Process Technology – Surface Finishing

For over 50 years, Bel Air Finishing has pioneered advanced mass finishing solutions designed to meet diverse surface finishing needs across industries worldwide. We offer a full range of processes tailored to your application, including vibratory tumbling for gentle finishing, drag finishing for complex geometries, and high-energy centrifugal disc and barrel finishing for rapid, precision results. Additional solutions like wet grinding, dry polishing, blasting, and superpolishing address the most demanding finishing challenges.

Whether your goal is deburring, polishing, edge preparation, or surface preparation for coatings, our team develops customized processes to deliver optimal performance. We adapt our technologies to meet your part specifications, ensuring consistent quality and efficiency.

To guarantee superior results, we provide free sample processing. Our advanced metrology tools, including non-contact 3D white light interferometry, measure and document before-and-after surface data. Our detailed metrology report includes 3D imagery and Ra and Sa surface roughness values, offering full confidence in the process.

Once you are satisfied with the results, we quote the necessary equipment, media, and compounds to replicate the process at scale. We also offer post-sale support, including media replenishment, maintenance, and process optimization, ensuring your finishing system continues to meet evolving production needs.
