Description

The Murua silver and brass electro-finisher delivers an easier, faster and more effective finishing option for jewelry pieces. Inside the finisher, prepared workpieces are immersed in a solution specially formulated for silver and brass (available separately) that coats the metal surfaces. The finisher, based on mechanical-galvanic principles, uses mechanical agitation to bombard the piece with tiny particles of plastic media. As they bump against the workpiece, the particles temporarily disturb the coating, allowing the charged bath to cause electrolytic depletion, polishing the metal surface—even the finest details and crevices of the design—in the fraction of a second before the coating is restored.
This compact, innovative machine is designed to handle silver and brass workpieces and produces higher-quality results faster and more easily than traditional mass-finishing methods.
• Load jewelry pieces onto the accessory hooks on the parts holder (fixturing unit) that fits into the power head; choose the holder and hooks (all available separately) that best accommodate the size and shape of the pieces you want to finish.
• Gemstones (at least 7 on the Mohs hardness scale) and non-metal components need not be removed; they are left untouched and unchanged by this process.
• Protect the geometry of your workpiece—traditional mass-finishing methods don’t polish at an even rate, resulting in rounded edges and muted details. This revolutionary system polishes at an even rate, protecting your design.
• Easily recover the precious metal that is removed in this process. There are no abrasives mixed with the metal—just scrape the dry cathode and send scrap to the refinery for metal recovery. No more trying to sweep up and collect dust filings—it’s all collected in the machine.
