There are many different abrasive materials available and I’ve read
the catalogue descriptions. I still don’t understand what the real
differences between them are, as they all sound like they do the same
things. I would appreciate feedback on which abrasive experienced
jewelers use for what purpose. I am particularly interested in
cleaning out the inside of rings that have been sized up. Cost
effectiveness is also an issue as I size up about 40 rings each day.
I’ve used the aluminum oxide cartridges, but they “blow apart”,
rather than wear down, once or twice a week. The guys in the shop
all use these. They don’t use the sanding bands, saying they have
the same “flying apart” problem.
The trizact bands barely lasted through 1 ring before becoming
uselessly dull. I tried these with and without Stuller’s lube.
The 3m Imperial micro-finishing film is great for use on a sanding
stick, but wears out too quickly in the small bands.
I love the 3m flex diamond bands, but they’re really expensive. The
other band abrasives I’m aware of include: Silicone carbide, 3m
Cubitron ceramic (Purple), 3m Trizac CF (Green), and 3m Diamond
microfinishing bands. I thank you in advance for your feedback on
what abrasives you use, and those you don’t care for.
