We run a couple of Cincinnati Centerless grinders with those big ole stone wheels in them.
!KABOOM-CLATTER-BANGITTY-BANG!the other day. The wheel just self destructed without cause. The guy running the machine is one of our good guys, wasn't a Machinist error, he didn't drop a part into the machine wrong, nothing jammed between the wheel and part rest.
I got a look at the situation after the housing cover was removed, and the entire Centerless wheel was nothing but a pile of busted up pink "gravel" under the spindle.
Foreman went over and investigated, best answer at this point is the stone wheel had one or more fractures in it that finally let go.
No one hurt, we are pretty good here overall with insisting people wear safety glasses, the wheel disintegrating under power was pretty much contained within the housing.
But, an eye opener and reminder: Wear your eye protection if at all possible, and if the unexpected can happen it will find a way to happen, either sooner or later.
