摘要
为解决钻头在使用过程中因金刚石分布不均匀而产生的金刚石过早脱落,胎体拉沟、掉块等问题,研制出金刚石均布工艺,用该工艺生产的钻头,胎体中金刚石可达到等间距排列,取到了很好的使用效果.
Many troubles in diamond bit drilling are frequently encountered due to the nonuniform distribution of the diamond grains at the bit end. In order to get those troubles (such as the diamond too early to fall off from the matrix, matrix scratching and fragmenting, etc.) thrown away. the technology for making drilling bits with diamond grains uniformly distributed at the bit end in equal space has been developed. The bits manufactured by using this technology was achieved good tesults in practical use.
