Very, very nice build! I'm in luck that I have the machinery that I have available - might be able to save quite a lot of bucks that way.
I was looking through HIWINs products yesterday, and I came across some linear guides that I haven't considered before.
The plan is to mount the X-axis onto the back wall of the machine with two QRW45CC linear guides, and one 32mm double-nut ballscrew. Then mount the Z-axis onto the slider plate of the X-axis, with the Y-axis mounted to the Z-axis (if that made any sense). I could throw up a quick sketch in paint or something when I get back home tonight, as I don't have my CAD-computer at the moment.
According to HIWIN, the QR series offers super-high rigidity, and quiet operation - combined with long running life. Sounds like exactly what I need - or do you think this is a bit overkill?
Hanermo says that I would be just fine with 400w servos, what is your thought on this? I'm starting to realize that I have to compromise with the some of the electrical components to be able to run this mill on 220V single phase. I found some 750W servos for quite a bit cheaper than the ones I posted in the OP.
