It can support SIX axis's and yes it can support Rigid Tapping but it is a option you have to buy and you have to get some encoders on the spindle

here's a blurb from thier website

"This option frees you from the cumbersome and sometimes inaccurate methods of tapping with floating and reversing tapping heads. You not only get standard rigid tapping, but also have the option of rigid peck tapping. Both the Spindle "S" function option and a spindle-mounted encoder are necessary for rigid tapping. Rigid Tapping $495

By the end of all this crap I'll be a BP interact series II guru
