金刚石钻头质量的好坏,与其在胎体中的分布状态有密切关系。采用一般的方法,不能制造出人造金刚石分布均匀的孕镶钻头。在工作层内,有的区域金刚石密度很大,形成密集区,有的区域则很稀,构成稀疏区。在密集区,由于金刚石堆集在一起,不能充分发挥每粒金刚石的磨削作用,从而降低了钻头的碎岩效率。另外,由于金刚石密度过大,还容易使金刚石过早脱落。在稀疏区,常会出现拉槽现象,从而降低钻头寿命。如能解决金刚石均匀分布的问题,则可避免上述现象,提高钻头上金刚石的利用率,节约每 Diamond bit quality is good or bad, and its distribution in the carcass are closely related. Using the usual method, it is not possible to produce a pregnant drill with a uniform distribution of synthetic diamond. In the working layer, some areas of diamond density, forming dense areas, and some areas are very thin, constitute a sparse area. In dense areas, the grinding of each diamond can not be fully exerted due to the accumulation of diamonds, thus reducing the biting efficiency of the bit. In addition, due to diamond density is too large, but also easy to make the diamond off too early. In the sparse area, often appear slot phenomenon, thereby reducing the bit life. If we can solve the problem of uniform distribution of diamond, you can avoid the above phenomenon, improve the diamond bit utilization, saving
