Chiron UK seemingly contacted Chiron Germany and they said there were no spares available for my machine with the exception of release fingers, or something like that. What they are I am not sure.
If you get a chance to look at the drawings could you see if it has the bearing numbers for the ends of the ballscrews please. My X axis has a bit of backlash (0.02mm) and I am thinking it will be the bearings, the Y has under 0.01mm backlash and Z doesnt seem to have much at all.
Does your toolchanger have the lower cover? mine just has the steel upper part and I dont really know what the lower part looks like.
