Quality Controle Teststand | vQC

Description

Fully automatic high-precision test bench for determining natural frequencies and damping with interface to ProLINK

With the Quality Control Test Stand | vQC it is possible to determine the dynamic sizes (natural frequencies and damping) of various technical components fully automatically, to identify deviating parts and to mark/eject them.

This test is particularly essential for the final inspection of aluminum components (voids + coarse grain formation + geometric deviations), brake pads (pre-deviation + pad detachment) or brake discs (coating + cracks). In quality control in production, the dynamic sizes are characteristics that can be determined quickly. MAUL-THEET offers a complete system that carries out these measurements fully automatically, evaluates them and, if necessary, marks or ejects the component if it deviates.
