FIXED ABRASIVE GRAIN WIRE AND WIRE PROCESSING METHOD

PROBLEM TO BE SOLVED: To provide an abrasive grain wire capable of improving sharpness and reducing a processing cost when an alloy containing iron of 45% or more such as an alnico alloy, a ferritic alloy, a samarium-cobalt alloy, a neodymium alloy and the like is cut and to provide a wire processing method using the same.SOLUTION: In an abrasive grain wire 2 using for cutting an alloy containing iron of 45% or more,: abrasive grains fixed on a wire 6 include both of diamond abrasive grains 7 and CBN abrasive grains 8; and an including ratio of the diamond abrasive grains 7 to the CBN abrasive grains 8 is 20:80-70:30. 【課題】アルニコ合金、フェライト合金、サマコバ合金やネオジム合金等の鉄を４５％以上含有する合金の切断に際して、切味の向上および加工コストの低減を可能にした固定砥粒ワイヤーおよびこれを用いたワイヤー加工方法の提供。【解決手段】鉄を４５％以上含有する合金の切断に用いられる固定砥粒ワイヤー２であって、ワイヤー６上に固定される砥粒が、ダイヤモンド砥粒７およびＣＢＮ砥粒８の両方を含み、ダイヤモンド砥粒７とＣＢＮ砥粒８との含有比率を２０：８０〜７０：３０とした。【選択図】図２
