摘　　要：使用相同的金属胎体结合剂,通过半自动冷压和全自动冷压两种冷压工艺进行冷压制作金刚石串珠,并将两种方式冷压出来的金刚石串珠分别烧结成相同规格的金刚石串珠,并制作成长度一样的金刚石矿山串珠绳锯,采用同一台绳锯机,在功率相同的条件下,对花岗岩矿山石材进行现场切割,记录金刚石串珠绳锯每一次的切割效率。根据结果得出金刚石串珠在两种冷压方式下,两者在串珠外径相同时,串珠表面的金刚石数量有差异,而随着金刚石串珠直径从大到小变化,两种冷压方式生产的金刚石数量变化趋势也不相同,而金刚石串珠矿山绳锯对花岗岩的切割效率与串珠表面金刚石的数量具有一定的相关性,改变金刚石在径向上的分布对调整金刚石绳锯性能具有重大意义。With the same metal matrix binder,cold pressing is performed through two cold pressing processes,semi-automatic cold pressing and fully automatic cold pressing.In order to make diamond beads,the two cold-pressed diamond beads are respectively sintered into diamond beads of the same specification.The same length of diamond bead wire saw is produced.The same wire saw is used to cut the granite stone in the mine field under the same power condition,and the cutting efficiency of each diamond bead wire saw is recorded.According to the result,under the two cold pressing methods,the number of diamonds on the surface of the diamond beads is different when the outer diameter of the two beads is the same.However,as the diameter of diamond beads changes from the large to small,the trends in the number of diamonds produced by the two cold pressing methods are also different from each other.The cutting efficiency of the diamond bead mine wire saw on the granite has a certain correlation with the number of diamonds on the surface of the bead.There is a great significance to change the distribution of diamonds in the radial direction for the adjusting of the performance of the diamond wire saw.
