A long steel shaft dominates this video, and scale is the point: supports, probes, and press travel are spaced for a part several meters long. The shaft turns while probes read it at five to eight stations — short parts need only two to three. The ram indexes to the largest bend, presses with a force set for the section, and probes re-read immediately. Correction repeats until the full length clears tolerance; the shaft is then unloaded to the out-feed and the next blank takes its place.
Long parts change the geometry of straightening: supports must carry the shaft’s own weight, and probes at five to eight stations are what stop a mid-span bend hiding between checks. On heavy sections the frame itself scales up, into the 1000-ton class, while the loop still runs at 20–90 seconds. Background is in our note on how the straightening machine works.
Railway axles, wind-power rotors, and heavy sections sit at one end of the range, small motor and gear shafts at the other; stored recipes handle both. Options include automatic loading, per-piece runout records, and remote diagnostics. Supply is 380–480 V three-phase and delivery runs 60–120 days. Standard builds are on the automatic straightening machines page.
Wondering whether one machine can carry your smallest pin and longest axle? Attach both prints, and we will answer in writing with the frame size, supports, and probe layout the spread requires — email the factory.
