I’m talking about the blades that are cold cut metal blades, so they can cut without sparks etc, and leave a clean cold edge. What’s the science behind them? How do they work so effectively?
In: Engineering
Hard things cut soft things. Instead of cutting by heating the metal molten, it cuts out chunks with the blades the same way skilsaw cuts wood without burning it.
The science is attaching really hard teeth like carbide (that like to shatter and don’t weld easy) to a flexible and strong blade with the right number of teeth and shape and speed to stay stable during cutting.
