The footage starts with what buyers ask about — a visibly bent steel shaft — and follows it until straight. It sits on the supports and rotates while probes trace two to three points on the short body shown; longer workpieces use five to eight. The CNC turns the peak bend into position, the ram presses with a metered load, and probes re-check at once. If residual runout remains, another stroke is calculated from the new reading; once it clears, the shaft unloads and the cycle repeats.
Nothing in the loop is left to judgment: the press never assumes a stroke worked, which is how it handles bent stock with unpredictable springback after heat treatment. Finished runout is measured to 0.10–0.30 mm/m general, 0.02–0.05 mm automotive, and ≤0.02 mm precision. Our runout (TIR) measurement explainer shows how those numbers are defined and checked.
Frequent part-number changes define the shops that buy this version: motor shafts, piston rods, and lead screws moving through in small lots, with recipe-based changeover between them. Layout, automation, and force — including 1000-ton-class frames — are built to order, with training and overseas commissioning. Supply is 380–480 V three-phase and shipment comes in 60–120 days; see our guide for shaft straightening machine buyers.
The worst part in your rack is the best to ask about: send its print with incoming runout, and our engineers will outline the probe points and correction strategy before any quotation — details via our contact page.
