Re:Hardinge CHNC 1 Lathe

Well I started the conversion of the Hardinge to EMC. The first thing I'm doing is building in a phase converter and putting the work light on a circuit that is not dependent on the controller LOL. I have a freebee 10hp motor for the phase converter and I just traded a propane heater for at 15 hp motor so I'll have to see what works out best for me. Some interesting things I found out is the turrent has a "encoder" as called out in the prints, but it is really a bcd board to indicate the position of the the tool turrent. RobH used the weighted_sum to convert the bcd to a number for the ladder logic to control the tool turrent.

More when I get time.

Well I finally got something done. The 10hp phase converter motor is installed on it's isolation mounts.

John, Are the original cards functional? What are you doing with them?

nice one john,
it will soon be zipping along then.

did you get spindle going yet?

rob

tenaja,

One card is bad the rest seem to be ok. Are you looking for one?

Robh,

Hi, not yet... I scratched my head for some time trying to figure out how and where I wanted to mount the 10hp phase converter. I hope to have the phase converter up and going by the weekend.

John

I have a CHNC that has a bad card. I was thinking of converting it when I saw your post... PM me if you are open to sending them off.

Have you got it running yet?
