Aerospace Industry
We understand the importance of surface finishing for aerospace engines, and have worked closely with major manufacturers in the aerospace industry to adapt and develop finishing solutions that meet their stringent requirements. Tests have proven that our finishing solutions reduce processing times and deliver consistent, high-quality results, benefiting the industry as a whole
Using ActOn's vibratory finishing machines, centrifugal high energy finishing machines, our precision polishing facility and ActOn's aerospace finishing consumables, our engineers have developed cost-effective finishing applications for parts such as: forged compressor blades, fan blades, rotor and stator blades, turbine blades, blade assembly, vane rings, annulus fillers, turbine segment, side stays, landing gears, structural parts and much more.
Technology We Recommend
Case Study
Aerofoils
The end result is an aerofoil with an average right-first-time of 92.7%, delivered to a high standard in a considerably reduced time. The dimensional integrity of the part was maintained, whilst all defects on the surface were completely removed.
VIEW ALLAerospace Surface Finishing Solutions for Critical Components
Surface finishing in the aerospace industry is not cosmetic. It directly influences fatigue life, aerodynamic efficiency, coating adhesion and component reliability.
ActOn Finishing delivers aerospace surface finishing systems engineered for precision, repeatability and dimensional control across safety-critical components.
Our finishing technologies are applied to:
- Forged compressor blades.
- Fan blades.
- Rotor and stator blades.
- Turbine blades.
- Aerofoils.
- Landing gear components.
- Structural aerospace parts.
Every aerospace component demands controlled surface roughness reduction while maintaining dimensional integrity — a requirement clearly demonstrated in our aerofoil case study.
ActOn Finishing also provides precision polishing and inspection subcontract services for aerospace components, supporting manufacturers during development and production.

Controlled Surface Roughness for Aerospace Standards
In aerospace applications, surface finish is often specified in precise Ra or Rz values.
Controlled surface finishing improves:
- Fatigue resistance.
- Airflow efficiency.
- Coating performance.
- Crack initiation resistance.
- Corrosion protection.
Centrifugal high energy finishing and vibratory finishing systems enable uniform material removal across complex geometries, ensuring surface consistency without edge rounding or profile distortion.
For aerospace engines, this level of control is essential.
Materials Processed in Aerospace Finishing
ActOn systems are configured to process aerospace alloys including:
- Titanium alloys.
- Nickel-based superalloys.
- Stainless steels.
- Aluminium aerospace grades.
- High-strength structural materials.
Each material requires specific abrasive media, cycle control and finishing chemistry to achieve performance without compromising metallurgical properties.
Scalable Finishing for Aerospace Production
As aerospace manufacturing scales, finishing processes must transition from manual refinement to measurable, repeatable systems.
Industrial aerospace surface finishing systems provide:
- Batch consistency.
- Controlled cycle times.
- Multi-part processing capability.
- Reduced operator variability.
- Traceable process parameters.
This enables aerospace manufacturers and Tier 1 suppliers to maintain quality assurance across production volumes.
