For work-pieces with weak spots or a high risk of breaking or
being damaged, the manufacturer Otec Präzisionsfinish, can
not give any guarantee.
Well set, precious stones, usually do not work loose or fall out
of the jewelry. Set stones, which get loose or fall out of jewelry,
can not be guaranteed by the manufacturer, Otec Präzisions-
finish.
Generally, precious stones up to a hardness of 8.5 (Mohs) can
be processed without damage in the
Eco-mini „wet“
.
8. Problems while processing and remedy
Problem: A very thick foam which does not disappear is in
the waste-water container.
Cause: There is too little compound in the water or rather
the compound is used up.
Remedy: Increase the concentration of the compound.
Problem: After polishing you can see little “pimples” on the
surface of the work-piece.
Cause: The water/compound mixture is too dirty or the
casting quality of the work-piece is poor. (Is there silicon in
the surface of the casting?)
Remedy: Exchange (refresh) the water/compound mixture
and/or improve the quality of the casting.
