Available from United Grinding, Studer’s S11 cylindrical grinding machine is designed for the production of micro components such as injection nozzles for diesels. The compact machine is energy-efficient and said to provide increased productivity and output over its predecessor, the S36, while occupying the same amount of floor space with a footprint of 1.8 m2.
The grinder accommodates workpieces as long as 200 mm, ranging to 50 mm in diameter and weighing as much as 3 kg. The center height is 125 mm. A 500-mm-diameter grinding wheel can be rotary-dressed for increased productivity; the wheelhead can be set at 0 or 20 degrees. The motor grinding spindle is water-cooled and fitted with high-precision roller bearings.
The machine has a stroke of 210 mm in the X and Z axes, and is capable of speeds ranging from 0.001/1000 to 30,000 mm/min. The axes have a resolution of 0.00001 mm, and positioning is accomplished via ballscrews. The Granitan machine bed features high-precision linear guides with cross-slides for the X and Z axes. According to the company, the use of pneumatics and electrics rather than hydraulics provides increased thermal stability. A three-stage door in the front is designed for accessibility for manual or automatic workpiece handling. The grinder also is equipped with the StuderWINfocus grinding software package, a touchscreen and a graphic user interface.
