It is most strongly recommended that you do not lap the ways of lathes and
mills.

If the flatness obtained from the surface grinder on a hardened way is
insufficient and if you have the use of an autocollimator and if you are
working in microns or less, then you might consider lapping. Otherwise, use
scraping or surface grinding.
