Measurement with 3D profilometer. Stops and positioning aids realized with 3D printing or magnets.


  • Verification of the required surface roughness of purchased parts from different suppliers.
  • Determination of the value Rz according to ISO 4288, e.g. Rz < 100µm
  • Additional determination of the surface roughness Sa (average height/roughness) and Sz (maximum height/roughness)
  • Images of the scanned depth profiles from different views
  • Large number of measurements to cover all product variants


  • Measurements with Keyence 3D profilometer
  • Automated calculation of the values Rz, Sa and Sz
  • Accurate documentation of the measurements and presentation of the results in a report
