Abstract
A grinding center for the simultaneous grinding of a plurality of main and rod bearings and/or central and end-side sections of crankshafts includes first and second stations. Two main bearing grinding spindles, of which the first is movable only in the Z-direction and the second only insignificantly movable in the X-direction, are mounted on a common rod bearing-compound slide. In the final phase of grinding, a correction of variations in size between the two processed rod bearings occurs via a separated drive of the second rod bearing-grinding spindle in accordance with a size or roundness correction. The variations are detected by measuring devices. An inclined profiled grinding wheel is provided for the grinding of the end sections.
