Objective

An aerospace customer sought to enhance the surface finishing of their CNC-machined compressor blisks, fabricated from stainless steel alloy. The existing method, extrude hone abrasive flow, was costly, labor-intensive, and yielded suboptimal surface finishes. The goal was to implement a more efficient, cost-effective process using a drag finisher to achieve superior surface quality.

Solution

Bel Air Finishing recommended a Drag Finisher to replace the extrude hone abrasive flow process. This high-efficiency method securely clamps the compressor blisks and moves them through a process drum with specialized media, achieving a uniform, refined surface. The drag finishing process significantly reduced manual labor, improved surface quality, and lowered operational costs while ensuring the components met stringent aerospace performance standards.
