massive congratulations to Kern Microtechnik, Germany: using a custom
made 10 micron endmill fitted in a Pyramid Nano 5 axis mill, they've
managed to engrave a hair! The hair is around 80 microns thick. A true
miracle of mechanical engineering.
The only other Pyramid Nano in the Southern hemisphere is located in Brookvale...
By the way, if you are wondering who made
the 10 micron end mill: it's Zecha. In 1964 Erwin Zecha started his own
tool making business, in his house. The entire workshop consisted of one
12 square meters bedroom. And he trained his first toolmaking
apprentice 24 years later, in 1985! Talking about taking it easy...
Anyhow, today Zecha is one of the leading German precision tool
manufacturers still holding onto his original motto: "Start small, grow steadily and never lose sight of the horizon".
