Dimensional inspection using a specialised measuring arm – with 3D imaging

We carry out precise measurements of components and structures using a portable, 7-axis measuring arm equipped with an AS1 laser scanner.

The mobility of the entire system allows measurements to be carried out directly at the customer’s premises. The technology provides point measurement accuracy of up to 0.006 mm and enables a three-dimensional image of the measured component to be obtained.

Our specialised dimensional inspection services include, among others

measurement of component dimensions and geometry

non-contact surface scanning

creation of three-dimensional 3D images

inspection of the shape and relative position of surfaces

verification of component compliance with documentation

measurement of components longer than 2,500 mm

Applications of 3D dimensional inspection

Dimensional inspection using a measuring arm is suitable wherever high accuracy, rapid measurement and the capability to precisely reproduce even more complex shapes are essential.

The service is suitable for measuring, among others

components of steel structures

parts of machines and equipment

production parts and prototypes

components with irregular shapes

larger industrial components

parts requiring precise dimensional inspection
