The Aluminum Machining Challenge

Understanding why aluminum alloys deform during machining and how it impacts your production

Built-up Edge and Chip Adhesion

During high-speed machining of aluminum alloys, at lower cutting speeds, chips tend to adhere to the tool edge, resulting in a rough tool surface.

Residual Stress Problems

Internal stresses from raw material processing are released during machining, causing unpredictable deformation in finished components.

Thin-Wall Distortion

Lightweight designs with thin walls are particularly susceptible to vibration-induced deformation and tool pressure distortion.

Frequently Asked Questions

Expert answers to common aluminum machining deformation questions

What aluminum alloys are most prone to machining deformation?
High-strength alloys like 7075 and 2024 are particularly susceptible due to their residual stresses, though all aluminum alloys can experience deformation without proper machining protocols.
How do you prevent thin-wall distortion in aluminum parts?
A: We combine specialized tool paths, reduced radial engagement, custom fixturing, and controlled machining sequences that minimize vibration and thermal effects on thin features.
Can you machine large aluminum parts without warping?
A: Yes, through our multi-stage machining approach with intermediate stress-relieving cycles, we consistently produce large aluminum components with flatness tolerances under 0.1mm/m.
What tolerances can you maintain on aluminum parts?
A: With our deformation-control processes, we routinely achieve ±0.025mm dimensional tolerances and 0.05mm flatness on critical aluminum components.
