Watch a drive shaft — solid or hollow — move through automatic straightening in this video. The shaft is supported at its bearing seats, probes check runout at 2–3 key sections on shorter shafts and more on longer ones, and the hydraulic ram corrects bend in a measure–press–remeasure cycle tuned for the high volumes typical of driveline plants.
Cycle times run 20–90 seconds per shaft, fast enough to feed transmission and axle assembly lines, and the closed-loop control holds automotive TIR to 0.02–0.05 mm without relying on operator judgment. Splines, bearing journals and tube welds are protected by soft tooling. Our note on TIR measurement explains how this runout is inspected.
The machine serves propeller shafts, half-shafts and transmission shafts across passenger cars, trucks and off-highway vehicles, with diameter and length settings stored as part programs, and it outperforms manual floor-press straightening by a factor of 5–10. Hollow tube shafts and solid forgings run on the same supports, and the control accounts for their different springback behavior to keep results consistent across mixed production.
