Hardinge HC CNC Turret Lathe

I’m looking for some advice on upgrading a Hardinge lathe I recently acquired. I am relatively new to cnc machining, building my first three axis cnc router last year. The lathe is in excellent shape with high quality ball screws. I am upgrading it with an acorn and nema34 closed loop steppers, but need advice on the best way to control the eight station pneumatic turret and spindle rpm. Any suggestions would be helpful. Thanks

Hello. My name is Rafael. I'm new this forum. Just got a Hardinge HNC with cnc10. Clean machine. I use a phase converter in my garage so I would assume that in order to run the control it has to be connected to 3 phase power. I have to turn the Phase converter on. In order to avoid having the phase converter constantly running is there a way that that I can connect the control box to 220v single phase when I program and when I'm ready to cut I can turn on the phase converter?

It depends on the installation. Without seeing a picture of your cabinet, we can only speculate whether it is a factory-wired cabinet or a dealer-installed board level kit.

If it is a factory-wired cabinet, or if it is a board-level kit wired following typical factory practice, then you can run everything except the flood coolant pump by applying 208-240 VAC single-phase power to L2 and L3 of the main switch.

It would be better to post your inquiry in a new and separate thread, since your machine and needs are substantially different from the original poster's machine and needs. Use the "Oak, Allin1DC, MPU11 and Legacy Products" forum for inquiries regarding CPU10-based controls.

Ok Here are pictures of the centroid cabinet and where it hooks up to the Hardinge cabinet where the power comes in from my phase converter

Happy thanksgiving!!! Appreciate your input. I was so concerned but then it came to me that I can run the cabinet on 220v single phase by itself n not have to have the phase converter constantly running.

Its better to run the control on single phase and not use a phase converter.
How is the spindle motor controlled?
Do you have a VFD? What make and model? What HP Spindle motor?
If you don't have a VFD, you could add one and let it control the spindle motor via the Centroid Control.

There’s a vfd already there. My cabinet is 220V single phase. I found that I can disconnect the power cord from where the 3 phase comes in where the power to the cabinet is and plug it directly into my 220v outlet. This has a 5hp motor
