93 and 94 will be DC, the 95, I believe could be either, although I a have only seen AC 95's
I believe this is BS.Some say Fadals with vh65's arent a true 4th axis
Yes I can do simult XYZA (although I don't know where you would).
AFAIK the VH65 is DC and a VH165 would be AC.
this is also a "must know" http://www.compumachine.com/Support/...otary_Axes.pdf
