ERLANGEN, Germany and CASTELLANZA, Italy, July 7, 2026 – Pomini Tenova and Siemens are expanding their work on roll grinder modernization for rolling mills, combining CNC-based controls, drive systems, automation, digital monitoring, diagnostics and predictive maintenance.
The partnership focuses on revamping existing roll grinders rather than replacing them. The companies said the upgrades are intended to extend machine life while updating control, automation and digital functions.
Pomini Tenova, the OEM, will provide roll grinding, inspection, roll shop automation and digital systems. Siemens will provide CNC-based control systems, drives and automation technology for machine tools, along with safety and cybersecurity functions.
The companies are also working toward more autonomous roll grinder operation. The approach combines Pomini Tenova’s mechanical upgrades and process-specific accessories with Siemens technologies for monitoring, diagnostics and predictive maintenance.
The revamping work will support process optimization using Industrial AI-based features. The companies said the upgrades are intended to reduce downtime, improve safety and maintain grinding quality throughout the machine operating life.
“Strengthening our collaboration with Siemens allows us to offer customers comprehensive revamping solutions that go beyond mere equipment upgrades, towards a truly AI-powered autonomous operation,” said Paolo Gaboardi, executive vice president, Pomini Tenova. “By integrating Siemens’ advanced automation and digital technologies with our roll grinder-specific solutions, we help customers improve long-term competitiveness and enable them to differentiate from the competition.”
Sascha Fischer, vice president sales for Machine Tool Business at Siemens, added: “Together with Pomini Tenova, we transform roll grinders by upgrading the machine’s CNC core. At the same time, we combine deep domain expertise with advanced digital and future-proof automation technologies, as we do with new machines, for which we also take advantage of including Siemens’ most comprehensive Digital Twin. This approach enables more autonomous operations and unlocks new value from customers’ existing assets”.
