Electropolishing offers various advantages for vacuum components, such as enhanced cleanliness, prolonged component life, and improved aesthetic quality. However, it cannot achieve exceptionally smooth surface finishes on its own or drastically improve pump-down time.

To decide whether to electropolish your vacuum component, consider factors like the need for sterilization, the operating environment, aesthetics, and concerns about water vapor affecting the vacuum level. If these factors are critical, electropolishing may be worthwhile, but if not, a glass-bead-blasted or machine-polished finish could save time and money.
