The CSMIO sync's the Z axis to the rpm of the spindle whilst doing tapping and thus requires encoder feedback from the spindle to do that.
The Code for doing rigid tapping is normally G84 but as Mach itself only supports a pseaudo rigid tapping routine then the CSMIO does it external to Mach and you call it with a M84. It should be easy enough to edit the post processor for BobCAD to issue a M84 instead of a G84.
The motors you linked to should work well enough as they are servos. Just had a quick look but it seems 3000rpm is the max though. You could possibly get a larger servo and gear it via belt/pulley to give you the RPM, that is what I will be doing on my Chiron, currently the motor I have is only 3800rpm but I am gearing it 1:2.25 and thus will get 8550rpm.
