CASE IN POINT
48 PRODUCTION MACHINING :: DECEMBER 2016
Edited by Chris Felix
Original equipment manufacturers in
the heavy equipment industry continue
to demand stringent cleanliness require-
ments from their suppliers. Where 10 years
ago, particle sizes of 1,000 microns captured
in a millipore patch test might have been
acceptable, today heavy equipment OEMs
commonly demand maximum particle sizes of
600 microns or less. And where in years past, the
gravimetric weight gain of particulate captured
from the millipore test procedure may have had no
defined limit, today that has completely changed.
Now these same OEMs set gravimetric limits not to
exceed 100 milligrams on components that are critical
to the fuel, oil and airflow inside of engines, pumps and
compressors. Tier 1 and 2 machining houses have had to
respond accordingly.
