Abstract
A technique for finishing a diamond ground outer surface (14) of a hot glass sheet conveyor roll (16) made of sinter bonded fused silica particles utilizes a continuous abrasive belt (26) to perform a finish grinding process on the outer surface. The process is performed by rotating the roll (16) about a central axis A thereof and driving the continuous abrasive belt (26) so as to finish grind the roll while moving the driven belt along the roll length. Silicon carbide is preferably utilized as the abrasive of the belt (26). The belt is preferably driven so as to engage the rotating roll surface (14) in an oppositely moving relationship and is moved in both directions along the length of the roll. During the finish grinding, the roll is flooded with water to provide a lubricant that dissipates heat and removes ground off particles. The ground outer surface (14) includes projections (55) having top surfaces (56), sloped sides (58), and curved junctions (60) connecting the top surfaces and the sloped sides.
