Electropolishing has a leveling effect on sharp edges, ridges, light scratches, & burrs.
Electropolishing is ideally suited for processing parts in quantity to produce uniform size or weight.
The microfinish is improved by a factor of 2 (20 Ra is reduced to 10 Ra).
Cracks and other surface defects that act as stress-concentration sites are removed, improving the fatigue strength.
This applies particularly to springs. Tests have shown fatigue life to be greatly increased after treatment.
And electropolishing is super passivation. Parts have a smoother, cleaner, brighter, chrome-enriched surface. All surface impurities such as scale, rust, foreign debris, oils, grinding compounds, hydrogen, carbon compounds, iron and other materials are removed.
Parts that benefit from electropolishing:
Boating and Marine products
Railings, Structural forms and plumbing
Dairy and Pharmaceutical filtering components
Automobile and Motorcycle decorative parts
Nut's and Bolts
Plus many more
