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.
