Instead of investing in new systems, companies are increasingly relying on retrofitting: Pomini Tenova and Siemens demonstrate how existing roll grinding machines can be future-proofed with modern CNC technology, digitalization, and AI—efficiently, economically, and with clear productivity gains.

Pomini Tenova combines its process expertise and roll shop solutions with Siemens' CNC and automation technologies based on Sinumerik One. The focus is on retrofitting existing roll grinding machines—with the goal of bringing existing systems technologically up to date and significantly enhancing their performance. Through targeted modernization and upgrades, existing machines are transformed into future-proof systems. Users specifically benefit from:

Higher productivity through optimized processes
Improved processing quality
Extended machine lifespan
Reduced downtime
Better safeguarding of existing investments.

Retrofit Combines Mechanical Modernization with Digital Technologies

Digital solutions, predictive maintenance, and industrial AI extend classic retrofit concepts: they not only facilitate technical renewal but also lay the foundation for increasingly autonomous and data-driven operations. Pomini Tenova and Siemens are strengthening their long-standing partnership to further advance this approach. The goal is to support customers worldwide in the efficient and sustainable modernization of existing roll grinding machines.

CNC Platform Sinumerik One at the Center

The collaboration is based on over 40 years of experience and around 1,000 installed machines. Retrofit projects can thus be implemented in a structured and low-risk manner while safeguarding existing investments. Instead of completely replacing machines, central components are selectively modernized and technologically upgraded. Both partners contribute their strengths: Pomini Tenova provides process expertise as well as technologies for roll grinding, inspection, and roll shop automation. Siemens complements this with CNC controls, drive, and automation technology. The result is integrated solutions with current safety and cybersecurity standards.

At the center is the CNC platform Sinumerik One. It modernizes the machine control system while simultaneously providing access to advanced digitalization and automation possibilities. The retrofit approach combines mechanical modernization with digital technologies, thereby creating additional value:

Condition monitoring and diagnostics in real time
Predictive maintenance to prevent unplanned downtime
Continuous process optimization through Industrial AI
Gradual transition to autonomous operating models

The targeted retrofit of the CNC control system is the key to unlocking the full potential of existing machines. By combining automation, digitalization, and application expertise, we create a financially attractive alternative to new acquisitions.
