This happened to me on Thursday night (two days ago) about midnight. Let this be a warning to others.
This was the setup - 3/4” end mill running at 1500 RPM. I had just squared off the end of the small stainless steel part, ready to do the same operation to the next part in the 8-part run. With the spindle still turning, I loosened the vise, reached around behind the cutter to remove the part (very stupid), and in a flash, my finger was grabbed by the clockwise-rotating end mill which pulled the finger through the 4mm slot between the side of the vise and the rotating end mill.
The result is shown below, taken in the ER about an hour later. If you're squimsh, DO NOT click on the photo. I lost a lot of blood and was pretty weak, thankfully my daughter was home and got me to the hospital pronto, not sure how I could have even called 911 alone. The end of my index finger was basically put through a meat grinder, and the last digit bone was crushed into pieces. The fingernail and tissue below it were badly severed and ultimately removed completely in the ER. Joints and tenons appear to be functioning, and nerve damage appears confined to the inner right side of that finger. Not clear what the longer term prognosis is, but I'm expecting the last digit on that finger will have to be amputated.
This was a stupid accident. I was tired, wanted to finish the job and got in a hurry. Lesson learned: turn off the machine before putting your hands anywhere close, and if tired or in a hurry, stop and come back tomorrow.
