Abstract
A tool is constructed by a plurality of diamond columns 22 arranged so as to protrude from a working surface and a conductive bond member 24 for integrally fixing the diamond columns. The conductive bond member is electrolytically dressed while a conductive liquid is supplied between the bond member and an electrode 4 which faces the bond member at a distance, thereby enabling the diamond columns 22 to protrude. By this construction, the tool can be applied to both an efficient rough cutting for a ductile material and a precise grinding for a brittle material without detaching or re-attaching a workpiece, the relatively soft ductile material such as aluminum, copper, or plastic can be worked with a deep cut, the brittle material such as monocrystal silicon, glass, or tungsten carbide can be efficiently and stably ground, so that a fluctuation of a working position due to wear can be compensated.
