Isotropic Micro Polishing

Isotropic Micro Polishing

Millennium Technologies is proud to add Isotropic Micro Polishing to our line of performance services. Isotropic Micro Polishing is a surface treatment for ferrous (steel) parts that will reduce friction, increase durability, and increased effective film thickness (lubrication). Parts such as transmissions, cams, buckets, springs, and crankshafts will last longer, run cooler, with less friction and ultimately make more power.

Isotropic means having uniform physical properties in all directions. Our Isotropic Micro Polishing ensures the part's surface will have no visible marks, lines or patterns.

The Millennium Isotropic Micro Polishing process involves a chemical interaction that forms a soft, thin (less than .001mm) film on the surface of the part. The part is then vibrated in a special tub with a non-abrasive ceramic media. The film is physically removed from the peaks of the processed part while the valleys are unaffected. The film then re-forms at the peaks that are interacting with the vibratory media. This process of film re-formation and removal repeats itself until the peaks are gone and only the valleys are left. The result is a smooth micro-finish. The second step in the process is referred to as burnishing. During this step, all of the remaining conversion film is removed from the surface of the part, leaving a polished, chrome-like appearance.

The Millennium Technologies Isotropic Micro Polishing benefits are:

• Reduced surface stress
• Reduced friction, vibration and noise
• Longer component life
• Reduction in lubrication temperature
• Increased heat transfer
• Mirror-like finish
