Turning a simple part in a CNC lathe, face, turn, thread, groove and cut off, 30 part run, the back side will be done in a second op. On the 21st part, at cutoff the part flips into the counter bore in a chuck jaw at just the wrong time, and smacks the turret hard enough to stop the chuck and knock the turret out of alignment. Never seen that happen in 30 years of CNC lathe operation. Does anyone go to the trouble of putting caps into the counter bores of the jaws of their 3 jaw to avoid something like this? Or is there some other trick? Or is this just a once in a lifetime piece of bad luck?
