Re: Small Concrete CNC Mill. Juan .. Your numbers are way off base. The best manufacturers in the world are not getting 1/3 of the stiffness your numbers suggest. A typical max load on a mill of 2 HP, bridgeport territory, is around 40 kgf. 400 N. This will deflect about 0.1 mm on a bridgeport table, at the edge.
