best with heavier cuts and greater material
removal. Fine cuts combined with tool loading
can contributed to smeared surfaces.
The Flex-Hone Tool from Brush Research
Manufacturing (Los Angeles, Calif.) provides a
better way to improve the surface finish of
anodized and hard-coated cylinders.
With its unique construction, the Flex-Hone
is comprised of abrasive globules that are
permanently laminated onto the ends of

flexible nylon filaments. Because the diameter
of the tool is greater than diameter of the
bore, the Flex-Hone is used in an oversized
condition and is self-centering, self-aligning,
and self-compensating for wear.
Importantly, the Flex-Hone tool’s abrasive
globules “float” to ensure that all parts of the
bore – and not just the high spots – are
surface finished. Unlike rigid honing
machines, Flex-Hone setups are simple, too.
Surface finishes can be improved with just a
few strokes of the tool and the results are
consistent.
The Flex-Hone Tools can be used prior to
anodizing to control the size in anticipation of
the shrinkage in ID. Honing also removes
“fuzz”, sharp edges and any amorphous
material that might adhere to the surface and
affect the quality of the anodizing.
The most common usage for the honing
tool, however, is after anodizing to correct
unanticipated size and surface finish issues.
When the quality of the final anodized finish is
of the utmost importance, some even use the
tool before and after.
With anodized coatings, the recommended
abrasive types are aluminum oxide (400, 600,
or 800 grits) and levigated alumina (extra fine
only). Choice of grit depends on the type and
thickness of the anodized coating and the final
surface-finish specification. Flexible honing
tools are available in sizes ranging from 4mm
to 36 inches.
