I owed a three phase surface grinder 30 years ago. Got it set up and running correctly. Then an employee set a big gen set on the power cable and let the magic smoke out. Rather than fess up he replaced the power cord.
I came into the shop to see the spark stream going away from the deflector and onto a different work staton. Before I could do anything the wheel came off and became a ten pound ping pong ball. nobody got hurt but it was close.

Worst one I had was a 1” wide, 8” diameter wheel that blew apart. I can still visualize the two pieces that flew up and over my shoulders either side of my head.

Turned out there was a steel shaving that had came out of a threaded hole and ended up under a part, I was batch grinding 20-30 parts at a go and missed the shaving.

I was running a "Big" surface grinder (16" wheel) with a DC chuck. Things were going great till the power quit. The work bounced off the wall, how it cleared the spark guard I have no idea. The wheel was in about a million pieces. The chuck was replaced with a permanent magnet one. I didn't think it affected me that much, till the first cut. I about ducked under the machine. It took a while to feel comfortable again.
