Nova Finishing Systems Inc., has pre-selected and recommends the following media for use on most small parts under a 1/2 inch in size. Depending upon the roughness of the parts you are working normally the fastest way to achieve a good looking surface finish is best accomplished using a series of processing steps than by selecting only one media. To accomplish these tasks, the following is a description of our processing recommendations:

DEBURRING

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.

BURNISHING

Burnishing is normally accomplished using steel or porcelain ball media. Our recommendation is to use porcelain ball media called microbrite over steel even though it does not work as fast, because you don't have maintenance problems, work harden, bending, or distortion of thin parts. This media is recommended as a secondary step process after ceramic or plastic deburring. Mirror finish appearances are possible in 2 to 4 hours. The longer the time cycle the better the appearance.

POLISHING

Organic media achieves the finest surface finishes of all media; however, it also takes the longest amount of time. Our recommendation is to use our 56D or 56E blended mixes which uses porcelain ball media to help -speed up the finishing process significantly. These products are exceptionally good at achieving an almost buffed appearance on small and detailed parts. The product 56D is a softer material used primarily on aluminum, brass, or pewter, whereas, 56E is used on precious metals. Please see note for use of replacement materials.

STARTER KITS

Kits 5 and 6 are excellent beginner processing supplies and basic to achieving a good surface in the shortest period of time.

SHORT FORM RECOMMENDATIONS

Media selection is based upon general applications and preform versatility. "Briefs" indicate only coarse media and "Kits" consist of equal packaging of fine, medium, coarse media. Model numbers show recommended capacity of media requirements and Nova equipment.
