It would cost alot to have an individual set CNC machined. You would have to pay for the material, a engineer to design the plates, a tool maker to make the tooling and fixtures, the tooling and fixtures themselves, the programer to write the CNC program, a set-up guy for the set-up, plus the actual machine time and machinest time, and the plating. Custom CNC billet is not cheap. I work in a machine shop and you should see some of the prices customers pay for simple little items. CNC is expensive! If you found someone good that can manually mill them it would cost alot less. The only reason billet seems cheap through places that specialize in it is because of volume. You also should see how much we charge a customer if you have to tear down a in process set-up just to machine them a piece or two.
