花岗岩干切片锋利型配方研究(上)

Study on the formular of sharp diamond saws segments for dry cutting granite

文章主要研究用于花岗岩板材干切加工的金刚石圆锯片(外径105～125㎜)刀头配方,通过选用铁钴基预合金粉末及35/40粒度金刚石获得了一种比市场畅销的国内产花岗岩高档片和韩国产花岗岩高档片更经济、更锋利的配方,并指出结合剂较易及适度的磨损有利于锯片出刃,切速提高。

The paper mainly studied the diamond saws （Ф105- 125mm） segments formulating for dry cutting granite. Through using Fe and Co based prealloy powder bond and 35/40 grain size diamond, a more economical and sharper formulating was got than one made in inland and another made in Korea ready market granite top saw, and it was pointed out that the easier and moderate wear-down of the bond was to the benefit of high protrusion of diamond grains and faster cutting.
