I have a fairly new TMX Set-tru on a TL2, that since it was very new (one other machinist used it for 2 months before me) has failed to repeat at all. I can dial in a precision ground pin, then loosen and re-tighten the jaws (moving nothing) and have it run-out up to .010". So, for the last five years I've had to indicate in virtually every part not turned out of oversized stock. Is this normal? My boss is considering replacing the chuck, but if any replacement would be just as bad why waste the money.
Previously I spent 95% of my time on mills, and what little lathe work I did was using 4-jaw or collets. Thus my lack of experience with these dubious 3-jaw chucks.
