Re:CHNC-1 Retrofit & Upgrades

Rob, I am going to be retrofitting a older CHNC with ac servos an such, but need the get new pulleys and belts, where did you find those? Also I think I am going to be using Mesa cards. What cards did you end up using on this conversion?

thanks.

sorry john


I should have been more clear with my post as you can tell i sometimes go off on a tangent

when I get excited about something new.


no harm no foul

Thanks John

I did not get a chance to work on it last night

had to do the domestic thing.


I will do some more on it on saturday and fill you in on the state of things


thanks for all the help this week, I am really glad to be on this forum


Bob

where are you?
i am in UK john is in USA so not sure if my help on part locations would be helpfull or not

I am in USA (IOWA) but not opposed to ordering from overseas if needed but John did say that the parts are common from mc master carr

the company I work for has an account so ordering from there should not be a problem, I still need to do some troubleshooting to get the air solenoids

working just to test all of the air components, and I am going to do some preventative maintenance anyway.

Yes on the huge control cabinet, However I do not get any response when I turn the main power on at the

large enclosure that I would call the power in section. it has the main circuit disconnect and it is located at the tailstock end of the lathe

It is an HNC not CHNC. when I turn the power on at the controll I still get no response. What does IIRC stand for (if I recall correctly?)

I don't want to sound stupid but I am not very good at acronyms for electronics, so what are SSR's as well. when I plug in shop air to the connector I have

a hard core leak from the air solenoid cabinet on the lower front of the lathe, still have not been able to isolate this leak, will get back on it this weekend


Bob

I do have the wiring diagram for the HNC but it is all in acronyms so untill i learn what they are I am in deep

I do have extensive experience at reading electrical diagrams for automobiles but its been awhile since I really dug into

anything this complex.
