The service life of the grinding wheel is also increased, leading to reduced downtimes. • Temporary temperature...

• 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 to the 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 with robust design guarantee high process reliability in production. The cross slide forms a self-contained unit. Both axes have linear guideways mounted on roller bearings. 1 Cross-slides 2 Workpiece table The axes are effectively...

• High roundness accuracy • Low-maintenance With 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...

An 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 profile and 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 the development of grinding programs. A software package is available to fine tune...

• Compact manual control unit • EMC-tested control cabinet • Ergonomically designed • Operating elements The S11 features a Fanuc 0i-TF. The clear and ergonomic arrangement of the control elements guarantees efficient operation. The projective-capacitive touchscreen, with continuous glass plate over the entire panel, is resistant to scratches and dirt and can even be 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 the machine, flush or angled according...
