.05-.2 microns? Zoiks!
ANSI/CAMI 2000 grit is ~15,000-ish mesh. That's about 1 micron.
This burnisher produces a finish comparable to a mesh of over 100,000.
You can get abrasives lower than that, but wow. That's mighty smooth.
But again, is this the method used for stainless?
No. Stainless would wear out the rollers in a burnishing tool very quickly. You could maybe make a couple of barrels before needing to rebuild the tool. The cost would be astronomical.
