WAIT a MINUTE! He can do it with the existing equipment he
has, which is a 3-axis CNC mill! I got a little single-row thread
mill some time ago to do some odd internal threads. But, thread
milling can be done on outside threads, too. With a little program
to crank out the arcs, you can cut beautiful tapered threads in a
few seconds. If you need a couple of seconds to wipe off the
chips while it is doing the next one, it should be fine. With the
CNC milling of the threads, there's no technique to getting the
right depth each time. Also, with a suitable clamp to hold a bunch
of parts, he can line up the parts, and the machine can run down the
row tapping them all in a few minutes.
