7.2. Grinding with the Eco-mini „wet“
7.2.1. Grinding Media
In general one distinguishes between two different kinds of
grinding media:
·
Ceramic-bond media (especially for the dental sector). Here
the ceramic abrasive media is bonded in a ceramic substance.
Advantage: short processing times, high pressure to the work-
piece. Also many different shapes can be produced.
Disadvantage: ceramic can damage soft surfaces such as gold
and silver.
·
Plastic bond media (especially for the jewelry sector) Here
the abrasive media is bond in a plastic substance.
Advantage: fine, smooth surfaces can be achieved.
Disadvantage: more expensive than ceramic media.
In these operating instructions we want to concentrate on the
use of plastic grinding media.
7.2.2. Plastic Grinding Media and their Application
There are generally two forms of plastic grinding media:
Cones with the prefix “K”. They are especially suitable for even
surfaces, jewelry with cubic zirconia, Sapphire etc. Through
their round shape they will achieve a finer surface finish than
with a pyramid shaped media.
