or hard-to-reach areas, leading to uneven finishes.

Electropolishing: Precision Redefined

On the contrary, electropolishing is an advanced electrochemical process that doesn’t rely on abrasive tools. Instead, it involves the immersion of stainless-steel components in an electrolyte bath while applying a controlled electrical current. This process selectively dissolves microscopic surface irregularities, leaving the material with a smooth, clean, and bright finish.

Electropolishing offers a plethora of advantages over mechanical polishing. Firstly, it’s highly effective in deburring and polishing intricate or complex shapes. Secondly, it removes a controlled amount of surface material, reducing microscopic peaks and valleys, which in turn improves corrosion resistance and fatigue life of the metal. Furthermore, electropolishing eliminates embedded contaminants and imparts a passive layer, enhancing the material’s biocompatibility in medical or pharmaceutical applications. Finally it is cost effective and more economical way to finish stainless steel versus mechanical finishing.
