An unbelievable technology "Table-saw stops itself when touches finger"

There is about 60,000 medical treated accidents on table-saw every year that 3000 people take the finger off by 10 a day.

Steve Gass the pioneer of a table-saw which stops itself in some micro seconds when it comes in contact with the finger. And he named it as Saw-stop. He wanted to bring that accidents figure to zero. So he designed a system which can tell the difference between wood and finger.

When you are cutting wood and if you accidentally run your hand onto the blade it will stop so quickly and you can take your fingers off the blade. The blade is a acceptor it detects the electrical conductivity. A piece of wood is not very conductive so the saw goes right through it and a saw to your wet finger is conductive. It is like a touch device, there is an electrical signal on it which conducts that signal in human body, human body absorbs that signal that triggers the system and portion of machinery at the back of the blade helps the blade to stop in a fraction of second.

The blade rotates at 5000rpm and this system stops it in 1/1000 of a second and saves the finger which is something very hard to believe. By doing this action machine does not feel happy, it is something like you are driving a car 1000miles/hr and it hits the wall. By doing this action the machine is officially trashed and it costs you a $50 but in replacement of saving your finger.

This is the unbelievable table-saw machine called saw-stop:
