Roll scan inspection means that gears are scanned in rolling contact with a special inspection gear. The instrument combines the simple, robust and temperature stable design of the single flank gear rolling inspection with the greatest information density of modern coordination measuring technology, yet the measuring time remains short.

Using special pins in the inspection gears ensures a metrological favourable and thin line of contact with the workpiece. Several section planes on all flanks are measured during inspection. A complete topography of the gear flanks is then calculated from the sections.

100,000 measuring points can be taken within 2 minutes. This creates a measuring point grid on the gearing.

The evaluation software enables the user to view conventional charts but also modern area analyses and tolerance analyses on all gear flanks.
