Sharing tool holders between machines.
The stud in cat holders tightened too tight deforming the end of the taper.

Time.
Misalignment.
Crashes.
Ejector needing set.
Knock out pin needing to be reset.
Drawbar tension too low. This will cause the end of the spindle to "bellmouth" over time. Its been a long time since I have looked at a Haas, but most/all of the better machine mfg's have integral drive dogs. With the old "bolt in" style the bellmouth problem is more likely.
It is a haas.

Be specific. Factually state what's wrong with a Haas spindle.

How do you check the drawbar tension on the machines you use?

The people who we buy our machine tools from (Methods) were kind enough to let us use theirs.
I have a Fadal at work and heavy loads on the tool will cause it to have a hard release using any collet so its not a collet issue.
