The rolls are exposed to high loads, especially in rolling mills in the steel industry.
Using crack detection technology, the rolls can be checked during the grinding process in order to avoid unplanned production downtimes.

For crack detection, we use the technology of our well-known supplier LISMAR . LISMAR has the necessary KNOW-HOW and has equipped many of the METEX roll grinding machines with its systems. 

The pure eddy current technology detects cracks on the cylinder surface.
Combined systems with additional ultrasonic measuring heads are used to record defects and structural changes below the roll surface.
