Hello everyone, Im a longtime lurker just registered on this forum. I was able to save a nice Maho from the scrapyard a few weeks ago. I got it for free, and I am now in the process of bringing it back from the abyss of death... there will be a lot of questions Im sure, but first off;
I disassembled the z axis ballscrew for cleaning off the caked on old lubricating oil/dirt, and upon assembly I find it odd that the six separate ball recirculating circuits are not filled with balls completely...to make each circuit full there are 4 or 5 balls missing. For all I can tell, the ballnut has never been disassembled before, so my question is if this is normal for this kind of internal recirculating ballnut? The machine is from 1986, and the ballscrew assembly is the original part.
Cheers/Lasse Svedberg
