DIE HELITRONIC POWER DIAMOND 400 STUDER favoritCNC IN USE The top performer in terms of value for money stands for many years of precision. The favoritCNC with 650 (25.6”) or 1000 mm (39.4”) distance between centers for universal use is easy and quick to program thanks to StuderPictogramming. Due to various options such as a measuring system, balancing system, contact detection, and longitudinal positioning, the machine can be easily adapted to other grinding tasks.

LONGITUDINAL AND CROSS SLIDES GRANITAN® S103 MINERAL-CAST MACHINE BASE The material structure developed by STUDER on the basis of the company's own formula, which has proved its worth over many years, is produced in a plant using the most modern industrial techniques. The excellent damping properties of the machine base ensure that an outstanding surface quality is achieved in the ground workpieces. The service life of the grinding wheel is also increased, leading to reduced downtimes. Temporary temperature fluctuations are largely offset by the favorable thermal behavior of Granitan®. This results...

WHEELHEAD The wheelhead can be used for external and internal grinding; it can be equipped with an external grinding wheel (right) and an internal grinding spindle. Two variants are available: a fixed wheelhead, manually adjustable (0°/15°/30°), or optionally, a universal wheelhead with grinding wheel on the right and an internal grinding attachment (option) with manual swiveling using a 2.5° Hirth coupling. Grinding wheel size Diameter 500 mm (20"), width 63 (80F5) mm (2.4873.15" F5), bore 230 mm (8"). The drive power is max. 11.5 kW (15.4 hp). The cutting speed of maximum 50 m/s (9,840 sfpm)...

A universal workhead with MT5 fitting taper or a chuck workhead with MT4 fitting taper can be used. This makes both live spindle grinding and grinding between centers possible. The workpiece spindles are equipped with roller bearings, are low-maintenance, and offer excellent roundness accuracy of under 0.0004 mm (0.000,016”). The fine adjustment allows for cylindricity corrections in the micron range during live spindle operations. An air cushion lift-off facilitates movement of the workhead during setup and resetting. An easy-cutting grinding wheel is essential for cost-effective and high-quality...

PROGRAMMING The sophisticated mechanical engineering concept of the favoritCNC is complemented by a grinding software program developed in-house by STUDER and continuously optimized in cooperation with users. The grinding software offers: ■ StuderPictogramming: The operator sequences the individual grinding cycles and defines the grinding process. ■ Free programming of grinding and dressing cycles for optimization of the grinding process. ■ The StuderGRIND programming software enables programming on a PC or laptop. 2 StuderGRIND programming software UPGRADE OPTIONS MACHINE CONTROL AND OPERATION...
