The new S31 - the versatile for big tasks

The new S31 handles complex and versatile grinding tasks precisely and reliably. It can produce small to large workpieces in single batch, small or large series and is available with centre distances of 400 mm (15,7") / 650 mm (25.6") / 1000 mm (40") / 1600 mm (63") and a centre height of 175 mm (6.9"). With a high-resolution B-axis of 0.00005 °, the swiveling wheelhead makes efficient external, internal and face grinding possible in one setup.

The basis for the universal cylindrical grinding machine is the machine bed made of solid Granitan® S103. Thanks to its favorable thermal behavior this offers a high degree of dimensional stability, short-term temperature fluctuations are largely compensated for by the mineral casting. STUDER has redesigned the machine base geometry and supplemented it with an innovative machine base temperature control. This ensures a fast and stable production. The mounting of the dressing unit on the double T-slot of the longitudinal slide massively reduces the time needed for setup or changeover of the machine. Another highlight: The StuderGuide® guideways of the S31 have an additional convincing argument with its damping component in the direction of movement.

A wide range of wheelhead configurations.

The S31 is based on the STUDER T-Slide concept. It now has an extended X axis stroke of 370 mm (14.5") This allows for a variety of wheelhead variants. Configured exactly to the needs of the customer. You can choose between the turret wheelhead with an infinite B-Axis or a B-axis with 1° Hirth coupling. The turret wheelhead can be equipped with several grinding wheels. Thanks to the grinding wheel set-up software, STUDER Quick Set, the changeover times are reduced by up to 90 percent. With the new S31, you grind different diameters and any taper with just one grinding wheel and without time-consuming intermediate wheel dressing. This is made possible by the direct drive on the B-axis with a positioning accuracy of < 1 arcsec.

Convincing software

More than a hundred years of grinding experience is integrated in StuderWIN, which enables safe programming and efficient use. StuderTechnology requires just a few parameters to automatically calculate precise grinding parameters in just seconds. This means good quality and a stable process right from the start. The optional integrated modules such as StuderForm, StuderThread or StuderContourBasic extend the functionality of the machine.

The S31 is equipped with a Fanuc 0i-TF and is available with the Fanuc 31i-B for high-speed machining (HSM) as an option. The hand-control device PCU makes it possible to set up the machine close to the grinding process. With electronic contact detection, downtimes can be reduced to a minimum. With the standardized loader interface, the S31 can also be automated.
