Machining tolerances of ±0.005 mm are routinely achieved to ensure tight fits.
Computer Numeric Control (CNC) mills and lathes are used to maintain dimensional stability.
Advanced Materials and Specialized Tools
Common materials include titanium, Inconel, aluminum-lithium, and CFRP.
Tool materials like cubic boron nitride (CBN) and polycrystalline diamond (PCD) are essential to handle such demanding materials without wear.
Best-in-Class Process Monitoring
Sensors track vibration, chip load, and temperature in real time.
Adaptive control systems adjust feed and speed mid-process to prevent errors or tool breakage.
How Does Aerospace Machining Overcome Complex Geometries?
5-Axis Machining Capabilities
Complex airfoil shapes and ribbed wing components are machined with simultaneous five-axis control.
Enables minimal tool repositioning and superior surface finishes.
Hybrid Additive + Subtractive Approaches
Engineers often produce near-net parts via additive manufacturing and then finish with high-precision machining.
Combines design freedom with tight tolerance capability.
Specialized Fixturing and Workholding
Custom vacuum and hydraulic fixtures are developed to hold delicate thin-walled parts securely.
These fixtures prevent deflection during machining, ensuring consistent part quality.
What Benefits Do End Users Gain from High-End Machining?
Enhanced Safety and Reliability
Parts machined with high consistency reduce the risk of in-flight failures.
