Crab Bracket

To smooth and polish EBM-printed aluminum crab brackets, removing surface imperfections such as “stair-stepping” to improve the finish quality and make the part market-ready for aerospace applications.

Bel Air Finishing collaborated with Alloy to test the Centrifugal Disc Finisher as a high-energy finishing solution for EBM-printed aluminum crab brackets. This process smooths and polishes the surface, effectively eliminating the “stair-stepping” texture typical of 3D-printed parts. The resulting uniform finish enhances the bracket’s aesthetic and functional qualities, aligning it with aerospace standards. By reducing the need for manual post-processing, the Centrifugal Disc Finisher provides an efficient, precise solution that helps manufacturers accelerate production timelines and deliver high-quality components to market.

If you are unsure what equipment and media you require to achieve your desired surface finish, then send us your part, and we will evaluate it and provide you with a metrology report.
