About the Studer S31 Grinder
The Studer S31 is a high-precision CNC cylindrical grinding machine engineered by Fritz Studer AG, designed to deliver versatility, accuracy, and reliability for a broad range of grinding applications. From single prototype parts to high-volume production runs, the S31 stands out as a flexible solution for manufacturers who demand performance and quality from a universal grinding platform. Built to handle external, internal, and face grinding, the S31 accommodates workpieces of various sizes thanks to selectable distances between centers of 400 mm, 650 mm, 1000 mm, and 1600 mm, and a center height of 175 mm. The machine can handle parts weighing up to 150 kg (330 lbs), making it suitable for industries ranging from automotive to aerospace and heavy machinery. At the heart of this listed machine is a FANUC 21i-TB CNC control system paired with Studer grinding capability, supported by a Granitan S103 mineral casting base known for thermal stability and vibration damping. This construction helps maintain high precision even under changing temperature conditions, minimizing thermal distortion that could impact tolerances. Optional integrated modules and accessories can extend the machine’s capabilities for specialized grinding tasks, while the listed rotary disc dresser, coolant system, and length positioning probe make this S31 a strong fit for shops needing flexible cylindrical grinding performance.
