Yes, although it's pretty rare. Ground surfaces on machine tool ways are
best used with pressure oil systems. When you don't have oil pressure, it is
possible, with an exceptional grinding job, to get high friction.

The cure used in most machine tools is to "frost" the way surfaces, which is
a sort of after-the fact scraping job, usually done with a power scraper to
produce a decorative surface effect. You want it to be very shallow and you
aren't scraping to a standard here. You're just trying to reduce the bearing
area and leave some low areas (by millionths, not by tenths) to hold oil and
to reduce the contact area.

Final scraping called "frosting," or "flaking" is used for hand scraping of
ways for decoration (allegedly to hold oil), but would you want to use it after
final grinding (other than for decoration)?

If the surfaces here related "stuck" together dry (as Jo blocks) on wringing,
that would be one thing, but that's not the case so far related.
