High precision measurement of valve seat roundness

See how optical 3D metrology is used for the inspection of valve seats and seals how KENDRION (Villingen) GmbH uses optical measuring technology from Bruker Alicona to test the roundness of its valve seats with repeatable precision and traceability for optimum tightness. This also applies to small valve opening angles and tolerances in the one-digit µm range.
