Testing the performance of the G540 and NEMA 23 motors on a RF45 mill
Chris,
Overcoming the heavy moving weight coupled with rapid inertia is a concern.
The NEMA 34 motors and G203 drives would produce double or even triple the torque and holding power.
On the other hand it would be interesting to see the performance of the G540 and NEMA 23 motors on a RF45 style mill, it may work just fine.
If it works well you would not only save yourself some cash, a lot of Zone members would benefit with the knowledge.
Worst case scenario you could always sell the Nema 23 motors and G540.
There is a big demand for them here on the Zone.
Please keep us posted.

Clocker... so what are ya gonna do....
About your ballscrews and mounts? I suppose with a direct drive mount you could make a simple plate with standoffs that houses the angular contact bearings and then do like I did and bore the floating end factory mount for a simple bearing. The X is the hardest part since it has to be free from binding down the length of the tables travel. The Z axis is floating on one end as is the Y axis so they are not so critical. When you get going on it be sure to post some pictures of the machine and your build as well as the obligatory video of it running at the end!!! peace....
