(A) Applying a voltage between an electrically conductive grindstone (1) and a shaping electrode (4) for shaping the grindstone, generating a spark on a contact point by contacting the shaping electrode to the grindstone, thereby shaping the grindstone by the spark, and (B) simultaneously applying a voltage between the grindstone and a dressing electrode (2) for dressing the grindstone that is oppositely aligned to the grindstone without contact, supplying the electrically conductive grinding fluid between them, thereby dressing the grindstone by electrolytic dressing. According to these steps, highly efficient and simultaneous processing is achieved to provide a high precision profiling high quality mirror.
