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 on the basis of the company’s own formula, is produced in a facility using the most modern industrial techniques. The excellent damping properties of the machine base ensure that outstanding surface quality is achieved on 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...

WORKHEAD All requirements are covered by wide range of workheads. They are all solidly built in the superior STUDER quality and achieve roundness accuracy of 0.0004 mm (0.000,016”) (optionally even 0.0002 mm (0.000,008”) in live spindle grinding. Simple cylindricity correction contributes toward perfect live spindle grinding results. Customer-specific workpiece clamping and carrier systems can be easily used. High roundness accuracy Universal workhead MT4 For external grinding with fixed centers or live spindle grinding; especially suitable for smaller workpieces. The spindle is blocked for...

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 taper corrections in the range below 1 μm (0.000,040”) when grinding between centers. DRESSING In order to guarantee optimum thermal stability, the tailstock is flooded with cooling lubricant, as are the barrel and the...
