Cylindrical Grinder Designed for Micro Components

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.
