If you want to have state-of-the-art technology for your internal grinding applications too, then take a few minutes – for the S131/S141/S151. Whether flange parts or spindles up to 1 300 mm (51.1") in length, they can master any challenge. The incomparable STUDER precision is based on the Granitan® machine bed and the StuderGuide® guideway system. During development the emphasis was placed on the machine ergonomics in relation to grinding, setup and m

Hardware • StuderGuide® guide system with linear drive • Very simple operation and programming thanks to StuderWIN • Grinding spindle turret with up to four grinding spindles • Short setup and resetting times e.g. with STUDER Quick-Set • Automatically swiveling workpiece table • Standardized interfaces for loader and peripheral devices • C-axis for workhead spindle for form and thread grinding • Full enclosure with two sliding doors • Granitan® S103 mineral casting machine base

The S131 is the most compact machine in this series. The swing diameter above the workpiece table is 250 mm, and the maximum workpiece length (including clamping device) is 300 mm. The S131 therefore shows its strength with flange parts and smaller workpieces of all types. The S131    141    151 are CNC universal internal cylindrical grinding ma/S /S chines of the latest generation. They have a host of sophisticated technical features such as the revolutionary StuderGuide® guideway system, highprecision axis drives with linear motors, extremely fast direct drive of the grinding spindle...
