So, almost 1 year later, still very little information is available on the web.
Besides the other CNC conversion thread on this forum there is only 1 other place where I found some decent info about this mill: https://zuendy.de/2017/06/20/optimum...hrungsbericht/
Anyhow, after Christmas I decided to buy the mill and today it arrived. I still have to clean it and check it with the dial indicator, but so far it looks and feels fantastic. Could not be happier.
It will be converted to CNC in the next months using Delta 750w AC servos (direct drive) and a SZGH CNC controller. I do not really fancy going the Mach4 route.
I measured the lead screws. They are 16mm and there is not much clearance around them, so I can not really say if 20mm ballscrews would fit without milling the saddle (on the X and Z). Y would be no problem.
So far the only difference I noticed compared to the other 25s I saw pictures of is the VFD which now is a Siemens vs. Emerson in older mills. I do not know if this is good or bad since I am not familiar with neither
