SawStop is a technology that uses smart sensors to detect the proximity of the fingers to the blade of a saw, and stop in 5 milliseconds.
Just do a quick poll at any carpentry or furniture factory, to discover a worker who is missing a finger, or has suffered major cuts with power saws.
These tools They are dangerous because to use them you have to bring your hands dangerously close to a saw that rotates at 5,000 rpm, and a slight carelessness can cause you to lose your finger …
This does not happen with a technology called SawStop, able to detect the proximity of a finger, differentiate it from wood, and stop the saw in 5 milliseconds, ten times faster than an airbag. You can see how it works in this video:
The theory behind SawStop is very easy to understand, although it is not easy to put it into practice.
The most spectacular thing is that lThe saw blade differentiates the wood or other object from a finger or hand, without using recon cameras or artificial intelligence.
What the saws with SawStop it is send a small constant voltage to the saw hour. When a finger or other part of the body gets dangerously close to it, since the human body is conductive, it absorbs this electricity. This does not happen with wood and other objects, so the blade does not stop with them.
A microprocessor installed in the saw detects the change in voltage and activates a piston mechanism located in a cartridge, which releases an aluminum brake, stopping the saw in just 5 milliseconds.
It is a very effective technology that has saved thousands of professional fingers in the last 5 years.
The only handicap you have is that the aluminum brake is destroyed by the saw (sometimes even the saw blade itself), and must be changed with each use.
Each cartridge costs around 75 euros. It is a high price, but it is worth it if it avoids an accident.
