Automatic Pencil Making Machine

Each individual slat goes through a machine called the Groover Machine (not to be confused with someone who can't stop dancing) that cuts — you guessed it — grooves into the surface of the wood. This preps the wood for graphite.A pencil is primarily made out of wood and graphite. The graphite is ground down and mixed with powdered clay and water to make a thick paste. This paste is then fired in a kiln. The result is a strong lead core that's difficult to break and extremely smooth for writing on paper.The pencil may seem a simple device in contrast to the computer, but although it has fewer parts, it too is an advanced technology.
