I would like to hear from anyone that has done a retrofit on a Hardinge CHNC lathe using the original motors. I would like any notes you might have on how to do it. I am a novice as the handle implies so I can use all the help I can get. If there is anyone in the East Tennessee area that has done one I would like to see the machine and to talk to you to get ideas. There are a few pictures on the link that show the inside of my electrical cabinet. Thanks, Email is This email address is being protected from spambots. You need JavaScript enabled to view it..

Do the original controls work at all? Might help in tracing out circuits...

I think a good first step would be to search for, beg for, or borrow the machine drawings and the HI-AK servo drive info.

Also those drives look pretty ancient, if you are handy with a soldering iron, replacing the electrolytic capacitors would not be a bad idea...

I used Jon's PWM amps on my HNC:

I sent my left over amps to Jeff or Chris, so at least one person knows how to get them working. I believe the resolvers where use too. Check with Jon at pico-systems.com/motion.html

I may still have the manual and schematics or I may have sent those too. I can look if needed.
