Claims

[Scope of utility model registration request]

A grinding table that is slidably provided on a fixed table is reciprocated by a cutting device, and a workpiece is ground by a grindstone that is rotatably provided on this grinding table. When the grindstone becomes worn, the grinding table In a grinding machine that corrects the grindstone using a grindstone grinding means provided at the tip of the dressing table by moving a dressing table that is slidably provided, the top end of the dressing table is The intermediate portion is rotatably supported by the grinding table so that the whetstone grinding means provided on the grindstone is located on an extension line of the circumferential surface of the whetstone having a regular diameter, and extends toward the dress white side and the fixed base side, Link members that can be held at positions with equal distances from the support point are provided, and the amount of movement of the dressing table with respect to the fixed table is twice the amount of movement of the grinding table with respect to this fixed table. A grinding wheel correction device for a grinding machine characterized by:
