EMO hosted the world premiere of the new Studer S23 universal cylindrical grinding machineFritz Studer AG left
EMO Hannover 2025 at the end of last month with a strong message — innovation in grinding technology remains central to maintaining customer competitiveness. CEO Sandro Bottazzo, reflecting on a successful week at the world’s leading manufacturing technology exhibition, said: “We are delighted that our innovations in grinding technology met with such great interest from international trade visitors.”
Among the highlights was the world premiere of the S23 universal cylindrical grinding machine. Compact yet powerful, the S23 is designed to bridge the gap between entry-level and the premium segments. It features Studer’s advanced C.O.R.E. hardware and software architecture, an automatic Ba-xis with 1deg Hirth serration accommodating up to three grinding tools, and a Granitan machine base engineered for optimal thermal and vibration stability.
Also drawing attention was the new generation of the favoritCNC. This popular entry-level model has been reimagined with a modern Fanuc 0i-TFP CNC control, an automatic operating door, and a loader interface to support automation. A resource-efficient belt spindle system and a redesigned machine base with increased X-guideway distance contribute to improved rigidity. The addition of ‘Conventional Mode’ allows operators to seamlessly switch between manual and CNC grinding, further enhancing versatility.
Commitment to precisionStuder’s commitment to precision was evident in its demonstration of an innovative axis system on the S31 machine, tailored for small to large workpieces. The extended W-axis enables automatic tailstock positioning, while the active R-axis, equipped with an in-process measuring system, scans complex geometries with ease. Notably, the system includes direct clamping force measurement, with real-time feedback displayed on the control screen — ensuring consistent and reproducible clamping conditions.
Another standout was the WireDress system for internal cylindrical grinding (pictured left). Based on wire electrical discharge machining, this non-contact dressing technology unlocks new geometries for diamond and CBN grinding wheels with sintered metal bonds. A newly developed internal grinding spindle allows current transmission at full grinding speed, marking a significant leap forward in capability.
Pascal Schärer, sales manager for Central Europe, said: “
EMO 2025 gave us the opportunity to demonstrate how Studer will continue to support our customers’ success. A clever mix of reliable and innovative grinding technology brings decisive advantages for competitiveness.”
