I ordered a new Sieg X3 / G0463 from Grizzly last week. Like most new owners I have a few specific questions... Any help will be greatly appreciated. In return I will be posting a sweet CNC setup in the weeks to come

1. I have a set of Globe servo motors from my old Sherline CNC. They are rated for 60 oz. in. @ 1000 RPM continuous (500 oz. in. stall) when geared down 2.8:1 with a timing belt. Would this give enough torque to drive the X and Y axes (w/ 5mm pitch ballscrews)? Or would I need stronger motors?
2. Assuming I could afford some strong fast motors, what's the fastest feedrate I could get out of the X, Y, and Z axes, respectively?
3. Has anyone added homing switches to their X3 yet, and if so where exactly are they mounted?
4. I had a few questions on selecting a vise in another thread... Hopefully they will be answered there, but if anyone else wanted to chime in on X3 vise selection here, please do.
5. I'll be taking the mill apart completely to make sure everything was assembled properly.. I found an excellent document on how to disassemble it that I will be using. While I'm in there, would it be worth it to swap the spindle bearings with ones of better quality? Or are the stock ones good enough?

Thanks in advance,

Neil
