Might be a little hard to see
But there is a sort of a “dot” in the image below. This is the face of a car part immediately after machining.
The “dot” is a clever bit of differential tempering. Outside the dot, the only tool that will touch the surface is Cemented Boron Nitride, or CBN. Basically, the closest thing in hardness to diamond. Inside the dot, you can cut it with a pocketknife. The reason is, after heat treat, holes have to be very accurately drilled and reamed in these spots. Can’t be done prior to heat treat, because the holes would distort. This is the capability of modern manufacturing, and it borders on witchcraft.

Cool stuff. The future is not here yet but it is a lot closer.
Agreed, very cool. Thanks!
Hello, I am from your future. Everything is fine, in case you are wondering. Things are getting cooler everyday. You think what you have is cool, you haven’t seen nothing yet.
BTW: Keep On Truckin’ has become our national motto. How cool is that!
As Spock would say: fascinating.
Yes, fascinating. What part in particular requires this and what level of precision? Just curious.
Thanks.
I can’t say, and 10 micron true position.
That is just freakin’ awesome.
I don’t know what to think when the guru says it’s not quite black magic. Except, “Wow.”
Was it Heinlein that wrote “Any sufficiently advanced technology is indistinguishable from magic”?
That’s magic.
Clarke. And yeah, damned near.
