Silyavski bet me too it and i was going to say same.

You can find Old machines like that Bridgeport that just need new life breathing into them.
You don't waste your time trying to use there old standard controllers just rip them out and retrofit with modern one. Often there control on these things are limited with very little memory.
You'll find on older machines the drives will require 0-10v analog signals rather than step & dir like modern stuff uses.
Ounce upon a time this made life difficult for your average person to retrofit or Very very expensive after market controllers so often things like drives and motors where replaced making it expensive and uneconomical in some cases.!! . . But not anymore now Cslabs have a analog Controller at sensible enough money that was designed just this purpose of retro fittng old machines. Even ones that use 12 or 24 logic.!

This means often all you need to replace is the Controller and with a bit of re-wiring you can re-use all the existing components and get the machine working like it's never done before.!
Just be aware thou most industrial spec machines require 3 phase power.! Often this is just for the Spindle not the Motors or drives. On many old machines like that Bridge port you'll find either Steppers or Brushed DC servos. Depending on drives etc often it just means changing or rewiring a transfomer so use single phase.
The Spindle is the main thing that will require 3 phase but often you can just run these straight from a VFD. Or you can buy Converter that will transform single phase to three phase if large HP.

Personally I'd wait for some Old iron to come along and replace everything with moderern servos and controller etc before buy those mickey mouse toys.
