USED STUDER S120

The S120 is a compact internal grinding machine with a cross-slide design
for up to two internal grinding spindles. The machine enables productive
machining of components with an external diameter of up to 50 mm and
is suitable for both small series operations as well as for use in production
systems. The wide range of internal grinding spindles and special internal
grinding assemblies provides the ideal basis for modular configurability
