Claims

[Scope of Claim for Utility Model Registration] (1) In a dressing device for a grinding machine having a grinding wheel head that supports a rotatable grinding wheel shaft with a grinding wheel attached to its tip, a grinding wheel diameter detection means that is arranged in the direction of the grinding wheel and moves relative to the grinding wheel head in the axial direction of the grinding wheel shaft to detect the diameter of the grinding wheel along the axial direction of the grinding wheel shaft; and a maximum value and a minimum value of the grinding wheel diameter. The uneven wear amount calculation means detects and calculates the difference to calculate the uneven wear amount, and the uneven wear amount calculation means compares the uneven wear amount calculated by the uneven wear amount calculation means with a limit uneven wear amount stored in advance. 1. A dressing device for a grinding machine, comprising: a dressing control means that outputs a dressing execution signal when the amount of uneven wear is equal to or greater than a limit amount of uneven wear. (2) In a dressing device for a grinding machine that has a grinding wheel head that supports a rotatable grinding wheel shaft with a grinding wheel attached to the tip, the grinding wheel head is arranged in a direction perpendicular to the axis of the grinding wheel shaft with a grinding wheel attached to it, and On the other hand, there is a grinding wheel diameter detecting means that moves relatively in the axial direction of the grinding wheel shaft to detect the diameter of the grinding wheel along the axial direction of the grinding wheel shaft, and a grinding wheel diameter detection means that detects the minimum value of the grinding wheel diameter and detects the minimum value of the grinding wheel diameter. A wear amount calculating means calculates the amount of wear of the grinding wheel by comparing it with the diameter of the grinding wheel, and a wear amount calculated by the wear amount calculating means is compared with a pre-stored limit wear amount, and the wear amount is determined as the limit wear amount. A dressing device for a grinding machine characterized by comprising a dressing control means for outputting a dressing execution signal at the above times.
