NANO 1000T / FEMTO 1500
Polishing Head
5.9 Positioning and Loading FEMTO holder
1. For grinding with abrasive papers, the specimen holder
for the FEMTO head should be positioned so that the
specimen tracks over the entire radius of the grinding
paper.
Since grinding papers break down relatively fast, it is
recommended that the hardest part of the mount
(typically the specimen) track over the entire radius in
order to uniformly break down the grinding papers. If
the specimen does not break down the grinding papers
uniformly then the softer outside part of the mount will
grind more. The result is after polishing there will be a
portion of the mount which is not fully polished. This
portion of the mount will appear as a crescent shaped
moon and can cause issues when examining the edge
of the specimen.
TIP: If you have small samples, mount them toward
the outside edge of the mount for better tracking
2. Individual specimen holders do not hold the specimen
in the holder. When the head is lifted, the specimens
will remain on the working wheel. In such a case they
will need to be reloaded after changing the abrasive.
TIP: By placing a rubber O-ring around the top of the
mount it can be lifted when the head is raised and held
in place. Note you most likely will not be able to do this
if you use the splash guards.
You can use O-rings to hold
specimens in place when
head is lifted
Position holder so that the
specimen in the mount tracks over
then entire radius of the grinding
paper.
