Hi my name is Donald. Anthony I hope your are still monitoring this thread? I am looking for a diagram showing the spindle assembly in a Toyoda FA550 12000 rpm. I believe I need to increase the preload, having some finish issues. The ways have been ball bar tested and have a maximum of 0.0001" on all axes at 12.5" diameter. The finish on the parts deteriorates as the day goes on some tools only.

Thanks!
