How to achieve a mirror finish on stainless steel?

To achieve a mirror finish on stainless steel workpieces, polishing generally involves three steps: rough polishing, medium polishing, and fine polishing.

Rough polishing, also known as "roughing," primarily utilizes the physicochemical interaction between a hard grinding disc in a polishing machine and a stainless steel polishing slurry (rough polishing slurry) to achieve a relatively uniform surface smoothness.

Medium polishing typically uses polishing pads of moderate hardness and stainless steel polishing slurry with smaller abrasive particles (medium polishing slurry) to refine the rough polishing lines. The abrasive particle size affects the polishing rate and the mirror finish.

Fine polishing: To achieve a superior mirror finish and smoothness, stainless steel workpieces require fine polishing. We use softer fine polishing pads and nano-polishing slurry for further deep polishing to achieve the customer's desired mirror finish RA value.

Our company has professional stainless steel polishing slurry formulas and products that achieve a mirror finish by removing burrs, pitting, and scratches, with an RA value below 0.009μm. For more case studies and products, please contact us.
