I know of zero CNC machines that operate from a line cord.

Which demonstrates how little you know. I've worked with several CNC
machines intended for secondary operations that could be moved around
the shop as needed. All ran off a line cord.

"Lenin called them "useful idiots," those people living in
liberal democracies who by giving moral and material support
to a totalitarian ideology in effect were braiding the rope that
would hang them. Why people who enjoyed freedom and prosperity worked
passionately to destroy both is a fascinating question, one still with us
today. Now the useful idiots can be found in the chorus of appeasement,
reflexive anti-Americanism, and sentimental idealism trying to inhibit
the necessary responses to another freedom-hating ideology, radical Islam"

My Compact-5/CNC lathe (Emco Maier) operates from a line cord at
117 VAC (with jumpers inside for lots of other options since it was made
in Austria with exporting to many countries in mind.

Granted -- this is a small one -- 5" swing.

I was going to ask "When the cost of getting a permanently wired
lathe inspected is $1500, verses inspecting the same lathe with a
pigtail and a plug in for $500, which rout do you reckon the shop will
take?"

Heck, I know of houses being wired up with a big plug where the
house power would connect. Made the entire house "an appliance". EE
