Re: DM4400-what size 3 phase motor for rotary converter
Just as a note of caution, when you're swapping parts to make one good machine out of two, the three ball screws are fitted to each machine uniquely.
If you take the Y ball screw out of one machine and tried to fit into the other, the bolt holes will sort of line up but not 100%
And when you start the machine back up, it makes horrible noises.
Trust me on that one.
However the balls screw assemblies are pretty easy to service.
So is the spindle motor. I've rebuilt two of mine already.
Super smooth and quiet with new bearings.
