Filmic Contamination Leads to Gearbox Failure

The determination of the technical cleanliness according to VDA-19.1 or ISO-16232 is now an integral part of quality control and error analysis - because the cleanliness of components is decisive for the quality and error-free function of the product. In addition to particles, filmic contamination poses a problem, as the following example from quality assurance in the manufacture of electric drive systems shows.
