From the beginning of endless time,
They have been with us.
Mocking us,
Betraying us,
Cutting us,
Taking our loved ones away.
Burrs are the material that is left on the edge of material after it has been cut. They grow worse as the tools wear. They are sharp and will cut you faster then a "your mother" joke in gangland.
Aluminum burrs are annoying, but easily removed, once you know how. Sandpaper and a scalpel will work 90% of the time. They might cut you on occasion if you disrespect the gremlins in the machine.
Steel burrs need stronger sandpaper and special blades, sometimes even a grinding wheel and steady hands. Sparks fly when a tool breaks, and we normally run steel in "Oil" machines (oil=flammable ). Steel burrs WILL cut you at least once per week.
Burrs on small (or thin) parts. There is no good way to deburr them on sandpaper and leave your finger nails and fingers intact. Latex gloves are too thin and will be worn through after 3-4 parts (even the thickest ones will only last 6 parts at best), and heavier gloves cause you to loose dexterity and grip...... You will sand your fingers until you BLEED. (usually takes 2 or 3 shifts for them to start)
Plastic burrs (and parts) are the worst though. They wont cut you, but they dont want to be removed either. Normal deburring methods will damage the parts so you have to be extra careful. Plastic also compresses, So you need to know the Exact amount of pressure to apply when measuring the parts, and where to apply it. Plastic is like that one 'friend' who annoys you, but wont leave. They might not cut your flesh but they WILL cut your Soul.
The there are the CHIPS oh chips, I loath ye. Chips is the material that is cut away from the part. normally 60-80% of the raw stock is cut away, but it can be up to 98%. Usually they are small and solid, and are easy to clean up. Others are loose and form a thread.
These "Thread Chips" are the root of all evil (the 'snake' in the Garden of Eden, it was really a tightly bound coil of thread chips ). They will get caught in anything that moves, like a conveyor, tooling, the spindle (on the lathe side). When the get caught they need to be removed. Removing them is like sticking your hand into a barrel of razor blades, you will be cut faster than sticking your hand into a barrel of razor blades!! I even have special gloves to pull them out, I stillget cut. I pull them out with pliers, (gently brush up against the threads) and I STILL get cut. If you look at them the wrong way, you Will still be cut!!! I looked down at my hand on time, I was bleeding, but did not remember being cut. They are so sharp, you will not feel getting cut until you notice the blood.
And this is why I get my Tetanus shots updated every 3 years now (normal people should get it every 10, but most do not). I dare you to read that Wiki article. You will be making a Doctors appointment within an hour (if you dont, you are crazier then I am. ).
