Re: DMM motor sizing query
I have DMM servos on my lathe and have been happy with them. If I had it to do over I would use Delta servos, easier to set up and price competitive with DMM. I have a Delta servo for my spindle motor.
''I will fit a centroid controller and probably an oak so to have feedback from all axis.''
Good call
''Is this feedback needed for a lathe Z and X.''
Yes if you want good accuracy.
''Do the Dyna4 controllers communicate with the centroid oak controller.''
Yes. I use Analog Torque Mode
''Is there any suppliers of these products in Australia.''
I don't know. I think DMM only ships from Canada.
As far as sizing, compare the specs on the Fanuc motor to the Delta or DMM specs and choose motors that meet or exceed the specs. Especially torque, also consider the frame size.
