Chassis giga-casting 3D straightening framework: why castings move, what makes correction three-dimensional, datum and fixture strategy before correction, conce

Automatic hexagonal pin straightening with optical screening and closed-loop correction: angular orientation, non-round measurement models and bypass architecture.

Long ball stud straightening for cold-forged blanks: roller vs point-press selection, ball head and transition protection, stage decisions and sample-test evidence.

Leaf spring straightening and camber correction: free camber vs side bend vs loaded height, protected eyes and peened surfaces, press routes and pack load testing.

Front fork tube straightening between hardening and chrome plating: thin-wall support rules, ovality vs bend separation, protected zones and released verification.

CV joint and tripod shaft straightening for bare barrels and tripod stubs: trunnion datums, protected raceways and splines, multi-mode deformation mapping and stroke strategy.

Rocker arm straightening as geometry restoration: the datum chain from pivot bore to pads, four deformation modes, micro-press correction and vision-based acceptance.

Shift fork shaft straightening for hardened grooved rails: datum selection, groove masking, protected contact maps, per-lot springback recipes and closed-loop correction.
