Workpiece and material testing
For incoming inspection or after the completion of large components, we use measuring and testing methods to determine the quality of the workpiece. These tests are documented in accordance with the relevant standards.
We carry out a wide variety of workpiece, material and dimensional testing for our customers.
Laser tracking
With our mobile laser measuring system, we can also perform dimensional checks on components and precisely measure complex contours of large components.
Fully documented and traceable, we achieve the following accuracies with our laser tracker:
