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. ![EEK!](images/smilies/eek.png)
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. ![Smile](images/smilies/smile.png)
