Both dry grinding and dry polishing can be done in the ECO-mini.
Walnut-shell granule of various grain sizes, impregnated with polishing paste
or grinding paste, is generally used for processing.
The coarser the granulate, the better its smoothing property.
The finer the granulate, the better the shine.
Dry grinding
Work pieces with a strongly scratched surface or that has been pre-processed
too roughly can be processed instead of wet grinding.
Dry polishing
Customer jewlery that has lost its shine or tarnished store window exhibits
can be dry polished.
