Is it the Ultimax II control ?

My KMB-3 has Ultimax II and you can run the control on 220-240 volt single phase
The spindle motor and coolant need 3 phase and I used a home made rotary convertor for the spindle, and then switched to a VFD
to allow quieter operations and variable speeds
If you have electronic speed control, you may need 3 phase for the control unit itself, a 12-15 HP rotary would be better.
Phase Perfect is the Cat's Meow --however
