At Buell Automatics, we know that aerospace machined parts don’t just need to fit. They need to perform. There’s no room for error when an aircraft is 30,000 feet in the air. Every component, from turbine blades to landing gear, must withstand extreme forces, temperatures and stresses while maintaining exact dimensions.
So, what does it take to produce aerospace machined parts that meet these sky-high standards? Let’s break it down.
Tolerances That Leave No Margin for Error
In aerospace, even a fraction of a millimeter can make the difference between smooth operation and catastrophic failure. Parts often need tolerances tighter than ±0.0005 inches, meaning measurements must be near-perfect every time.
How do we achieve this?
- Rigorous Inspection: We use tools like Oasis vision systems, Keyence Image Measuring system and Starrett comparators to verify dimensions at every stage, catching deviations before they become problems.
- Process Discipline: Our machinists follow strict protocols to minimize variables, from tool wear to thermal expansion.
- Experience Matters: Since 1966, we’ve tackled tricky tolerances for aerospace, automotive, medical and defense applications, learning what works and what doesn’t.
Lightweight Materials, Heavyweight Challenges
Aircrafts need to be light to fly efficiently, but strong enough to handle turbulence, landing impacts and engine stresses.
That’s why aerospace relies on materials like:
- Aluminum alloys: Easy to machine but strong enough for structural components.
- High-strength steels: Durable and impact-resistant for critical load-bearing parts.
- Advanced composites: Offering exceptional strength-to-weight ratios for modern airframes.
Working with these materials requires precision expertise. Aluminum alloys, while more forgiving than some metals, still demand careful machining to prevent tool chatter and maintain dimensional accuracy. Our team knows how to optimize feeds, speeds and cooling to ensure consistent results with these aerospace-grade materials.
How Buell Automatics Delivers
Meeting aerospace demands isn’t just about having the right machines, though 5-axis CNCs help. It’s about how we use them.
No Guesswork in Materials
We’ve machined everything from aluminum to exotic alloys, so we know how each behaves under the tool.
Inline Inspection
Parts are checked throughout production, not just at the end, so issues are caught early.
Compliance You Can Trust
We are ITAR-compliant and ISO 9001:2015-certified.
The Bottom Line for Aerospace
When lives depend on your parts, you need a machinist who understands the stakes. At Buell Automatics, we combine 50+ years of experience with the discipline to deliver aerospace machined parts that perform when it matters most.
