CNCCookbook: Epoxy Granite Fill
It'll be necessary to create a containment system so the epoxy grantie goes where you want it too and where you don't. That's been a real easy project for me using a combination of my Harbor Freight band saw and the 12" disc sander I built. Here are a few photos showing what I'm up …

Mineral Casting Machine Bed
Vibration also creates wear and tear on the machine. An epoxy granite CNC frame can reduce vibrations. It dampens them around 6 times faster than a cast-iron frame and 10 times faster than a steel frame. The machines make less noise. A mineral casting machine bed for tools like a milling machine or grinder makes the tool more accurate.

Initial diy cnc build questions | The Hobby-Machinist
If you do decide to build from scratch linear rails are the way to go IMHO. I've bought used ones from eBay quite reasonably. Look into epoxy granite for a base, you can weld one up like I did but getting it as flat as you like presents a challenge for even experienced welders. As for a combo machine look into running a 4th axis.

I have to send a cnc bench mill out the door to fit it but it's a small sace for a better more reliable, mechanically Sound milling machine. Hard to shake a stick at that.

Steel and epoxy are expensive, I'd think ceramic (tumbling stones, for instance) with higher speed-of-sound than steel, mixed with plaster of paris (soft, low speed of sound) would work well. Strength is NOT an issue, the column won't flex beyond the elastic limits of its fill.
