STUDER-External cylindrical grinding machines, also with internal grinding device

For large serie production STUDER supplies tailored solutions with optimized grinding cycles and high machine availability.

Available models


The S11 is a production machine, which is precisely tailored to the desired process. Highly dynamic axis drives, high-quality STUDER guideway systems, short reaction times and optimized traverses form the basis of the S11. The high-speed grinding option (HSG) contributes to increasing productivity with its peripheral speed of up to 140 m/s.

With a mounting area of less than 1.8 m2, it is extremely compact and will fit in any workshop.

Precision is the result of perfect interaction between a large number of different factors. The basis is the Granitan® S103 machine base with its excellent damping characteristics and favorable thermal behavior. The modules are ideally suited to each other and produced with customary STUDER precision.
