I do maple on a Matsuura VMC on a regular basis (some kind of helicopter
part). Generally run no faster than 3000 rpm to prevent burn marks. The
largest cutter I use is a 1.25 inch 6 flute. Run that one at about 2000.
Spindle speed is of little importance. Feed rate is everything. Never having
been around a CNC router, I don't have any idea what kind of feed rates you
guys run. Can't imagine it would be fast enough to have a reasonably heavy
chip load.

I have two CNC routers in my shop - and haven't ever used a CNC
milling machine for wood - but would guess that 3000 RPM would be a
marginal spindle speed even with 4-fluted cutters. I'd suggest trying
it out before spending your money.

On the other hand, you can probably build your own CNC router for wood
and plastic (and occasional use for aluminum and brass) for much less
than you can buy most used milling machines. There's a link below to
pictures of a small machine that I built in my shop...
