Hello Every one I am having some problems with my Imes Icore 240i We have a Imes Icore 240i sometime ago, last week during a milling I heard a weird noise (like a bearing grinding particles) then the machine looks like working apparently normal. However when I checked the copings that it was milling all of them was excesive milled for the same face direction. (long X axis) so I think is time to check the lubrication. I also did a Calibrations routine for all the axis, but still hearing sometimes the same noise. So I will be great If someone have the Instruction manual for lubricate the diferent parts and to do a general cleaning service for this one. thanks allot.
