The S22 is a production platform. It focuses on medium-sized customer workpieces in large-scale production. The aim is to be able to machine any workpiece on the S22 with a wide range of technologies: conventional cylindrical grinding in the production environment, form and thread grinding, high speed grinding (HSG) with cutting speeds between 80 and 140 m/s, or heavy-duty applications with 160mm wide grinding wheels.
