DIAMOND DRESSING BLOCKS

Vitrified grinding wheels with Silicon Carbide, Aluminium Oxide, Diamond or CBN as grinding media loose their profile accuracy and cutting capacity after extended use. In order to restore the same, the grinding wheels have to be subjected to a dressing process. At present, cylindrical grinding wheels or wheels having simple profiles are dressed by means of diamond-single-grit dressers, diamond-multiple-stone-dressers, or by means of diamond-dressing plates, in a tolerance range of +/-0.05 mm. For higher precision requirements like +/-0.005mm and especially for complicated profile shapes, the dressing of grinding wheels can be accomplished only by highly precise diamond rolls.
