摘要: A highly accurate, long-life grindstone for shaping a gear and a method of fabricating the grindstone, without depending on the accuracy of form of a base metal and without using a special grinding machine or a special lapping machine, are disclosed. A super-abrasive layer (29) of a predetermined thickness is fixedly attached on the outer periphery of a body portion (24) of the base metal (23) formed in a cylinder solid. The super-abrasive layer (29) is metal-bonded, and has the outer periphery thereof formed with a toothed portion (31) in the shape of the teeth of an external gear by electric discharge machining.
