The display beside the machine is this video’s subject: it shows total indicator reading falling stroke by stroke. A shaft is loaded and rotated while probes capture runout at several stations — two to three on the compact parts featured, five to eight on longer workpieces — then the ram presses the located peak bend. Probes re-read after each stroke and the number updates on screen; the loop ends only when it meets the target saved for that part number, and the verified shaft is unloaded.
Those targets cover the usual drawing requirements: 0.10–0.30 mm/m for general shafts, 0.02–0.05 mm for automotive components, and ≤0.02 mm for precision work, all achieved by measured iteration rather than operator skill. Watching the number converge is also a practical demonstration of why multi-point probing matters on long parts. Our runout (TIR) measurement explainer defines each value.
Buyers choosing their first machine — job shops, repair workshops, and small production lines — use this entry of the range for gear shafts, motor shafts, piston rods, and lead screws in varied volumes. Manual-load CNC models start the range, with gantry loading and data logging added as needed; supply is 380–480 V three-phase and delivery 60–120 days. The full selection logic is in our shaft straightening machine selection guide.
First-time buyers ask what to send: a print, annual quantity, and a tolerance question suffice. Our applications desk answers the entry-level or automatic decision plainly, and the first review carries no charge, through our contact page.
