BAQ kaloMAX NT II
After a running-in period of about 0.5 min, the abrasive slurry should be evenly spread
around the ball (see figure).
3.3
Further tests
Remove the ball from the shaft and clean it with ethyl alcohol. Also clean the
specimen. The probe can be moved and further tests can be made. The grinding
craters should have a minimal distance of 1-2mm.
3.4
Aborting a test
A test should be aborted when the ball begins to tumble. Probably a bit of the abrasive
slurry has spread on to the rubber rings or the ball or the specimen has not been
cleaned sufficiently.

Analysis of the wear craters
The wear craters can be measured by means of a surface profiler (depth of the crater)
or a microscope (diameter of the crater).
