DRESSER FOR ABRASIVE CLOTH

摘要

THE INVENTION PROVIDES A DRESSER FOR AN ABRASIVE CLOTH, WHICH HAS A SMALLER ABRASIVE GRAIN DIAMETER THAN THE CONVENTIONAL DRESSER AND HAS AN ABRASIVE GRAIN SPACING REGULATED IN A PREDETERMINED RANGE DEPENDING UPON THE ABRASIVE GRAIN DIAMETER TO SIMULTANEOUSLY MEET A HIGH LEVEL OF PAD GRINDING POWER AND A PAD FLATNESS AND, AT THE SAME TIME, IS LESS LIKELY TO CAUSE DROPOUT OF ABRASIVE GRAINS. THE DRESSER COMPRISES A PLURALITY OF ABRASIVE GRAINS FIXED AS A SINGLE LAYER ON A SURFACE OF A METALLIC SUPPORT MATERIAL. THE DRESSER IS CHARACTERIZED IN THAT THE METALLIC SUPPORT MATERIAL ON ITS SURFACE ON WHICH THE ABRASIVE GRAINS ARE FIXED HAS A CONVEX SHAPE, THE DIFFERENCE IN HEIGHT BETWEEN THE END PART AND THE CENTRAL PORT ON THE SURFACE IS NOT LESS THAN 3µM AND NOT MORE THAN 40µM, AND THE CENTER-TO-CENTER SPACING BETWEEN AT LEAST ONE SET OF ADJACENT GRAINS IS D=L<2D WHEREIN D REPRESENTS THE DIAMETER OF THE ABRASIVE GRAINS; L REPRESENTS THE CENTER-TO-CENTER SPACING BETWEEN ADJACENT ABRASIVE GRAINS. THE DIAMETER (D) OF THE ABRASIVE GRAINS IS PREFERABLY 3µM=D<100µM.
