GRANITAN® S103 MINERAL-CAST MACHINE BASE STUDERGUIDE® IN LONGITUDINAL AND CROSS AXIS The material structure developed by STUDER on the basis of the company’s own formula, which has proven 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 extensively compensated by the favorable thermal behavior...

WHEELHEAD The S121 can be configured with either a fixed spindle or a spindle turret with two spindles. The turret swivels hydraulically 180° to a stop. One spindle can be equipped with an external grinding wheel. 1 fixed spindle or 2 spindles on a turret Wide range of grinding spindles External grinding wheel can be changed with just a few simple steps 1 Wheelhead 2 Wheelhead variants 3 Internal grinding spindle with measuring probe in background

WORKHEAD WE ARE HERE FOR YOU! The workhead is mounted on a movable workpiece table. It delivers 3 kW (4 hp) of drive power and supports up to 300 Nm (221 ft-lb) of load during live spindle grinding. It includes manual cylindricity correction. The high-resolution C axis with direct measuring system is ideal for form and thread grinding. The machine's design ensures optimal accessibility for the operator, whether for changing workpieces, dressing, or changing the grinding wheel. ■ Adjustable workpiece spindle ■ Cylindricity correction Our products are designed to meet customer demands for as long...
