I'm thinking of taking on a Hardinge HNC retrofit. Has any one had success with one of these lathes? By success I mean capable of running commercial quality parts time after time as well as threading. Given the small parts these lathe are fit for I figure it would have to be rock solid and fast. I have retro-fitted two Bridgeport Boss Mills, but they were more or less plug and play jobs with the help of the suppliers and the good folks here and other forums. ?.

Did you ever get the HNC retrofit going? I have one that I am starting soon.

I love my CHNC. Circa 1980. Takes amazing cuts. Very robust and precise. They were not kidding when they put "superprecision" on the machine!

I retrofit with steppers and a 3hp motor with 220 single phase VFD. Not enough low down grunt to do threading (due to the fact that I have to run the motor very low 150rpm to get the Z to be able to make a threading pass.) I really need a good servo on the Z so I can thread at 500-750 rpm. still trying to figure that out.

Regardless, I love the machine. Turret is next...

I love my CHNC and have made great parts for 2 years now. The only problems I've had is with my Hiak Spindle drive.

I Need boards for my Hardinge CHNC GE Hiak Drive if you guys have any.

Year is late 1979-1980's.

There are 6 boards. Looking for some or all.


Thanks much-
