Those motors are massive and you will get away with far smaller motors.
Seen has most lathe conversions I've seen are geared 2:1 then 3Nm Nema 23 and 75V PM752 or 50V Pm542's will easily do what you need far better than those big motors. Even 1:1 they will be fine.!

Don't fall into the bigger is better trap.!! . . . 3Nm 23's when connected to ballscrews are are very powerful and run with decent drives and decent amount of voltage will be fine for your needs.

I can put you in touch with someone who is selling some New PM752 drives if your ready to buy now.? . . . . PM quick if your interested.
