Surface Inspection – RSIS

Reliable monitoring of the roll surface

For the automatic detection of roll surface defects, HCC/KPM offers the laser measuring device Roll Surface Inspection System (RSIS). In the post-process, RSIS records and evaluates the reflexion of a laser beam on the roll surface. Machining errors, such as chatter and infeed marks, commas, clouds and similar defects are reliably detected. Based on this information, a threshold analysis determines the surface quality of the roll. The threshold value can be individually set in accordance with roll surface quality requirements.

The test run is integrated in the CNC grinding program. Thus, each roll is inspected and no roll can be used unchecked. The constant monitoring of the roll surface quality minimizes unplanned roll changes – a production increase in the mill is the result.
