Components with a pre-process roughness of Ra 0.5^m (Rz 2.4^m) can be improved to about Ra 0.08^m (Rz 0.4^m).

By using a lapping film with a #2000 grain (9^m), surface roughness can be even further improved beyond level I and level H

Components with a pre-process roughness of Ra 0.5^m (Rz 2.4^m) can have their finished surface roughness improved to Ra 0.04^m (Rz 0.2^m).
