Abstract
Short and/or rod-shaped workpieces are completely machined by grinding two parallel end faces and the longitudinal sides of the workpiece with very short cycle times. The grinding machine includes two grinding spindles that are arranged in a tandem arrangement with parallel rotational axes on a shared grinding headstock and that are jointly moved in the X direction. In cooperation with a special holding and transport device for the workpieces, two workpieces are each ground, at least partly concurrently, the end faces of the one workpiece being ground in one machining position and the final non-circular grinding of the exterior contour of a second workpiece occurring in a second machining station, the end faces of the second workpiece having already been ground.
