sandpaper, abrasive originally made by gluing grains of sand to heavy paper sheets. Today sandpaper is made primarily with quartz, aluminum oxide, or silicon carbide grains, and is graded according to the size of the grains. It is used for smoothing and polishing, for removing old paint or varnish, and for otherwise preparing wood surfaces for refinishing or other treatment. |

Technicians should use a double-ended grinder for rough polishing, abrasive paper (starting at 120, then 240, 400 and 600 grit) for sanding, and diamond or alumina abrasives for final polishing. NBS abrader--square blocks of specified dimensions are run against abrasive paper of a given grit size mounted to a drum rotating at 4. The blanket cylinder also extends the life of the already rugged imaging cylinder, which doesn't come in contact with abrasive paper surfaces. |
