productivity with its peripheral speed of up to 140 m/s.
With a floorspace requirement 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 ofdifferent factors. The basis is the Granitan® S103 machine base with its
excellent damping characteristics and favorable thermal behavior. Themodules are ideally suited to each other and produced with customary
STUDER precision.

The material structure developed by STUDER, which has proved its superb
efficiency over many years, is produced in the company’s own plant using
the most modern industrial techniques.
•	The excellent dampening behavior of the machine base ensures
outstanding surface quality of the ground workpieces. The service
life of the grinding wheel is also increased, leading to reduced
downtimes.
•	Temporary temperature fluctuations are extensively compensatedfor by the favorable thermal behavior of Granitan®, resulting inhigh dimensional accuracy at all times. This provides high stability
throughout the day.

Cross-slides
12• High geometric traverse precision• Effective covering of the guideways

The X and Z-axis are designed as a cross slide,and the workpiece table is bolted permanently tothe machine. This cross-slide system has been
proven for years in STUDER production cylindrical
grinding machines. High-precision guideway systems and dynamic axis drives in conjunction withrobust design guarantee high process reliability
in production.
The cross slide forms a self-contained unit. Bothaxes have linear guideways mounted on roller
bearings.

12• High roundness accuracy• Low-maintenanceWith its high-precision roller bearings the workhead is used for grinding
between fixed centres and for live spindle grinding. The powerful workhead spindle has a MT4 fitting taper.
The machine can also be fitted with a specially designed chuck workhead
for chuck applications. The workheads are mounted on roller bearings,
are low-maintenance and possess an excellent roundness accuracy of
below 0.0004 mm (optionally 0.0002 mm) during live spindle grinding
operations.
The airlift simplifies adjustment when setting up or resetting the workhead. The fine adjustment enables taper corrections in the μm-range
during live spindle grinding.

3An easy-cutting grinding wheel is essential for cost- effective, high-quality
grinding. In order to create a flexible and optimal dressing process that coordinates with the properties of the workpiece, tool and materials, STUDER
provides a large selection of dressing units. The grinding wheel profileand dressing parameters are easily defined via macros. Another STUDER
speciality is the grinding wheel reference points (T-numbers). This enables
programming with normal dimensions, which considerably facilitates thedevelopment of grinding programs.
A software package is available to fine tune the dressing process andincludes additional dressing functions.

The S11 features a Fanuc 0i-TF. The clear andergonomic arrangement of the control elements
guarantees efficient operation.
The projective-capacitive touchscreen, withcontinuous glass plate over the entire panel,is resistant to scratches and dirt and can evenbe operated with gloves without problem. An
important role is played by the manual control
unit, which facilitates setup close to the grinding
process.
The control cabinet is installed behind themachine, flush or angled according tocustomer requirement. The layout of the elementscomplies with the relevant safety norms and isEMC-tested.

S11Automation
12• Automated production processes• Integrated quality control• Standardized loading interfaces

The S11 is designed as a production grinding system. It is available intwo casing variants. With the rounded casing, it is particularly suitable
for manual loading or in combination with small handling systems. A newcasing type is optimized for vertical loading with a hatch. It is therefore
perfect for an interlinked production system, in which the machines areloaded and unloaded via portal cranes. Both designs stand out with their
excellent accessibility and ergonomic features.
The corresponding peripherals ensure seamless integration into the respective production process. The handling systems used communicate
with the machine via the standardized loader interface and enable evencomplex handling tasks to be solved.
Comprehensive quality control is possible during the grinding process.
Optimum accessibility is guaranteed at all times by service doors on theleft and right. Pneumatic components are integrated into the machine bed
so that they are clear and easily accessible.
