Took delivery last week of HARDINGE HC CHUCKER serial # HC4172-P
with wiring diagram # CHE 8220. Machine is 1.5hp, 60 hertz, 3phase,
220, w/ 3phase 1740 GE spindle drive motor. Machine is supposed to
be 1984 vintage but I cant say for sure.
A. Does anyone have the wiring diagram ? CHE 8220
The machine came with the parts list and a sales brochure
that dates from the 1980s.
B. Are any other manuals available ?
This is new ground for us. Appreciate any help.
C. We just plugged it in. It was turning in the
proper direction...we all think....but the carriage ran slowly then
the machine stopped cold. Would like to have wiring diagram
so we can find our way. The wiring diagram for the HLV doesnt
get it done, unfortunately.
Thanks to all.

Unless the motor is on a VFD my first test would be to check voltages at wiring to motor ... do they look reasonable... all three phases to neutral and phase to phase. If you have a phase meter even better...
If voltages look OK, remove the motor and benchtest it... if it runs OK problem is likely to be mechanical rather than electrical.

There's some HC documentation in the files topic of the yahoo hardinge group
I didn't see the circuit specifically, but there is a maintenance manual so it may be in that.
