What is the acceptable runout on the face of a wheel adapter? I am sorting out my Boyer-Schultz Challenger (6-12). I have 8 or 9 adapters all are left hand except for one. That one was on a wheel that probably was not used on this machine. I wont use that for obvious reasons. I cleaned up all the adapters and with my Mitutoyo tenths indicator, all I see on all but 2 of them is a bit of "noise" when I check the face of the adapter. (less than a half a tenth) One has a thou runout on the face and the other has a thou and a half runout. Looking at them very carefully, I cannot see any dings or scratches on the taper. I spun them in a lathe and cleaned them up with some flitz polish but the runout remained the same. I am sure that the runout is in the adapter and not the spindle. I have a Brown & Sharp 50 millionths indicator that shows just an ever so slight needle wiggle when I rotate the spindle by hand. I have a vfd on the machine so I slowed it down to a couple hundred rpms and the ruby tipped indicator showed no movement at all. So back to the original question. What is the acceptable runout on the face of the wheel adapter?
Thanks,
