I have a big stationary vertical drill if that
is what you mean by "milling machine", so then
it is just a matter of getting the round
saw/drill thing (?) and some sort of
arrangement to fixate the tube?

To answer your question. No a drill press is not a vertical milling
machine :-(

But yes, you could use a drill press with a hole saw to miter the end
of a tube. Alignment might present a problem but can be overcome.

On the other hand if you know how to file it might even be quicker,
for one tube end, to simply mark the tube and file to shape.

There is a very old application called "Tubemiter.exe" that has been
around for years and years that given tube diameters and joining angle
will print out a template that you can wrap around a tube to mark the
actual cut.
