C.O.R.E. – CUSTOMER ORIENTED REVOLUTION C.O.R.E. PANEL – THE FUTURE OF OPERATION 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...

USER INTERFACE StuderWIN The user interface StuderWIN creates a stable programming environment and contributes to the efficient use of the machine. The possibility of fully integrating the measuring system and sensor technology for process control, contact detection and 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 software options for the grinding technology calculations, optimized dressing as well as the...

GRANITAN® S103 MINERAL CASTING MACHINE BASE STUDERGUIDE® IN LONGITUDINAL AND CROSS SLIDES The material structure developed by STUDER, which has proved its worth over many years based on the company’s formula, is produced in a plant using the most modern industrial techniques. The excellent damping properties of the machine base ensure outstanding surface quality in the ground workpieces. The life of the grinding wheel increases, leading to reduced non-productive times. Temporary temperature fluctuations are extensively compensated by the favorable thermal behavior of Granitan®, resulting in...

WHEELHEAD Reduce set-up and resetting costs? It is possible with this machine, especially in single-part or small-batch production, by the wheelhead with several grinding wheels and rapid setup with QuickSet. Boost efficiency with complete machining in a single clamping. The S33 handles internal, external, and face grinding with ease. Complete machining Motor spindles High cutting speed of up to 63 m/s (12,400 sfpm) 3 tools (2x external, 1x internal or 1x external, The swiveling wheelhead is equipped with water-cooled, roller-based, and maintenance-free motor spindles with infinitely...

WORKHEAD All requirements are covered by the wide range of workheads. They are all solidly built to the superior STUDER quality and achieve roundness accuracy of 0.0004 mm (0.000,016”) (optionally even 0.0002 mm (0.000,008”) with live spindle grinding. The simple cylindricity correction contributes towards perfect live spindle grinding results. Customer-specific workpiece clamping and driving systems can be easily used. High roundness accuracy Universal workhead For external grinding with fixed centers or for live spindle grinding. The spindle is blocked for grinding between fixed centers....

TAILSTOCK The generously dimensioned barrel, designed for the use of morse 3 or 4 taper centers, glides in the tailstock housing. The center 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 change-over. The fine adjustment enables cylindricity corrections in the range below DRESSING 1µm (0.000,040”) when grinding between centers. An air cushion liftoff facilitates simple movement during setup and resetting. Coolant flows through the tailstock and...

CUSTOMER CARE – WE ARE HERE FOR YOU AUTOMATION Several loading systems are available for the S33. From the cost-effective easyLoad, which is operated via the machine control, to the uniLoad with its own control unit, through to special solutions that can be precisely adapted to the machine application and machining processes thanks to their modular design. The appropriate peripherals ensure seamless integration into the production process. Using a data matrix code reader or a laser labeling machine, each workpiece is assigned its own identity; process data can be traced at all times. The...
