Abstract
A device for detecting grinding wheel life is provided including a truing tool wear detection device for detecting a total wear amount of a truing tool after every truing operation and an arithmetic and judgement circuit arrangement. The circuit arrangement compensates for the total wear amount by a theoretic in-feed amount through which the truing tool has to have been in-fed from its original position when the grinding wheel is worn down to a predetermined limit. Further, the circuit arrangement calculates an actual in-feed amount of the truing tool and by comparing the actual in-feed amount with the compensated theoretical in-feed amount, judges whether or not the grinding wheel has been worn down to a predetermined limit.
