Truing method for grinding wheel, its truing device and grinding machine
A method and apparatus are used for truing grindstones. Grinding wheels are arranged in a manner such that the respective grindstone surfaces are disposed apart from each other to define a space therebeween and respective ones of the grindstone surfaces are positioned in respective planes with the planes extending parallel to each other. Each grinding wheel is composed of a conductive grindstone having abrasive grains bound by a conductive binding material. An electrode discharge is applied from an electro-discharge truing electrode disposed in the space between the grindstone surfaces in a non-contacting relationship with the grindstone surfaces. The electrode discharge occurs in respective gaps formed between the electro-discharge truing electrode and the grindstone surfaces. The electro-discharge electrode is moved relative to the grindstone surfaces while applying the electrode discharge so that the grindstone surfaces are trued thereby.
