Thoughts:

80 mm is way more than you can do in one pass but you already knew that.

If you're having surface finish issues, how rigid is your setup?

Are you using carbide or hss? Carbide is stiffer but it does require
the setup on the machine to be more rigid. Larger diameter cutters
are more rigid than small ones.

Are you using reasonable speeds and feed for the cutters in use?
A 1/4 inch carbide cutter needs higher speed for optimum cutting than a Bridgeport style machine can provide.
