Beryllium Facility #2 – Plant Diagram

Photo #1 – shows a view of the machine shop, lathes and a lathe
operator.   The lathe operator manually inserts 10-12 foot metal rods
(containing 1% to 2% beryllium) into the long tubes seen in the
photograph.  In this photo the cutting shield which is used to control
cutting fluid splashes is in the up position with the operator preparing
for a run.  During operation the shield is down and the lathe
automatically feeds metal rods to the cutting end of the lathe.

Photo #2 – metal rods are automatically fed to the cutting end of the
lathe where the final product and cutting fluid flow into a trough where
the pins are collected.  The machinist stands at the cutting end, but
moves around throughout the machine shop to monitor the operation of the
lathes and collect random samples for inspection to ensure proper
operation of the lathes.  Cutting fluid is used to aid the cutting
process, to extend the life of the cutting tools and to control and
contain the release of dusts. 



Photo #3 - An Air King M-35P downdraft booth was the lone operation
equipped with local exhaust ventilation.  The booth is approximately 6
feet high by 3 feet wide and 2 feet deep, and is equipped with a HEPA
filter and is exhausted to the outdoors.  The operator stands at the
face of the booth to grind and buff small diameter rods.  The booth is
used on an intermittent as needed basis to chamfer smaller diameter rods
on a bench grinder/buffer contained within the booth.
