METHOD AND APPARATUS FOR POLISHING DIAMOND AND DIAMOND COMPOSITES

摘要

A method and apparatus for polishing a diamond material is disclosed. The method comprises the steps of positioning a sample of the diamond material in relation to a movable metallic surface, and bringing the diamond material sample into contact with the movable metallic surface with simultaneous movement of the metallic surface and rotation of the diamond material sample. Two or more samples of the diamond material can be evenly spaced around a circumference of an imaginary circle centred on an axis of movement of the metallic surface, to be brought into contact with the movable metallic surface whilst moving the metallic surface on its axis. The apparatus can comprise a drive arranged to effect such movements, as well as a lift and place mechanism to constrain sample movements.
