I bought an old CHNC with no control on it two weeks ago. Spent about a week worth of work on it ( thanks to company furlough). I replaced the servos with steppers and also replaced the spindle motor with a Hanning 220V 2kW motor. I also replaced the old spindle feedback with a spindle index pulse assembly the way MACH3 likes it. I did my initial testing with with a G540 since its so darn simple and was running both axes at 120 IPM with a 48V supply.
I then started the task of getting the collet closer running (vari-grip type). I haven't working with something like this before and was wondering if anybody had a manual or instructions on the collet installation and removal process on a CHCNC hardinge lathe?
Thanks,
Daniel
