Until the present day, the most efficient and nonabrasive method to harden surfaces has been ball burnishing.
Items are hardened and polished in a mass of steel balls, often in a vibrating bowl, rotating sextagon or octagonal drum, submerged in a lubricant of soapy water. The action of these containers is non-abrasive and the hammering hardens the surfaces from all sides. Plating, for example, is prevented from lifting, being firmly hammered onto its base metal. Polished items have a much longer life expectancy, as the compacted surface is more resistant to wear, scratching and corrosion.
Due to the unique action of this machine, the “orange-peel” effect caused by typical burnishing equipment is not an issue. Extensive testing on silver, gold and platinum jewelry has proven the Brunimat to be the most effective machine that yields the best results.
The FM-Bruni-3 (Replacement for the Brunitec GOLIATH 2000) is ergonomically friendly, easy to use and features a unique unloading system that separates the parts from the media as they come out of the machine, leaving the media in the machine!
