So the moment of truth....
T.I.R on the inside of the collet chuck is .0005",
T.I.R on the body is .001"
I chucked up a 10mm reamer and I'm getting almost .015" run out...
Advice, where do I start looking to correct this? I don't have any pin gauges, or drill rod that I know for sure is "perfectly" straight.
I have not removed the piece from the lathe since I started turning it. I felt this was the best option to alleviate repeat-ability issues. I will do this once I have a bench mark to compare it too. I have a witness mark on the spindle and the holder so I can remove and reinstall in the same orientation going forward.
I feel I need to test other sizes, to see if there is some kind of pattern. What is the most effective way of doing this? Since I have not yet acquired an imperial set of collets to use a simple set of drill bits (theoretically these should be reasonably true).
I tried rotating the collet in the body and rotating the reamer in the collet and didn't get any significant changes, better or worse.
Yes, these are chinesium and I have heard read some posts on the quality issue, is it simply poor collets?
