- Macro lead measurement: MBN 31007-7
- Micro lead analysis according to the IMA method (Institute for Machine Elements, University of Stuttgart)
- Roughness measurements: DIN EN ISO 13565
- Scratches and defects: DIN EN ISO 8785
With LEADinspect, macro lead and micro lead are analyzed in one metrology system. The user thus obtains a quantitative evaluation of lead structures (Lead Analysis) which could previously only be recorded using the thread method. Data about the stochastic arrangement of roughness elevations (Roughness Measurement) on the surface are also obtained. The distribution of these roughness elevations influences the service life of a radial shaft seal and thus determines the suitability of the surface as a sealing surface.
The shell surface is also scanned by flat measuring fields, which allows an evaluation of waviness. Macro lead is evaluated according to the current version of the Daimler standard MBN 31007-7. The FVA guideline 975 I is being implemented, which sets a new standard for lead measurements.
In addition, LEADinspect can measure roughness according to DIN EN ISO 4287, 13565 and 25178 and analyzes the dominant waviness in accordance with VDA 2007.

- Short measuring times thanks to area image capturing
- Lateral resolution: less than 0.25µm; height resolution according to VDI 2655: less than 3nm
- An image field size of 630x630 µm enables a highly accurate quantitative statement about the conveying structures of the surface and a visual statement about the surface condition
- Analysis of macro and micro lead in one metrology system
- Correlates with the results of tactile measuring systems in the evaluation of the macro twist according to the Daimler standard
- Micro lead measurement: 18 circumferential and 3 axial measuring points are scanned and analyzed (a total of 54 measuring points on 630x630 µm)
With LEADinspect, roughness, stochastic distribution of roughness elevations, surface damage, macro lead and micro lead are scanned and evaluated in a single measurement. The data are available to the user in a form that can be used for later correlation investigations with endurance run evaluations and returns from the field.
The confocal optical measurement method (Structured Illumination Microscopy) developed and patented by Confovis does not use laser scanning or moving components such as mirrors or multi-pinhole disks. The 3D scanning takes place in focal planes by means of a structured illumination sequence. In contrast to established confocal measurement technology, the metrology system does not scan a surface point by point or line by line, but over a wide area.
For a comprehensive, user-friendly and reliable evaluation, LEADinspect uses the leading analysis software MountainsMap® from Digital Surf, as well as the micro-twist analysis from IMA combined in one measurement sequence. This provides the user with evaluations according to established standards and archivable results without extensive user knowledge, which of course meet the requirements of Industry 4.0.
The LEADinspect metrology tool combines high-precision measurement technology with a robust design (vibration-damping base and granite machine frame) and can operate directly in production environments.
Samples up to 250 mm in flight circle diameter, 550 mm length and up to 15 kg weight can be measured without contact.
Smaller and larger systems are also available.
