Mechanical Polishing, Deburring, Electropolishing, & Passivation Services

Finishing Capabilities

Olympic Systems specializes in mechanical polishing, deburring, electropolishing and passivation processes. Our finishing services are utilized by a diverse range of industries. For example, the semiconductor industry utilizes our high purity electropolishing, cleaning and certified Class 7 clean room for packaging and the pharmaceutical and biotechnology industries utilize our mechanical polishing, electropolishing and passivation processes for components and manufacturing equipment.

Our finishing services are applied to a wide range of materials, from stainless steel to exotic metals (titanium, Hastelloy, duplex and AL6XN), aluminum and plastics.

Mechanical Polishing / Deburring

Mechanical polishing is the smoothing of a metal or plastic surface using mechanical tools and abrasives. Deburring is the removal of raised particles and shavings that appear when metal or plastics materials are machined.

Benefits of Mechanical Polishing / Deburring:

  • Improves surface finish and cleanability
  • Improves aesthetic appeal
  • Reduces product adherence


Passivation is a treatment of stainless steel with a mild oxidant that is intended to remove free iron and foreign matter. At Olympic Systems we passivate using our citric acid process.

Benefits of Passivation:

  • Improves corrosion resistance by forming a corrosion-resistant passive layer on the surface
  • Eliminates the free iron corrosion potential


Electropolishing is an electrochemical process by which surface material is removed by an anodic dissolution. During our electropolish process we can achieve a 3 Ra surface finish without compromising dimensional properties. We are capable of electropolishing and passivating AL6XN and 300 and 400 series stainless steel.

Benefits of Electropolishing:

  • Smoother surface
  • Dissolves burrs
  • Less reactive
  • Reduces the adherence of contaminants
  • Improves surface corrosion-resistant surfaces
  • Allows product to be more easily sanitized
  • Reduces the build-up of some bacterial biofilms
