Optical coordinate measuring machine for small surface details on large components

µCMM, the first purely optical coordinate measuring machine (cmm machine), is used to measure extremely tight tolerances in high accuracy. Users combine advantages from tactile coordinate measuring technology and optical surface metrology:

measurement of dimension, position, shape and roughness with only one sensor
high accuracy over the entire measurement volume
non-contact, optical coordinate measurement with Focus-Variation
suitable for matte to highly polished components
easy handling
wear-free, robust and suitable for production

Highlights of the coordinate measuring machine µCMM

Precise, fast and flexible

5 axes metrology

The expansion from 3 to 5 axes allows measurements of geometries that are otherwise difficult or impossible to access. High-precision tilting and rotating axes enable the measurement of GD&T and roughness parameters on the entire measured object.

Lateral probing of flanks >90

Vertical Focus Probing

The latest technology enables the optical, lateral probing of components over the entire surface. Users measure holes and vertical flanks >90° with this CMM.

highly polished smooth surfaces

Advanced Focus-Variation

By using modulated illumination during the vertical scanning process, users not only gain a robust and high depth resolution, but also a significantly more robust and higher lateral resolution.

More than just optical coordinate measurement - what else is possible with µCMM

Software for applications in dimensional metrology

MetMaX: "What do I measure?" not "How do I measure?"

This is the core thinking behind MetMaX, the µCMM operating software. Thanks to this evolution, users do not need any specific metrology knowledge to perform robust measurements with the µCMM coordinate measuring machine. MetMaX contains all the necessary knowledge on how to acquire and evaluate 3D data.

Pick & Place: µCMM automation solution

The μCMM can be extended with a collaborative robot arm to a complete Pick & Place solution. Users thus achieve automatic placement, measurement and sorting of components (OK/not OK) in production. The possible connection to existing production systems including ERP facilitates adaptive production planning.

Full form measurement with Real3D

With Real3D, users realize complete geometry measurements of complex component geometries. Furthermore, the technology enables the analysis of complex profiles and measurement of flat and curved components as well as the verification of form deviations.
