Abstract
The invention relates to a grinding center for the simultaneous grinding of multiple main bearings and rod bearings and/or central sections of crankshafts (). Two rod bearing grinding spindles (), wherein the first can be displaced only in the Z direction and the second can be minimally displaced only in the X direction, are mounted on a common rod bearing crosslide (). In the final phase of the grinding, a correction of dimension deviation between the two machined rod bearings is carried out via a separate control of the second rod bearing grinding spindle (), as a dimension or roundness correction. The deviations are detected by measuring devices.
