A " daimeter Ball Mill with a stepover of .035 will give between a 125 and 200 micro finish. This is pretty broad, but it's fairly accurate. This part would need polishing. ;) I skipped this part earlier. There again it all depends on what you are making and the tolerance you have to hold.

Keep a low cut width (or cut depth if you're talking the floor of a pocket or surfacing with a Face Mill) and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 23x chip load will be right for the finish pass.
