Today's Milling Lessons

When edge milling acetal with a coarse mill, I get a pretty smooth finish, but seldom better than .01" accuracy.  Face milling produces a rough finish.  Edge milling with a fine mill, gives a series of ridges.  Face milling with the fine mill gives a glassy smooth finish and better accuracy.

I have taken to using the coarse mill to get within .01" then fine mill to get to a nicer more accurate dimension.
