The S23 universal cylindrical grinding machine from Fritz Studer AG combines high precision, flexibility and modern grinding technology in a compact design. According to the company, the machine was unveiled to the global public at EMO Hannover in September 2025.
“Thanks to its high-quality features, precision, and flexibility, the S23 complements our portfolio in the entry-level and premium segments,” said Sandro Bottazzo, CEO of Fritz Studer AG. The CNC machine brings together the 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 a machine base made of Granitan®, which the company highlights for its thermal and vibration characteristics.
The arrangement of the wheelhead allows a wide range of grinding tools to be used in a single clamping, which increases efficiency, particularly with geometrically complex workpieces. Contact detection, semi-automatic balancing of the external grinding wheel and an optional in-process measuring system support consistent part quality.
From tool and die to medical technology
The S23 is designed to grind small to medium-sized workpieces, including complex geometries, in both single-part and series production. “The S23 is ideal for production in the tool and die, automotive and supplier, aerospace, and in the medical technology industries,” said STUDER Sales Manager Rolf Grossenbacher. Configuration options include a C-axis for thread and out-of-round grinding and an optional swiveling table; customer-specific adaptations are also possible.
Operation runs through the C.O.R.E. touch panel and StuderWIN software, which the company says allows operators to achieve reliable results after a short introduction. The QuickSet function keeps set-up and changeover times short, while standardized loader interfaces for easyLoad and insertLoad enable economical automation.
