The new S31 – The versatile machine for large tasks
The new S31 performs complex and varied grinding tasks precisely and reliably. It can be used to produce small to medium-sized workpieces with a distance between cen-ters of 400, 650, 1000 and 1600 mm and a center height of 175 mm in individual, small batch and high volume production. With a high-resolution B-axis of 0.00005° the swiv-eling wheelhead enables efficient external, internal and surface grinding in a single clamping.
The foundation of the universal cylindrical grinding machine is the machine bed made from solid Granitan® S103. This provides high dimensional stability thanks to its favorable thermal behavior, while the mineral casting largely equalizes short-term variations in temperature. STUDER has redesigned the machine base geometry and added an innovative base tem-perature control. This ensures quick and stable production. The fixing of the dressing device on the double T-slot of the longitudinal slide drastically reduces the complexity of setup and changeover. A further highlight: The S31 features StuderGuide® guideways with their damp-ing component in the direction of movement.
The S31 is based on the STUDER T-slide concept. It now has an extended X-axis stroke of 370 mm. This enables a large number of wheelhead variants, which can be precisely tai-lored to the customer's requirements. Customers can choose between the turret wheelhead with continuously variable B-axis or B-axis with 1° Hirth coupling. The turret wheelhead can be equipped with several grinding wheels. Thanks to the software for grinding wheel align-ment, STUDER Quick-Set, changeover times are reduced by up to 90 percent. The new S31 enables grinding of different diameters and cones with just one grinding wheel and without time-consuming intermediate dressing. This is made possible by the direct drive on the B-axis with a positioning scatter of <1".
Over a hundred years of grinding experience are invested in StuderWIN, which enables reli-able programming and efficient operation. StuderTechnology also automatically calculates the optimal grinding parameters in a matter of seconds, based on just a little information. This means good quality and a stable process at the first attempt. 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 optionally available with the Fanuc 31i-B for High Speed Machining (HSM). The PCU manual control unit enables setup of the machine close to the grinding process. Non-productive times can be reduced to a minimum with the electronic contact detection function. In addition, the standardized loader interface enables automation of the S31 .
