Control contact with disciplined preload and watch the water loop like a core process variable. Buy and operate to drawings with measured tolerances and traceable QC. In practice, verify drawings against your OEM pattern, set and record preload, track tons to the regrind threshold, and compare cost per ton across materials and coatings over multiple runs.
