Currently the spindle is not rotating freely.  Elmer is looking into 
having it sent out to be rebuilt and balanced.  This could take soon 
time.  We will give you more info when we have it.

sorry for the inconvenience

Subject: Wafer saw update 8/5/05
Message-ID: <42F3908F.8070401@snf.stanford.edu>

As you know the wafer saw is currently down for a bad spindle. The  plan 
to repair it is to bring field service on site to replace the spindle 
and also to check/repair the whole system so that we can bring it as 
close as possible to factory spec.  Once field service is on site, the 
work will take about 2 - 3 days.  I should have the PO submitted today.  
It will then take a few days for the PO to go through purchasing and 
then we'll have to make travel arrangements.  The best guess right now 
is for the wafer saw to be operational by 8/19.  I will keep you posted.

Regards,
Elmer Enriquez

For those of you interested...

The service fellow is here!  Unfortunately, the spindle assembly is not, 
due to a FedEx misdelivery (or rather, missed delivery -- they 
apparently forgot a pallet), but is due to arrive tomorrow morning.  The 
service guy (darn, I forgot his name) also just found that the rotation 
gears were trashed, but luckily thinks he's got a lead on replacement 
parts.  In summary, it's not likely we're coming up this week, although 
hopeful for Monday (really hopeful, as our fellow has plane tickets for 
Monday morning.)  More news later --

Hello wafersaw users --

Things were somewhat delayed due to parts, but our field service guy is 
on top of it.  The rebuilt spindle looks great, the rotation assembly is 
being rebuild now (which will hopefully address the intermittent 90 
rotation alignment problem), and he replaced a charred wire on the 
Z-axis tach (which will hopefully address the intermittent 
Z-overshoot.)  The way things look, the system will be back up to 
greenlight status certainly by lunchtime tomorrow.  It may be back up 
earlier (and if there are any expert wafersaw users willing to volunteer 
to check the system out in case it is, let us know.)

Mary
