It may be able to do a lot, but with those long unsupported rods it won't be a very effective CNC mill. People seem to think that all they need to do is to put a spindle on their 3D printer to turn it into a mill, but that's not the case - rotary cutting operations cause a lot of vibration, which if the machine isn't rigid, will cause the cutting head to bounce around instead of cutting smoothly. The harder the material being cut, the more rigid it needs to be. This machine might be able to cut cake - anything tougher, not so much...
