Abstract (en)
Relatively hard grade, high strvcture cold-formed organic-bonded abrasive bodies such as metal grinding, snagging and cut-off wheels have abrading portions of improved life and efficiency comprising, by volume, 30 to 44% of 12 to 100 grit size abrasive particles, 24 to 36% thermosetting resin, 14-29% active filler material and 6-18% pores and, wherein the active filler replaces reductions in abrasive content when going to a higher structure and thereby increasing the volume ratio of filler to both the abrasive and resin contenL The preferred ratios are in the range of 1 volume of filler to .8 to 2.6 volumes of resin and 1.0 to 3.2 volumes of abrasive.
