That's pretty cool, I haven't seen those before.

I think it's safe to say that the integrated servo units will be
serious $.

It does appear that the design has some potential for home
experimentation. I suspect that it would require a lot of toolpost
grinder use in order to get the tollerances that would be required.
You would likely have to grind the thread in pre-hardened material
since hardening after thread cutting would probably give too much
distortion.
