  • Online display of the position of the scanner in the real coordinate system of the grinding machine.


Calibration mode

  • Automatic splitting of the roll into test zones.
  • Automatic generation of AVG-diagrams for each zone, taking into account the attenuation rate.
  • Determining the level of the bottom echo signal drop below the fixation level for each zone.
  • Viewing the results of testing in the 3D display of the mill roll with the spatial location of the defects.


  • The testing is performed as a technological stage after machining, grinding both newly manufactured and repaired mill rolls directly at the machining station, without transshipment.
  • Extension of service life of the mill rolls repaired as per the inspection results.
