通过对铝高速钢与普通高速钢的红硬性对比试验以及铝高速钢、钴 高速钢与普通高速钢丝锥分别对比切削的试验研究,得出在普通高速钢 申添加Al、Co的超硬高速钢在螺纹工具一丝锥的应用中对其切削性能有 很大的提高。
By comparing the red hardness of aluminum high speed steel and ordinary high speed steel and comparing the cutting of aluminum high speed steel, cobalt high speed steel and ordinary high speed steel tap respectively, it is concluded that the addition of Al and Co in high speed steel In the application of a thread tap tools for its cutting performance has greatly improved.
