Abstract

PURPOSE: To obtain a means of forming abrasive grain to be hard to fall off as well as to give favorable sharpness in such a way that the grinding stone is constituted by arranging acerose abrasive grain.
CONSTITUTION: Acerose abrasive grain covered by magnetic material is scattered through a feeding mechanism on a tape-shaped sheet 2 composed of paper, cloth or the like. Then, when an upper mold 33 is sent down, a split mold 32 is slid in the outer diametral direction, a rolled sheet 2 is compressed by an upper mold 27 and the split mold 32 and heated by a heater 26, then thermosetting resin solution which is adhered on the sheet 2 and set thereon is dissolved again, after that it is set under heat, it is incorporated with the sheet 2 to form a grinding stone body, which has its one end in the axial direction tightly adhered to the rough face 30a which is formed on the part 30 to fix a pedestal 29. Therfore, acerose abrasive grain of grinding stone become the condition to arrange it perpendicularly to be worked face of the other end in the axial direction of the grinding stone body. Thus, abrasive grain to be hard to fall off as well as to give favorable sharpness can be obtained.
