The surface The generous guide spacings provide the basis for a stable and robust structure prevents the slides from swimming up and also eliminates the design of cross slide and wheelhead....

• Configurable according to client’s requirements • High performance • Cutting speed up to 50 m /s (HSG 140 m / s) The S22 platform has many different wheelhead variants. The machine can be optimally configured for any application. A swiveling unit with swiveling angle ±9 deg for the right and the left wheel, is available for the 0 deg machine model. A turret wheelhead with wheel left / left resp. right / left rounds off the program. 1 Wheelhead 2 Automatic A-axis 3 Examples for wheelhead configurations Automatic A-axis STUDER offers an automatically swiveling A-axis on the S22 for...

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 or ISO50 fitting taper. • High roundness accuracy • Low-maintenance 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. C-axis for form and thread grinding 3 Complete machining also entails form and thread grinding operations to an ever increasing extent. These processes are made possible by the position and...

Tailstock, synchronous tailstock 1 • Taper corrections • Thermal stabilization via overflow capacity • Synchronous tailstock The rigid tailstock with generously dimensioned barrel is extremely stable and guarantees optimum grinding conditions for grinding between centres. The barrel slides in effectively covered floating bearings. The centre pressure can be adjusted simply and sensitively. The tailstock also has an air lift for quick and easy adjustment. In order to guarantee optimal thermal stability, the tailstock is flushed with coolant and both barrel and diamond holder are flooded. 1...

A sharp grinding wheel is essential for costeffective, 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 the...
