CNC lathes and mills don't take that much skill...as with 3D printing all you need these days is a model. upload to the control of the machine pick a few tool paths and you are away!!! modern CNC has very little difference to that of 3D Printing..i know this as I am an engineer who uses high end machines on a daily basis, and who has a cheap CNC lath/mill in his garage that didn't cost that much more than my UM2! the enabler is 3D model availablily. the skill is in the design of the item to be made..
