I used to machine alot of different materials on "standard" metalcutting
machines, and what really makes the difference is your tooling selection.
I've had decent results using 2 fluted end mills (high helix) at about 1000 rpm
in various hardwoods. Straight fluted router bits , however chatter a great deal, but a bit of cut and try on RPM's vs feedrates will most likely get you
where you need to go.
