I have a pretty new 3Jaw chuck it used to run true within 0.001" or so. I was doing some work with heavy chatter and next thing I know the chuck has about 0.025" runout on it.
I indicated the OD of the chuck and that's true within 0.004" which from memory was about right to how I set it up when I mounted it to the backplate so I don't think the shift was at the backplate I don't believe there is more then a few 0.001" slop back their either. I checked the jaws to see if there was crap in between where the reversible jaws mount to the base and that was good. I took all 3 jaws out one by one and reloaded them by jaw order but nothing worked. Right now I'm thinking the issue may be something inside the chuck. Anyone ever seen such a problem before? Any thoughts?
It was a nice chuck a few days ago. How does it shift so fast?
