What to Do When a Half Shaft Bends After Quenching? How to Solve Heat Treatment Deformation Problems of Automotive Half Shafts?

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.

Why Do Shaft Components Bend After Heat Treatment? How to Restore Straightness After Heat Treatment Deformation?

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.
