Small Mill very early design stage

[Robin Hewitt]

If you are worried about thermal effects then you will definitely need the consider dynamics as well, beam/column frequency and moving masses etc.

I see the big problem is that the spindle connects to a slide that connects to a slide that connects to a slide that holds the workpiece. All this with a total slop of < 0.001" so there is something left to allow for flex in the system.

I just don't think it's possible using commercial bearings, there simply isn't enough contact area to take the load.
