DEBURRING (parts under 1/2 " in size)
Ceramic Media is recommended for castings or where a lot of material removal is desired
Ceramic Media is recommended for castings or where a lot of material removal is desired on all materials, but is primarily used on ferrous metals. Coarse media (Briefs) will achieve a dull finish or 24 - 29 RMS in 20 to 30 minutes using Nova vibratory finishing equipment. Medium ceramic media will achieve a better looking surface finish of 18 - 20 RMS in about 1 hour after using coarse media. Fine ceramic media will achieve a luster of 14 to 18 RMS in 1 - 2 hours after using medium composition media.

Plastic Media is the normal choice for non-ferrous and precious metals or most small parts where roughness is not a major factor. Coarse media (Briefs) will achieve a dull finish or 29 - 29 RMS in 30 to 45 minutes. Medium plastic will achieve a better looking surface finish of 18 - 20 RMS in about 1 to 1-1/2 hours after using coarse media. Fine media will achieve a bright finish or 12 -14 RMS in 2 to 4 hours after using medium composition media.

Organic Media abrasive mixes or our blend called 56A will deburr fine or delicate parts. This mix will achieve a sand blasted (without the small dimple texture) or satin appearance in a matter of 3 to 4 hours. Longer time cycles may be required for larger burrs. Also this material is used a lot to achieve an antique look to jewelry. Please see note for use of replacement materials.
