Claim:
1. A method for grinding bevel gears comprising: a) fastening a first grinding tool on a tool spindle of a grinding machine, b) fastening a first workpiece on a workpiece spindle of the grinding machine, c) performing a CNC-controlled first single-indexing grinding procedure using the first grinding tool, wherein all first tooth flanks of the first workpiece are machined by grinding step-by-step during said first single-indexing grinding procedure, d) separating the first workpiece from the workpiece spindle, e) at a later point in time, re-chucking the first workpiece on the workpiece spindle of the grinding machine, which carries a second grinding tool on the tool spindle, f) performing a measurement procedure using a sensor of the grinding machine to obtain sampling values at least for a part of the first tooth flanks, and determining a concentricity error of the first workpiece After said re-chucking, g) determining concentricity correction dimensions using a computer, and h) performing a CNC-controlled second single-indexing grinding procedure using the second grinding tool, wherein all second tooth flanks of the first workpiece are machined by grinding step-by-step during said second single-indexing grinding procedure, and executing machining movements during the second single-indexing grinding procedure based on said concentricity correction dimensions.
