What is Passivation? How Does Stainless Passivation Work? - Best Technology

Passivation is a widely-used metal finishing process to prevent corrosion. In stainless steel, the passivation process uses nitric acid or citric acid to remove free iron from the surface. The chemical treatment leads to a protective oxide layer, or passivation film, that is less likely to chemically react with air and cause corrosion.

Machine spindle runout - Practical Machinist

If your spindle is truly running out, then the ecentric wobble of the spindle will be reproduced in the turned diameters. Obviously this eats up your tolerance. If you are turning to a 0.001" tolerance, runout of 0.0005" would eat up half of your tolerance. In a milling machine spindle run out causes the cutter to run out and cut unevenly.
