The EF Flex is an innovative new electropolishing machine for yellow, red and white gold plus silver. This electropolishing unit enables filigree jewelry rings to be ground and polished in the shortest possible time. Intricate details remain intact and internal contours receive an excellent finish. Manual polishing is reduced to a minimum and the quality of your surfaces is greatly enhanced. Thanks to its modular design, the machine can be subsequently expanded to up to three individually controllable process tanks. The software includes a database in which workpiece specific process parameters can easily be stored and managed.
