Follow-up Order for Herkules in Kazakhstan

One of our long-standing customers has once again decided to place its trust in the reliability and expertise of Herkules when modernizing its machinery: Within the scope of the project, a total of eight machines – four for the cold rolling mill and four for the hot rolling mill – are completely replaced by state-of-the-art Herkules roll grinders equipped with cutting-edge roll inspection and measuring systems.

“We are delighted about this follow-up order, which came about after the purchase of a Herkules texturing machine type PTM 500 in 2022. Our customer now wants to work with us to modernize its roll grinding shop,” explains Andreas Bongardt, Sales Director for Eastern Europe and the CIS.

The combination of Eddy Current and Ultrasonic enables reliable localization of open cracks on the roll surface and changes in the roll structure. “Thanks to our in-house developed measuring systems, corrections can be made on the fly, which drastically reduces grinding times. Accuracies are significantly increased and at the same time wear on grinding wheels and roll material is significantly minimized. This increases the service life of the rolls in operation and significantly reduces operating costs,” Andreas Bongardt continues.

Another advantage of the upgrade at our customer‘ s facility: The modification of the grinding process of all work rolls and back-up rolls in chocks is now possible. Thanks to this upgrade, bearing damage can be prevented and rolls can be returned to operation more quickly. “Bearing damage is mainly caused by the removal and reattachment of chocks. The smallest inaccuracies during de-chocking lead to damage of the rolls or bearing surfaces and even to premature rejects. This will no longer be an issue for our customer in future,” concludes Andreas Bongardt.
