I agree totally with Black Talon on the superiority of CNC machining.
I used to have to hold tolerances on machined parts (as close as .0002") on conventional "old style" machines, and did the same on CNC machines. It was a stressful adventure on the first group, I (or you, if it was set up and you can push a button) could do it with boring regularity on the CNCs, and the finish using coated carbide inserts and TiCN inserts wasn't even close. Neither was the economics. I once had to do the same job using conventional tooling and a Haas CNC milling center with the appropriate cutting tools. The first way took nine minutes and thirty seconds per profile, the second took one minute, ten seconds. Surface finish was between 125 and 250 with the non CNC machine, it was about 62 with the CNC.
CNCs are also able to do mix and match directions of cutting in all directions (is plural of axis axes?), so one can cut radii (curves), angles, steps, and all sorts of odd shapes on parts that used to take a special step or steps with a special tool.
The only thing CNCs can't do is care about the final product. That still takes a human to care enough to keep his parts in tolerance and not throw a bad one in the pile to make rate or keep his numbers up, regardless of what machine he is running.
If you don't already know it, the advent of CNC machining has revolutionized the gun industry, same as electricity and the invention of steel.
