STUDER, which presented the S23 universal cylindrical grinding machine at EMO Hannover 2025, offers high precision, great flexibility and modern grinding technology in a compact design with an attractive price-performance ratio.
Offering a reliable, state-of-the-art grinding machine in a compact design, the S23 brings together features such as the modern C.O.R.E. hardware and software architecture, an automatic B-axis with a 1° Hirth coupling for up to three grinding tools, motor spindles with frequency control or belt drives, and a machine bed made of Granitan® with outstanding thermal and vibration properties. “Thanks to its high-quality features, precision and flexibility, the S23 rounds off our portfolio in the entry-level and premium segments,” explains Sandro Bottazzo, CEO of Fritz Studer AG.
Users also benefit from the innovative design that STUDER has developed for the S23. The layout of the wheelhead, which provides excellent versatility for grinding tools in a single clamping, increases productivity, particularly for geometrically complex workpieces. State-of-the-art grinding technology such as contact detection, semi-automatic balancing of the external grinding wheel and an optional in-process measuring system ensures high-quality results.
The optimum solution for a wide range of users
With these features, the S23 becomes an ideal solution for a wide range of users, grinding small and medium-sized workpieces with complex geometries in single-part and series production with high precision and process reliability. “The S23 is ideal for production in industries such as tool and mould making, automotive and suppliers, aerospace and medical technology,” says Rolf Grossenbacher, Head of Sales at STUDER. Users also have numerous configuration options to adapt the machine to their own production requirements. These include a C-axis for thread and non-circular grinding and an optional rotary table, while customer-specific adaptations are also possible.
Thanks to the latest digital technology and sensor technology, the machine offers simple and intuitive operation. After a short introduction, operators can achieve reliable, high-quality results using the C.O.R.E. touch panel and the StuderWIN software. The practical QuickSet function also keeps set-up and changeover times to a minimum. Users who want to automate their production can do so efficiently and economically thanks to standardised loader interfaces for easyLoad and insertLoad. In addition to these features, users of course benefit from STUDER’s worldwide expert customer service and the experience of a traditional Swiss company with a history of more than 111 years. “This makes the S23 a high-precision universal cylindrical grinding machine with an excellent price-performance ratio,” summarises CEO Bottazzo.
