aluminum pipe/tube bending
Aluminum tubing often bows due to residual stress or handling. Learn repeatable straightness checks, safe correction methods, when to scrap, and when automation pays off.
Expert insights on hydraulic straightening technology, industry trends, and best practices.

Alloy bars bend from residual stress or handling. Learn to verify runout, use hydraulic straightening for controlled deviations, and avoid risky fixes.
One inspector says a shaft is fine at 0.20 mm. Another rejects the same part at 0.25 mm.
When a machined 4140 shaft or bar comes out of heat treat with a visible bow, it's easy to blame the quench.
The machine measures the shaft’s runout at multiple points, calculates the exact press stroke and position needed, and applies force in a closed loop—often reaching straightness within 0.01 mm.
Runout that was within 0.02 mm before heat treat suddenly jumps to 0.3 mm, 0.5 mm, or worse. It’s one of those headaches every production shop knows.
