It's not so much what you can't do because almost anything can be achieved, given the right tooling for a mill. The limitations are a matter of what degree of accuracy can be achieved. A BP style knee mills is considered a graduated drill press for close tolerance work. They're fine for work that's +/- .0015 and location is a function of wear on the leadscrew or the limitation of the DRO and it's accuracy. There are good reasons for using a lathe, grinder, EDM, or jig bore instead of a mill. A mill is versatile but it's a matter of how well they'll do a given job.
