A machine that will cut metal will cut wood just fine. You could hang a router on the spindle or just use the main spindle at reduced feed rates. I use router bits in my main spindle when cutting wood (I also use carbide tipped router bits for machining all metals as the need arises)
Here are a few pics of milling some MDF. I built a dust control adapter that clamps onto the spindle and hooks up to my shop vac.
This is a gear case mockup to test the fit and confirm the tool path before I carved up a rather expensive chunk of aluminum. Using a 1/2 inch carbide tipped router bit.
