Measuring takes centre stage in this clip: a shaft turns between centers while a scanning carriage moves along it, and the screen builds a picture of runout at each section before any pressure is applied. Only then does the head move — one calculated stroke per bend, followed by a fresh scan, on a guarded machine built for tight-tolerance work.
For high-speed rotors and EV shafts, a few hundredths of a millimetre decide bearing life and noise: general work holds 0.10–0.30 mm/m, automotive grade runs 0.02–0.05 mm, and the finest jobs come in at ≤0.02 mm. Reaching that on every part needs compensation built around how each steel springs back, not operator feel — the approach behind the article on springback compensation.
Users include spindle makers, EV drive-unit plants and motor builders feeding automated assembly lines, where the runout data logged for each shaft is as valuable as the part itself. Cells arrive as standalone CNC units or as lines integrated into the production flow, and guarding plus probe layout are reviewed against the real line during quotation. Layouts and loading options are shown in the CNC and automatic range.
If your prints call for automotive or instrument-grade runout, send them over and our applications team will confirm what the process can hold, free of charge. Contact our engineering team.
