Studer S120 CNC production internal cylindrical grinding machine

S120 - The quick and nimble for small bores

The Studer S120 is a compact CNC production internal grinding machine with a cross-slide design for up to 2 internal grinding spindles. The machine enables productive machining of components with an external diameter of up to 50mm and is suitable for small series production as well as for use in production systems. The extensive range of internal grinding spindles and special internal grinding modules provides the ideal basis for modular configurability.

It can be automated to give around the clock production and the proven pictogramming allows even less experienced users to quickly optimise the potential of this machine.
