Abstract

PURPOSE: To improve the strength of a metal-bonded grindstone wheel against impacts by fixing a blade on a surface including a group of outer through-holes arranged in an outer peripheral edge portion of a metallic disc and on the wall of each of the through-holes.
CONSTITUTION: Outer through-hole group 2 and inner through-hole group 3 are formed in two arcuate rows at an outer peripheral portion of a metallic disc 1. On the surface of the outer peripheral portion of the metal disc 1 including the outer through-hole unit 2 and inside of each outer through-hole 4, a mixture of various metal powder and abrasive powder is applied and then sintered under pressure, thereby bonding a blade 5 to the metal disc 1. Therefore, since the blade 1 is bonded to the surface including the outer through-hole unit 2 the walls of the through- holes 4, the sintered material at an upper and lower faces are united into an integral body, thus being strong against impacts. A great cooling effect can be obtained as the inner through-hole unit 3 is exposed as is.
