USER INTERFACE StuderWIN The user interface StuderWIN creates a stable programming environment and contributes to efficient use of the machine. The possibility of fully integrating the in-process gauging and sensor technology for process control as well as contact detection and automatic balancing systems in the operator interface enables standardized programming of the different systems. The software of an optional loading system is also integrated. The drive elements are optimally matched to the control system. The sophisticated mechanical engineering concept of the S41 is completed by a grinding...

GRANITAN® S103 MINERAL CASTING MACHINE BED STUDERGUIDE® IN LONGITUDINAL AND CROSS SLIDES 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 compensated by the favorable thermal behavior of Granitan®. This provides high...

TURRET WHEELHEAD The most important component for complete machining is the wheelhead with integrated B-axis. It swivels automatically, and enables the use of up to four grinding wheels. This means that workpieces can be completely machined in the same clamping – with minimal auxiliary times combined with superior precision. This B axis has a direct drive, which positions very quickly and precisely. The high-resolution direct measuring system guarantees a repetition accuracy of the high-precision B-axis < 1”. Automatic A-axis STUDER offers an automatically swiveling A-axis on the S41 for efficient,...

WHEELHEAD VARIANTS Combinations of up to four external or internal grinding spindles result in more than 30 basic variants. Internal grinding spindles with 6 000 rpm to 120 000 rpm can be used. Automatic balancing systems and frequency converters for the individual external grinding spindles enable even better coordination of the wheelhead variants with the grinding process. A vertical spindle for grinding splines can also be mounted on the wheelhead as a special solution. INTERNAL GRINDING

WORKHEAD A wide range of workheads covers all requirements. These are all sturdily built in the highest STUDER quality and achieve a roundness accuracy during live grinding of 0.0004 mm and optionally even 0.0002 mm. Easy cylindricity correction helps to achieve perfect results during live grinding. Customer-specific workpiece clamping and driving systems can be easily used. High roundness accuracy Low-maintenance Air cushion Universal workhead For external grinding with a fixed center or for live grinding. The spindle is locked for grinding between fixed centers. C-axis applications are possible...

TAILSTOCK The generously dimensioned barrel, designed for the deployment of Morse 4 taper centres, glides in the tailstock housing. The centre pressure can be adjusted with the delicate precision required for grinding high-precision workpieces. The tailstock can be equipped with a hydraulically actuated barrel retraction for workpiece changeover. The fine adjustment enables cylindricity corrections in the range below 1 μm DRESSING when grinding between centres. An air cushion lift-off facilitates simple movement during setup and resetting. A cooling lubricant is passed through the tailstock and...

AUTOMATION Several loading systems are available for the S41. From the cost-effective easyLoad, which is operated via the machine control, to the easyLoad NC with its own control unit, through to special solutions which can be precisely adapted to the machine application and machining processes, thanks to their modular design. A Datamatrix code reader or a laser marking system ensures that each workpiece receives its own identity, and process data can be traced at any time. The appropriate peripherals ensure seamless integration into the respective production process. Project-specific components...
