STUDER has introduced the S23, a universal cylindrical grinding machine designed to deliver high precision and flexibility within a compact footprint.
The machine combines modern grinding technology with a space-efficient design, offering manufacturers a solution for precision grinding applications at an attractive price-performance ratio.
The S23 was unveiled to the global manufacturing industry at the EMO trade fair in Hanover, Germany, in September 2025. Its compact design and versatile capabilities position it as an option for manufacturers seeking advanced cylindrical grinding technology while optimising shopfloor space.
“Thanks to its high-quality features, precision, and flexibility, the S23 complements our portfolio in the entry-level and premium segments,” explains Sandro Bottazzo, CEO of Fritz Studer AG. With a compact footprint, the CNC universal cylindrical grinding machine offers state-of-the-art, reliable grinding technology. These include the modern C.O.R.E. hardware and software architecture, an automatic B-axis with 1° Hirth coupling for up to three grinding tools, frequency- controlled motor spindles or belt drives, and the machine base made of Granitan® with its outstanding thermal and vibration characteristics.

Customers also benefit from the innovative design that STUDER has developed for the S23. The arrangement of the wheelhead allows great versatility for the grinding tools in a single clamping, increasing efficiency, especially with geometrically complex workpieces. State-of- the-art grinding technology such as contact detection, semi-automatic balancing of the external grinding wheel and the optional in-process measuring system ensure high-quality results.
Optimal Solution for a Wide Range of Customers
This makes the S23 the ideal solution for a wide range of customers. With high accuracy and process reliability, it grinds small to medium-sized workpieces, even with complex geometries, in single and series production. “The S23 is ideal for production in the tool and die, automotive and supplier, aerospace, and in the medical technology industries,” explains STUDER Sales Manager Rolf Grossenbacher. In addition, customers have numerous configuration options for adapting the machine to their individual production requirements. These include a C-axis for thread and out-of-round grinding and an optional swiveling table. Customer-specific adaptations are also possible.
Thanks to state-of-the-art digital technology and sensor technology, operation is simple and intuitive. After just a short introduction, employees can achieve reliable, high-quality results using the C.O.R.E. touch panel and StuderWIN software. Set-up and changeover times are also minimal, thanks to the practical QuickSet function. Customers who want to automate their production can do so efficiently and economically thanks to the standardized loader interfaces for easyLoad and insertLoad. And, of course, they benefit from STUDER’s world-wide competent customer care and the experience of a traditional Swiss company with over 111 years of history. “This makes the S23 a high-precision universal cylindrical grinding machine with an excellent price-performance ratio,” summarizes CEO Bottazzo.
