I retrofit an induction heat treat machines that operates in exactly the same manner. The machine I worked on was made by Inductoheat.
I replaced the motion controller with a PC running Mach3 ( this was years ago.. before I saw the light.. ;-) ) I tied into the existing heater controls. Be careful how you run your wires. The induction heating circuits thrown off intense magnetic fields.
