Three operators, three different results on the same shaft: that inconsistency is what an automatic straightener is built to eliminate, and this clip shows how. The shaft is loaded, spun under probes that mark every bend, and pressed at the peak points under CNC control. After each stroke probes re-measure and decide the next move, so the machine converges on the same target whether the batch is soft or hardened. The accepted part is unloaded to the out-feed; the controller keeps the measured runout on file.
A full loop takes 20–90 seconds — bend count and length decide where — and runs 5–10 times faster than a skilled hand-press operator, with no pace loss across shifts. Accuracy holds the same verified bands every time: 0.10–0.30 mm/m general, 0.02–0.05 mm automotive, ≤0.02 mm precision. Background is in our overview of how a straightening machine works.
The machine fits shops whose part mix includes motor shafts, pump shafts, compressor shafts, and hydraulic rods across small and medium batches, where recipes replace operator know-how between changeovers. Manual loading suits low volumes; gantry or robotic feed can be added as production grows. Power is 380–480 V three-phase and built-to-order delivery runs 60–120 days, with training and remote support. See standard builds on the automatic straightening machines page.
Consistency complaints usually vanish once recipes replace craft. Pick two or three recurring part numbers, send their prints, and we will size one machine covering all of them with stored recipes — contact our engineering team with the files.
