ABSTRACT:
The invention relates to a method for calibrating a grinding machine for sharpening bar blades by grinding at least two flanks and a top surface (K) of the bar blades, involving the following steps: producing a calibrating blade by sharpening a bar blade according to predetermined dimensions; measuring the dimensions of the calibrating blade, and; calibrating the machine with the aid of at least the measurement result. In order to produce a calibrating blade, the bar blade is, in at least two steps, ground on the flanks and on the top surface (K) in a complete calibrating grinding. The inventive method is advantageous in that the calibrating blade is ground under the same conditions as a production blade so that process-related influences, in particular, displacements associated with the grinding forces, can also be taken into consideration.
