YOUR BENEFIT Short processing time thanks to complete machining Highest precision thanks to perfect interaction of hardware and software Intuitive, user-oriented and efficient operation Access to important information directly at the panel (e.g. production progress, job details, etc.) Reduced programming effort during data exchange between C.O.R.E. machines Use of UNITED GRINDING Digital Solutions™ products directly on the machine Fast support thanks to direct interaction with our Customer Care team on the machine Ecological thanks to targeted measures for lower energy consumption Ergonomic...

C.O.R.E. – CUSTOMER ORIENTED REVOLUTION C.O.R.E. helps us make your production fit for the digital future. It’s based on a new operating system, C.O.R.E. OS that equips the machine with intelligence. Thanks to the uniform C.O.R.E. software architecture, exchanging data between UNITED GRINDING machines is easy. The integrated umati API can be used to communicate with third-party systems as well. It also offers access to UNITED GRINDING Digital Solutions™ products directly on the machine. C.O.R.E. not only establishes the technical foundation for this and other IoT and data applications, it...

C.O.R.E. PANEL – THE FUTURE OF OPERATION Intuitive Thanks to intuitive design with self-explanatory icons, navigation through the machine menu and process steps is quick and easy. Instead of buttons, the user is presented with a modern and clearly arranged multi-touch display. User-friendly Each user configures their own user interface individually. This is called up automatically with the RFID chip after logging in. When the user leaves the machine, the panel switches to «Dark Factory Mode.» Production progress and the machine state are also clearly visible from a INDUSTRIAL MULTI-TOUCH...

USER INTERFACE StuderWIN The user interface StuderWIN creates a stable programming environ- he software options for the grinding technology calculations, optiT ment and contributes to efficient use of the machine. The possibility of mized dressing as well as the Contour-, Thread- and Formgrinding fully integrating the in-process gauging and sensor technology for procycles increase the functionality of the machine. cess control as well as contact detection and automatic balancing systems in the operator interface enables standardized programming of More than 100 years of know-how the...

Integrated Tools Thanks to the many different extension packages, the functionality of STUDER grinding machines can be considerably enhanced. STUDER offers the necessary software packages in the form of Integrated Tools. tuderDress Integrated reduces the profiling time of a grinding S wheel by up to 80%. tuderThread Integrated together with the Studer thread grinding S cycles, offers the full functionality that is otherwise only possible on a special thread grinding machine. tuderContourBasic Integrated is for anyone who wants to trace S any geometry contour with the grinding wheel easily,...

GRANITAN® S103 MINERAL CASTING MACHINE BED 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 stability throughout the day. The...

STUDERGUIDE® IN LONGITUDINAL AND CROSS SLIDES The longitudinal and cross slides are manufactured from high-quality gray cast iron and have highly precise, ground guideways. The slides rest completely on the guideways of the machine bed through the entire traversing range. This provides the cornerstone for the excellent straightness of 0.003 mm over 950 mm measured length. The top of the longitudinal slide has a surface that is ground over its entire length and acts as a support for the workhead, the tailstock, as well as accessories and devices. A setup scale, recessed in the table, makes...

WHEELHEAD Reduce set-up and resetting costs? This is possible with this machine, especially in single-part or small-batch production. This is made possible by the turret wheelhead with several grinding wheels and QuickSet for rapid set-up. Boost efficiency with complete machining in a single clamping. The S31 handles internal, external, and face grinding with ease. C omplete machining M otor spindles H igh cutting speed of up to 63 m/s (12398 sfpm) 3 tools (2× external, 1× internal or 1× external, 2× internal) The direct drive on the B axis with high-resolution direct measuring system...

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. igh 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...
