I've been following this thread for a few years in the hopes that I would find an Interact 412 near me (central Indiana). One popped up on eBay last week (finally) and I got it for a very, very reasonable cost. $600! It was a running machine until recently. The owner just got tired of replacing encoders and decided to part with it. It is in very good condition, just dirty. The only thing that appears amiss is the right saddle needs some turcite replaced but can get by with it as-is. Needs a good pressure washing and repainting of the sheet metal components. I trailered it home Friday and now I have to figure out how to get the dang thing off the trailer. Gonna have to rent a big fork truck.
The plan is to gut the Heidenhain control, keep the Fanuc AC spindle drive, install 1kw AC servos, and integrate everything else with SSRs. I don't have three phase power so I am going to acquire a 10hp Phase Perfect. Right now my other Bridgeport running on Mach with a VFD runs perfectly on single phase, so this isn't my first rodeo but have other machines running on a rotary phase converter and I would really like to get rid of that dinosaur.
The door is kludged together at the top with a ball bearing drawer slide. Am investigating what was there originally.
Machine, right after loading it:
