The Hommel-Etamic Roundscan form measurement system is used for the standard-compliant form and roughness measurement of rotationally symmetrical parts. Straightness, roundness, flatness, cylindricity, parallelism, perpendicularity, inclination, coaxiality, concentricity, axial run-out and roughness can be measured with this system on rotationally symmetrical components. Furthermore, 2-dim. roughness measurements, 2-dim. waviness measurements and swirl measurements can be carried out in predefined or self-defined measuring cycles.
