hardinge hnc to retrofit

[lyfordln100]

Drew, I have a Hardinge CHNC that has a GE Control and I would like to retrofit with a Mach 3. Have you indeed retrofitted one of these?

Mine is a HNC late 70's I think and it has stepper motors now. If I had to do it over now digital servo controllers would be my choice. But eight years ago when I removed the servos that would have cost a mint. I think the CHNC is the same base machine wrapped up in a new package.

The HNC has a 5C collet spindle whereas the CHNC uses the larger 16C collets. Bar capacity is thus increased to (IIRC) 1.5" .
