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 centres of 400, 650, 1 000 and 1 600mm and a centre height of 175mm in individual, small batch and high-volume production. With a high-resolution B-axis of 0.00005° the swivelling 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 favourable thermal behaviour, while the mineral casting largely equalises short-term variations in temperature. Studer has redesigned the machine base geometry and added an innovative base temperature 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 damping component in the direction of movement.
Very wide range of wheelhead variants
The S31 is based on the Studer T-slide concept. It now has an extended X-axis stroke of 370mm. This enables a large number of wheelhead variants, which can be precisely tailored 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 alignment, Studer Quick-Set, changeover times are reduced by up to 90 per cent. 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 reliable 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 standardised loader interface enables automation of the S31.
The S31 has distances between centres of 400mm, 650mm, 1 000mm and 1600mm, a centre height of 175mm and maximum workpiece weight 150 kilograms.
