The camera follows one workpiece from start to finish. A steel shaft is set between the work supports, turns under the measuring probes, and exits as a checked, in-tolerance part. Probes trace the rotating surface — two to three points on short shafts, five to eight on long ones — locating every bend. The ram strokes the worst bend, a fresh scan follows, and the measure-press-recheck loop continues until runout clears. Passed parts are discharged automatically; anything still out of tolerance is separated.
A complete loop runs 20–90 seconds per shaft — roughly 5–10 times the throughput of manual pressing, at a pace that never depends on the operator. Part recipes are stored in the control, so changeover between part numbers takes minutes. The engineering behind the sequence is in our overview of how a straightening machine works.
These machines target the parts that bottleneck after turning or heat treatment — transmission, motor, and gear shafts and long rotor bodies. Each unit is configured from the customer’s drawings: supports, ram force, probes, and loading matched to the part, with per-piece runout logging optional. Power is 380–480 V three-phase; delivery runs 60–120 days. For sizing decisions, see the shaft straightening machine buyer’s guide.
Titles like ‘our shafts never come out straight’ usually end with a drawing review: send shaft prints and volume, and our engineering desk will assess straightenability, cycle time, and layout at no cost — contact us to start.
