Electropolishing systems ensure repeatable, micro-tolerance surface roughness finishing for industrial, medical device and aerospace metal parts. Stainless steel electropolishing systems produce a bright, corrosion-resistant, highly-polished surface, reducing the expense and surpassing the quality of standard mechanical polishing.

Electropolishing, like most surface treatments, requires proper surface preparation prior to the process, and also requires rinsing and other steps following the actual electropolishing process.

Typical systems include parts washing and rinsing stages prior to the electropolishing step, and multiple rinses as well as post-process acid dip. For example, one large-scale electropolish system utilizes the following process steps:

1. Clean
2. Rinse
3. Deoxidize
4. Rinse
5. Electropolish
6. Rinse
7. Rinse
8. Nitric acid passivation
9. Rinse
10. Rinse

Common applications for large-scale electropolishing systems

• Medical device stent polishing and deburring of stainless steel and cobalt chrome
• Industrial stainless steel 300 series polishing to reduce surface roughness and burr removal
• Reducing friction and ensuring top performance on flight-critical aerospace parts
