| The device measures and evaluates in an automatic cycle the circularity, cylindricity, run-out, coaxiality, perpendicularity and other characteristics with precision of 0,07 micron. |
| The MMQ 400 series supports fully automatic measurement of form and positional deviations as per ASME Y14.5 such as roundness, straightness, parallelism, coaxiality, run-out, cylindricity, and taper. |
| A primary measurement of form deviations such as roundness, cylindricity, straightness or flatness requires the realisation of measurement systems which can reproduce these forms without reference to any physical artefact. |
| Calibration of roundness, straightness, flatness, cylindricity, parallelism and squareness of form standards and gauges. |
| At the NMIA, the biggest challenge is still the polishing of the electrode bars to near-perfect cylindricity within 100 nm over a length of nearly 50 cm. |
| However, currently there is no quantitative and systematic way of assigning circularity and cylindricity tolerances. |
