Abstract

PURPOSE: To improve durability of a disc type abrasive stone by bonding a cutting edge on the surface of each tooth-shaped mounting part at its top portion other then its root portion and the walls of each groove formed at an outer peripheral portion of a metallic disc.
CONSTITUTION: An outer peripheral portion of a metal disc 1 is cut off radially to form a gear shaped cutting-edge mounting part 2. A cutting edge 6 is bonded to a top part 4, excepting a root part 3, of a cutting-edge mounting part 2 and the walls of a groove 5 by a method such as press-sintering a mixture of various kinds of metal powder and abrasive powder. The root part 3 and the grooves 5 of the cutting-edge mounting part 2 where the cutting-edge 6 is not bonded is left uncovered. Therefore, a sintered material on an upper and lower faces of the disc 1 are united together to protect the cutting-edge against impacts and the prevent it from falling off, and, as the root parts 3 of the gear shaped cutting-edge mounting parts and the grooves 5 are left uncovered, the large cooling effect is obtained and the removal of chips can be simplified.
