[TheForge] chinese ASOs

Yes you could nickel braze it in a vacuum furnace if you have the $$$.  We
used to make some parts called Theta Axis Units.  What there were was a
precision bearing housing, and a spindle plate that you drove with a servo
motor for grinding the edges of silicon wafers. See the bottom of the page
http://www.automationtechnology.com/partsmanf.htm.

For a long time the face plates were required to be manufactured from
stainless and the shafts from carbon steel for tolerance reasons.  The two
pieces were press fit, then vacuum brazed together, to form a spindle unit
that a vacuum chuck could be mounted to.  This came at a very high price.
But on a 9000.00 dollar high accuracy grinding platform nobody cared.  When
I left the company we had started to make them from a single piece of stress
relieved stainless.

Enough Rambling.  You can vacuum braze about anything, it just cost allot of
money.
