Abstract

PURPOSE: To reduce manhours for manufacturing a cutting grindstone, by stuffing a mixture of diamond abrasive and metal powder around the periphery of a mounting disc in a metal mold so as to form an intermediate molded article and then by disposing the latter in a calcining metal mold for calcining the same in the reducing atomosphere.
CONSTITUTION: A disc 11 is arranged between an upper die 12 and a lower die 11 of a metal mold 7. A mixture of metal powder 19 and diamond abrasive 18 in a predetermined amount is stuffed in portions, corresponding to segment chips 6 of a cutting grindstone, of the metal mold 7, and is then compressed by a press machine so as to form an intermediate molded article of the disc 1 having the segment chips 6 compressed to predetermined dimensions. Such a disc 1 is calcined in a calcining furnace of piled-up layer type in the reducing atmospher (hydrogen), thereby to manufacture cutting grindstones with high efficiency.
