Abstract
A grinding wheel which is formed from super hard abrasive grains is trued by traverse-feeding a truing tool a plurality of times (n). Among the (n) traverse feeds of the truing tool, every traverse feed except for the final (i.e., from the first to the (n-l)th traverse feed) is carried out with an infeed which is set at a relatively small value in order to remove any deflection of the grinding wheel. In the final traverse feed, the infeed of the truing tool is set at a relatively large value in order to form an excellent cutting edge on the grinding wheel. Accordingly, any deflection of the grinding wheel is removed by a plurality of traverse feeds of the truing tool carried out with a relatively small infeed, and a cutting face having an excellent cutting ability is formed on the grinding wheel by the final traverse feed carried out with a relatively large infeed.
