I will only ever need to pocket out say 50mm thick Ali, or brass, woodwork and some intricate designs for electronic enclosures, microphone designs .Not in a high production capacity either, so finish more important than speed. I have spec'ed out the components for what I think will result in a build envelope of 290 x220 x 60 in z, which im hoping will be more than capable for my immediate requirements (and will have inherent value)


I want to check that i'm not going over board for such a small design that only needs modest soft metal cutting. To use 50x25 Ali box section (any recommendations on uk supply?) and essentially have similar design, guides to the red design in this post, only smaller footprint. Also the omio cncs seem quite capable although still larger than I need
Ok it's late and I'm tired so will make this replay short but ask me if want to know more.

Your idea of a machine to cut 50mm deep in Ali, brass etc and give high quality finish doesn't fit with your suggested build materials, 50x25mm Ali box section is just not stiff enough cutting Ali and giving high quality finish.
You need much stronger machine that won't resonate if you want a high quality finish. Thick walled steel is the best way to go.
