Well, what really happens is you find a new, better way to do things.
On a manual,
because it is hard to repeat an XY position, you center drill, drill
through, ream,
countersink and tap, all before moving to the next hole position. All
that spindle
start/stop and tool changing takes a LOT of time. On a CNC, you put in
the
center drill, and spot all the holes. Then you change tools, and drill
ALL the holes
through. Then, change again, etc. This actually can save a LOT of
time, making
some of these one-off jobs go TWICE as fast!

So, you might find that a Z axis can also speed up the one-off work,
once you
find the way to make it work for you.
