E-STOP!!!

[Perfect Circle]

Hey guys I thought it would be something to talk about.
Maybe..Maybe Not.
Short Story: I just threw a 17' dia. split bearing out of the chuck, Im not "Perfect" The 2 halves where held together with a hose clamp, and out of all the times it could break it would while I was taking a roughing cut.
Its just a crazy phenomenon that as soon as you see something going wrong and how long it takes to hit the E-STOP is amazing to me.
Maybe yall can come here to tell of your war stories of your great crash that seems to make time stand still.
Thanks

Like I have said a few time here before, the big Red button on the panel is always the hardest button to find
Maybe a good time to revisit this one!

Do you really want horror stories? I've seen my share. I was usually "invited" to investigate a lot of "mishaps".

Sure!
Very good Story about being safe Al....
Thats what I hope people can read here on this thread because ive seen too many people get hurt in this line of work not understanding that a machine will get you faster than you can say dont do it!
Everytime I read a story like that it makes me more safe than I was before I read it..because you can see it happening to you.
Thanks for sharing.

OK then. I'll start with a middle of the road one then. I have some worse, some kinda funny in a demented sort of way, and some tragic.

Get a call from a customer. Machine just made hamburger out of someones hand. ( the machine was always known as the handburger after). This was a fairly large machine builder, not a fly by night company. A guy was putting a 6" shell mill in the spindle by hand. One of those super sharp aluminum finishing ones to. According to him, as soon as he hit tool clamp, the spindle started at 6K RPM. Could never verify, but the tool clamp and cycle start were both green buttons on the pendant. Either way, I go to make an initial visit within 1 hour of this. I find pieces of palm, fingers, and what appeared to be tendons still blown around the inside of the machine. The guy ended up leaving the country from what I was told later.

I've got some great non-machining types of accidents.

Years ago when in high school, I worked stocking a bar in the early mornings. Heard yelling from the kitchen one morning, rush in...the prep cook had pinned back the blade guard on the meat slicer to cut 1.5" thick slices of prime rib.

Took his thumb clean off at the joint, exactly parallel to his index finger. Put the finger in a cup of ice and sent him up the street to the local naval hospital, where they put it back on (successfully). Next day, the manager fires the guy. That's having a bad week alright.

Needless to say I was a big believer in a push stick on the high school shop table saw after that.

When i was in high school, we had an offsite school we could go to to learn specific trades. I was dumb enough to learn machining One day, in the grinding room, one of the students decided to wipe off the table on the Brown and Sharpe surface grinder. Well, he forgot one critical step in that process. MOVE THE WHEEL UP. Yep, a 1/2 slot through his four fingers, 3 halfway through the bone.

For more of my stories, we will need a barf smiley.

I used to setup and operate a nichols double face mill. we used it to mill across the flats on the heads of bolts. If you have ever seen one it is just two face mills across from eachother with a sliding table. no gaurds. we use to drape plastic over the top to keep coolant from going everywhere. well i set it all up and was running but the coolant was hitting one of the cutters and spraying me when i would lift the plastic to chuck and unchuck the part. so i grabbed the coolant hose and started to adjust it (me being a 19 year old rookie running a machine from the 40's) i didnt turn the cutters off. as you can imagine the coolant line popped off and my hand went straight into the cutters. luckily i was able to whip myself backwards onto the ground instead of totally into the cutters. without looking i pulled on each finger to make sure they were still attached since it sounded like a bolt going through the machine when my hand hit it. all fingers still attached and 40 stiches later i was ok. close call. lets just say i always remember to stop machines before making adjustments!
