I posted a while back that I might be buying a Fadal mill and running
it from a phase converter. Well, I'm buying it. I'll write the check
tomorrow. It's a model VMC-15 and has rigid tapping so I guess I'll
need that parameter changing info. Also, just what is the advantage of
rigid tapping over tapping heads?
A big advantage for me is I can use combination drill-taps and be sure
they start the hole accurately without spotting, drilling, then tapping.
I have used a tapping head before, but it is a long stack out of the
spindle, and there is some free play in the tap holding end, so it
doesn't guarantee accurate positioning of the starting hole.

If this machine has an ATC, that may be less of a concern, although the
combo drill-taps are really fast if they suit your material thickness.
