Deburr Those Sharp Edges!

[rake60]

I have often been accused of being oppressively safety oriented here.
I'll accept that as a compliment!

When you machine metal it is actually a mechanical separation of the
material on a monoculture scale. If you looked at the the raw edge on
the corner of a part that you had just machined under high magnification
and compared it to the edge of the razor you shave with, you will find
the rough machined edge is a finer point.

My brother-in-law was unfortunate enough to follow up on a job where the
previous machinist didn't think it was necessary to waste the time to deburr
a set of freshly turned soft jaws.

Perhaps you've seen the movie "Gone In 60 Seconds"
This was gone in 1/60th of a second.
Just a bump against a spinning chuck with razor sharp edges on the soft jaws.

There is no time to react.
Safety has to be a pre-planned.
A few seconds with a deburring tool or the touch of a file will make a difference.

What could go wrong?
If your head gives you ANY answer to that question address it
before making that cut!

I've been called a Nurse Maid on this issue.
I'd rather be known as as a Nurse Maid than some EMT who has
to pick a severed severed twitching finger up off the floor to
pack it in ice in the hope that it can be reattached, or the poor
old guy in pathology who is responsible for the incineration of
the parts that couldn't.

It IS that real!
This is a great hobby but it has very sharp teeth that don't
know the difference between metal and flesh.

Safety First ALWAYS!

Burrs on parts can be as dangerous as spinning cutting tools and sharp lathe tools that are left sticking out of toolholders. The company that I work for will send you home and give you 2 days off without pay if a fellow worker is hurt because of a part that is not deburred properly. Vacation time cannot be used either, burr related accidents have been reduced to almost nothing in the last 5 years. It only takes a few minutes to make a part safe to handle. Better to be safe than sorry. Peteski

In USAF Machining Tech school handing the instructor a part that was not demurred was a safety violation . If the part was a practical test that meant failure for the test.
safety first, last, and always or safety first injuries last.

You know I carefully de-burr all my parts after a machining operation, but mostly because accuracy on subsequent operations suffers if you don't. I always knew there were also safety issues involved but never realized it could be this serious. I guess now I do it for two reasons.
