Truing method for grinding wheel
In a grinding machine comprising conductive grinding wheels, the invention presents a truing technique capable of truing grindstone surfaces of grinding wheels at high precision in a short time.For example, in the case of truing flat annular grindstone surfaces (10a, 10a) of a pair of mutually opposite grinding wheels (1, 2) simultaneously, an electro-discharge truing electrode (20) is disposed oppositely between the grindstone surfaces (10a, 10a) of the two grinding wheels (1, 2), and while traversing relatively parallel along the both grindstone surfaces (10a, 10a), the grindstone surfaces (10a, 10a) are trued without making contact by the electro-discharge action between the electro-discharge truing electrode (20) and both grindstone surfaces (10a, 10a).
