Industry: Aerospace
Application: Aerospace Turbine Blade Surface Preparation and Controlled Shot Peening
In the aerospace industry, turbine blades are the heart of aircraft engine performance. Operating under extreme thermal and mechanical stress, these components demand flawless surface integrity to prevent premature fatigue and failure. Whether you are an original equipment manufacturer (OEM) or a Maintenance, Repair, and Overhaul (MRO) facility, achieving precise, repeatable surface finishing on turbine blades is critical to ensuring flight safety and engine efficiency.
At Empire Abrasive Equipment, we engineer automated air blasting and shot peening solutions that meet the aerospace industry’s most stringent quality standards at high production volumes.
The Challenge: Balancing High Volume with Rigid Aerospace Standards
Aerospace engine components leave no room for error. When processing complex geometries like turbine blades, manufacturers face a demanding trifecta of requirements:
- Exceptional Process Repeatability: Every blade must receive the exact same treatment, regardless of production volume.
- Precise Coverage Control: Critical blade features require highly targeted surface preparation and shot peening.
- Stringent Quality Compliance: Meeting rigorous aerospace specifications (such as AMS2430 or automated blast standards) requires absolute control over variables like blast pressure, media flow, and cycle times.
Enormous manpower is required for manual blasting to deliver the uniformity required for these critical applications, forcing many in the industry to seek sophisticated, automated alternatives.
Our Solution: Automated Indexing Turntable Systems
Aerospace manufacturers worldwide have incorporated Empire Indexing Turntable Machines into their production facilities to automate surface finishing of aerospace turbine blades.
Custom engineered fixturing and advanced process controls ensure that each blade receives consistent, uniform exposure to the blast stream. To maximize efficiency and optimize performance, we configure separate process setups tailored to the two primary stages of turbine blade finishing:
- Surface Preparation Prior to Coating – Before thermal spray or thermal barrier coatings (TBC) can be applied, the turbine blade surface must be perfectly etched to ensure optimal coating adhesion. Our Indexing Turntable Automated Blast Systems provide a highly consistent anchor profile, eliminating the risk of coating delamination.
- Controlled Shot Peening Operations – To increase fatigue strength and resist stress-corrosion cracking, critical blade root features must undergo controlled shot peening. Our precision controls allow for tight monitoring of shot intensity and coverage, ensuring compliant compressive stress layers every time.
The Results: Reliable, High-Volume Compliance
Our automated turbine blade processing systems are currently utilized by many of the world’s leading aerospace manufacturers to streamline their surface finishing workflows. By transitioning to an Empire automated solution, aerospace facilities consistently achieve:
- Unmatched Repeatability: Highly predictable, automated blasting and peening results that eliminate operator error.
- High-Volume Throughput: Efficient indexing configurations designed to keep up with demanding production schedules.
- Guaranteed Quality Assurance: Robust process tracking that supports reliable compliance with aerospace manufacturing specifications.
