6061 aluminum part
I wanted to know the best way to put a nice shiny finish on my new part. I surfaced the part on my CNC mill, but don't like the boxed swirly pattern that the end mill left.
I don't own a surface grinder, but I do have a 12" disc sander and a 6" grinder. I have 120 grit paper for the 12", but don't think this is really going to leave me with a nice shiny finish.
Any tips or help would be greatly appreciated !!
Thanks
