This demonstration focuses on accuracy rather than speed, and the camera keeps returning to the measurement. A shaft is loaded on its supports and turns while contact probes read it at two to three stations — five to eight for long parts — and the control highlights the worst bend on screen. The press ram applies a controlled stroke to that point, the probes re-read immediately, and the loop continues until the displayed runout sits inside the target band. The part is then unloaded with its final measurement logged.
What the screen demonstrates is how runout is specified: drawings quote 0.10–0.30 mm/m for general parts, 0.02–0.05 mm for automotive, ≤0.02 mm for precision — and the machine reaches each band by iteration instead of a single lucky stroke. Verified parts also reduce incoming inspection downstream. Our guide to shaft runout and TIR translates drawing symbols into these numbers.
Makers of servo motor shafts, spindles, and ball screws typically specify the tighter bands; general engineering shops use the same machine at the wider setting. Capacity runs from Ø5 to 600 mm and 100 mm to 12 m, with frames up to the 1000-ton class. Supply is 380–480 V three-phase; delivery 60–120 days. Standard models are shown in the automatic machine lineup.
A runout callout on the print starts a precision conversation: state the TIR symbol, surface, and datum, and our metrology desk confirms the achievable band and seconds per piece through use the inquiry form.
