“3D surface roughness, topography, and wear volume measurement.”

Optical 3D surface topography for Mechanical Components and Tribological Research

NanoFocus’ contactless measurement technology is capable of analyzing wear or material characteristics and has a broad range of applications, from tool making to engine development.

A new standard in optical 3D surface inspection.

uSurf microscopes are confocal 3D microscopes that can measure various samples in accordance with international standards including ISO 25178 and ISO 4287. uSurf microscopes are optimized for use in development and testing laboratories where roughness, geometry, flatness, wear volume, and bearing ratios need to be determined. uSUrf microscopes fulfill the highest requirements in the field of non-contact surface metrology, setting a new standard.

Accurate reproduction of the profile of ultra-fine roughness structures was a major criterion of the development of confocal measurement technology. Accurate reproduction is now an essential characteristic that allow uSurf microscopes to be uniquely suited as measurement devices in testing laboratories and quality control.

Quantify and qualify roughness, waviness and wear volume.

At the heart of the analysis is the topographic measurement of surfaces and the quantitative analysis of roughness, geometry, and wear volume. NanoFocus’ contactless and nanometer precise 3D measurement technology, uSurf, is in use by leading manufacturing companies and institutions for evaluation purposes.

Examples of application

uSurf’s 3D measurement systems allow for quality assurance near production lines. uSurf’s 3D capabilities allow samples with awkward characteristics, such as steep slopes, to be measured and return exact and precise 3D measurements in just a few seconds.

 

 

Engine cylinder walls inspection with µSurf Cylinder

uSurf Cylinder is capable of capturing the surface topography of cylinder bore surfaces, down to the nanometer. It yields qualitative and quantitative data in the wear and defects on the cylinder wall. This measurement data enables the analysis of honing structures, exposure depths, standard roughness values, surface roughness, and the wear volume after testing.

 

Portable 3D instrument for lab, production, and field applications 

uSurf Mobile is a mobile optical 3D measurement system developed especially for the measurement of large objects in rough environments. The entire surface measurement system weighs only 5.5 kg (12 lbs.), has an integrated autofocus, and can be readied for on-site use within a few minutes. Its features make uSurf Mobile ideally suited for applications in the lab and field and along the whole industrial process chain.

 

Machine components inspected with µSurf Explorer

Surface finishing has typical grinding structures. The roughness according to DIN, EN, or ISO standards can be determined based on a profile section as a benchmark. uSurf Explorer can determine evidence of wear, defects, appearance, and the directional dependence of roughness.
