摘要： An ultrahard stone, such as a diamond gem stone, is cut or kerfed by moving the cutting edge of a diamond compact relative to and in contact with the stone. The diamond compact may be in the form of a disc with with a cutting edge thickness of 0.5 to 1 mm. Preferably, the diamond compact is thermally stable at 1200°C in an inert or non-oxidising atmosphere.
