7. Use and Function of the Machine
The disc finishing machine
Eco-mini „wet“
is used for the wet
surface treatment of jewelry and work-pieces in the dental
Laboratory (mainly wet grinding).
Here the objective is to replace hand preparation (emery paper-
work) of a work-piece by wet grinding with the
Eco-mini „wet“
and to create a surface which can be polished afterwards with a
dry polishing machine like the
Eco-mini „dry“
.
·
The top of the process container is open and the disc
at the bottom is designed to rotate. The container wall
itself does not rotate.
·
When the process container is filled with polishing or
grinding media and the disc rotates, a toroidal move-
ment is generated, which creates a long frictional path
resulting in an extremely efficient polishing action on
the work piece.
While wet-grinding, the water/compound mixture is continuously
added to the media through a pump. This helps to drain the
residual particles of the grinding process out of the work-
container and to grind the work-pieces smoothly, keeping them
clean and free from corrosion.
The waste-water flows via a hose into the waste-water con-
tainer where the larger waste particles can settle and the wa-
ter/compound mixture can be pumped back to the process.
After approximately 10 to 16 working hours the wa-
ter/compound mixture should be replaced, otherwise too much
