In the commercial world, most all heavy-duty metal-cutting CNC gantry routers use cast iron in their construction. Most commercial woodworking CNC gantry routers use steel tube and even aluminum components. While they can also cut aluminum, they are not intended for doing so on a production scale and their spindles are not designed as such or have as much power.

The hardest material I expect to cut will be red oak and most of the time The machine will see Baltic birch or apple ply.

Your response took a lot of time and effort.

I appreciate that a lot

Thanks.
