Aerospace/Defense Process Technology Examples

Aerospace components must meet strict surface quality, durability, and precision standards to ensure optimal performance and compliance with industry regulations. Bel Air Finishing provides aerospace surface finishing and metal finishing solutions for turbine blades, compressor discs, and structural components. Our precision deburring, polishing, and surface preparation processes enhance aerospace finishes, improving fatigue resistance and overall part longevity for high-performance applications.

Automated finishing ensures aerospace components meet the highest standards of consistency, safety, and durability. Even a minor burr or surface defect can create stress risers that compromise fatigue resistance, shorten service life, or lead to premature part failure.

Manual deburring and polishing are not only inconsistent, but also labor-intensive and difficult to validate at scale. Bel Air’s automated systems — including drag finishing, vibratory deburring, and slurry wet blasting — provide repeatable, documented results. These processes deliver finishes that meet or exceed required Ra specifications, improve edge quality, and reduce stress concentrations. They also support compliance with FAA, NADCAP, and OEM specifications, giving aerospace manufacturers confidence in both quality and audit readiness.

Aerospace manufacturers rely on a range of finishing methods, each selected based on part geometry, material, and performance requirements.

  • Turbine blades and compressor discs often require isotropic finishing, superfinishing, or ultrapolishing to reduce friction, improve airflow efficiency, and extend engine life.
  • Structural components like brackets, landing gear, and housings may undergo slurry wet blasting, anodizing, or conversion coating for corrosion resistance.
  • Electronic connectors and housings benefit from vibratory deburring or electropolishing to improve conductivity, ensure reliable fit, and prevent premature wear.

Bel Air works with aerospace OEMs to build the right machine for each component. By matching material type (e.g., titanium, Inconel, stainless steel, aluminum alloys) with the appropriate technology, we ensure consistent, high-performance surfaces across both machined and additive-manufactured parts.

Yes. Bel Air specializes in finishing both traditional aerospace alloys and next-generation additive components.

We routinely process titanium, Inconel, stainless steels, aluminum alloys, and composites — materials valued for their strength-to-weight ratio and durability but known for being difficult to machine and finish. Our technologies are engineered to handle these challenging materials while maintaining tight tolerances.

For additive manufacturing, we provide complete post-processing solutions. This includes removing powder residues, smoothing rough or layered surfaces, preparing parts for coatings, and ensuring dimensional accuracy. Bel Air also delivers a feedback loop from the finishing process, back to the printing operation, in order to maximize print productivity.
