That is pretty much the conclusion I came to, CF has been used for CNC machines but only in the ultra high precision ones and I'm guessing the thermal expansion of steel and it's momentum put the CF ahead in those situations. For the size of those machines the labour cost is probably far higher than the cost difference in raw materials.
