"DarkMatter"
I manufacture Piezo motors and control systems that operate in the
100 to 1000 micron range. The amplifier that excites them are 1.5kW,
800V
EXTREMELY low distortion amplifiers. The piezo stacks are hundreds of
wafers each, and an LVDT is used to determine position in real time,
as the lathe head it gets used on can cut optical quality surfaces on
the first pass. It can also cut a square peg from a round pin on a
spinning lathe. Use your dim wit to figure that one out.

Your little tenth of a mil baby bull**** is child's play by
comparison. Laser etched optical rules, and magnetic types are
nowhere near the resolve of these machines. They even detect and
remove backlash artifacts from the lathe head, and lathe machinery.

Gotcha! Not that *that* was any chore.

Learn how to refrain from top posting, retard boy. It is as simple
as that.

I think we have a winner.

Now THAT was an interesting post.
