Grinding and Polishing Materials
Dry polishing
– OTEC walnut-shell granule HN1/100 (coarse) … HN1/500 (fine)
– OTEC polishing paste P 6
Dry grinding
– OTEC walnut-shell granule H2/100
– OTEC grinding paste SP26
While using dry grinding granulates a higher wear
of the machine is to be expected.
Caution: Keep grinding and polishing materials away from children!
Finishing Problems and Remedies
Problem: After dry polishing, especially with flat work pieces, the surface
looks like “orange skin”.
Cause: The grinding chips during the wet grinding process may have been
too rough (too abrasive).
Remedy: Re-grind in the ECO-mini “wet” with KX 10 (white cones) or try it
with dry polishing after the wet grinding in the ECO-mini “dry”.
Problem: The work piece surface has a lot of little “pimples” after polishing.
Cause: The compound/water mixture during wet grinding was either too
dirty or the casting quality is not good enough.
Remedy: Optimise your wet grinding process before dry finishing.
