I noticed a significant improvement in surface finish when I converted my Myford Super 7 to 3 phase, I would never go back to single phase for a lathe or mill,

The motor is bolted to the the headstock but the drive is via belts and it's spinning a big old chuck so may not be too bad.

I'll face off some ali and see if there is any sign of uneven cut.


So when you fitted a VFD, I assume you delta the motor and wire the VFD direct to it? I read that VFD's like to be close to the motor and don't like contactors etc in the way.

Did you re-wire the fwd rev microswitches to operate the VFD or just add a control pendant/box for the VFD?

I would like to retain the fd rev lever and footbrake.
