Chuckle!

I'd question just how "high end" the shop was when they pull tricks like
that. My opinion? They should have replaced the guy that screwed up,
not
removed the indexing pins from all the machines.

Have you ever used a machine with a power drawbar? On the ones most of
their mills were fitted with when you tripped the handle it took about 0.5
seconds to fully tighten the drawbar. I presume some one was changing the
collet and just tripped the handle a bit sooner than they meant to.

No, I have not, but under that circumstance I can see how it could happen to
anyone. There was no mention of a power draw bar originally. If that be
the case, I stand corrected. Still, with just a *little* care, it could be
avoided!

My mistake, I should have mentioned that all of their mills had power
drawbars. I agree that in the absence of same that anyone abusing a
machine by pulling a collet past the index pin should be fired on the spot
for total incompetence.

I'm from the old school where everything that was done on a machine was
done by the operator. Skill level is what sorted out those that could
from those that could not. I can see that CNC has changed all that.

I don't think that CNC can really be blamed on the decline in skill
levels. The blame lies partly with the education system. How many schools
do you know of that still offer any training in "hand arts"?
