Abstract
A grinding worm (4) on a grinding spindle is driven in a rotating manner. On a rotatable plate (7), two workpiece spindles (6a, b) are positioned at a distance from one another and driven in a rotating manner. The one workpiece (5) is ground with the grinding worm (4), while on the other spindle (6b) a ground workpiece (8a) is exchanged for an unmachined part (8b) using a loader (10). Each spindle (6a, b) has a corresponding centering probe (9a, b). By means of the signal of the probe and a control mechanism, the newly clamped-on workpiece (8b) is centered before the rotating plate (7) is rotated into the position, in which this toothed gear (8b) can be brought into a mesh with the grinding worm (4). In such a way, the unproductive times can be largely reduced.
