Aluminum Concept Car Components – Deburr, Surface Prep

A customer needed to reduce the high volume of manual polishing required for CNC-machined aluminum 7075 concept car components. For this specific component, the focus was on automating deburring and surface preparation prior to plating—while minimizing edge distortion and improving consistency across curved, contoured features.

Bel Air implemented a vibratory finishing to automate deburring and surface smoothing of CNC-machined aluminum 7075 concept car parts. For this part’s curved geometry and tight interior radii, Bel Air fine-tuned the media and compound combination to effectively remove tool marks and soften edges without affecting dimensional integrity. The result was a consistent surface finish, reduced hand labor, and reliable plating prep—critical for visual components in low-volume production runs.

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.
