PURPOSE:To prevent the partial wear of respective sintered abrasive material layers so as to prolong the life of the captioned saw by interposing spacers between attaching members having the sintered abrasive material layer while making it possible to side and rotate the attaching members around wire core materials CONSTITUTION:A diamond wire saw 100 is formed in such a way that plural attaching members 2 provided through wire core materials 4 is made to slide and rotate around the wire core materials when the strong reaction force is applied on the attaching members in grinding. Around the outer periphery of the attaching members 2, sintered abrasive layers 1 obtained by sintering diamond abrasive grain with a binder is forcibly adhered. |
