Abstract
A grinder with a deflection sensor for controlling the grinding work conditions based on an amount of deflection of a grinding shaft occurring in the normal direction relative to the grinding shaft which is detected by measuring inductance with the deflection sensor. Based on a deflection of the grinding shaft detected during grinding work, the feed of the grinder is controlled, and the sharpness of the grinder is determined based on changes of the detected deflection amount during spark-out, moreover an error in the signal from the deflection detector caused by a thermal change can be compensated, whereby grinding work is carried out under an optimum condition, and the grinding accuracy and efficiency are improved.
