At least the lathe isn't running punch tape.
Don't upgrade or mess with the control. Disconnect from the network if it's on it. It should have RS-232. Throw a Pi or other SBC that does serial and a 12V level shifter; use that to feed it programs.

I won't touch the DOS software it uses to actually run the plant, the lads can have at that.
