In contrast to conventional electropolishing, the DryLyte process removes material only from the peaks of surface roughness. The material removal is therefore relatively low, and the component geometry remains intact. / In contrast to traditional electropolishing systems, the DryLyte dry electropolishing process removes only the roughness peaks from the workpiece surface. Therefore, the material removal rate is very low. This ensures that the geometrical integrity of the workpieces is not affected. © Rösler

With dry electropolishing, perfect high-gloss surfaces can be produced reproducibly and resource-efficiently in short process times. / The dry electropolishing technology enables the reproducible and resource-saving generation of perfect high-gloss surfaces in short process times. ©GPA Innova

Frequently, this requires new finishing methods. With the DryLyte system Rösler Oberflächentechnik offers an innovat…

For the processing of femur implants, the new facility by Smith+Nephew currently has two manufacturing cells, each with three drag finishers. The automatic centrifuges for the preparation of process water are equipped with Rösler Smart Solutions' digital process water management system

The drag finishers R 6/1000 SF feature a processing bowl with a diameter of 1,000 mm and a carrier carousel for six work spindles. They are ideally suited for precise, selective individual processing of complexly shaped and damage-sensitive workpieces such as femur components. (Photo: Rösler Oberflächentechnik GmbH) / The drag finishers R 6/1000 SF consist of a processing bowl with a diameter of 1,000 mm and a carousel with six rotary spindles. Because the workpieces do not touch each other during grinding and polishing, RÖSLER drag finishers are ideal for the precise processing of delicate and complex high-value workpieces such as femur components.

The drag finishers were commissioned at the Rösler plant in Untermerzbach by Jürgen Preiser, Senior Manufacturing Engineer at Smith+Nephew, Johannes Schorr, and Sebastian Schuberth from the Rösler team (left to right). (Photo: Rösler Oberflächentechnik GmbH)

For the various implants, there are precise specifications regarding surface quality. For example, the outer surface of the femur components requires homogeneous, very smooth, and high-gloss polished surfaces, which necessitates partial processing.

For the targeted surface finishing of its hip stems, MBN Precision Technology replaces manual grinding with subsequent electropolishing with a two-stage, automated tumbling process. The Rösler tumbling finisher, model R 4/700 SF, enables the precise processing of up to twelve hip stems simultaneously. In addition to significant cost and time savings, this results in improved and reproducible quality. (Photo: MBN Precision Technology GmbH)

The hip stems are attached to a specially designed clamping device that can be universally used for all hip stem types and sizes. For the first finishing stage - wet grinding & pre-polishing – a mix of plastic media in combination with a special compound is utilized. (Photo: MBN Präzisionstechnik GmbH)
