摘要
通过对国内外ＰＤＣ钻头和金刚石钻头设计现状的调查，认为这两类钻头共有四种基本冠部剖面形状（浅锥型、双锥型、抛物线型和“Ｂ”型），提出了相应的四种钻头设计基本模式，探讨了各种模式适用性和所设计钻头特性。
This article summerizes four basic crow profiles by studying crown profiles of existing PDC bits and diamond bits at home and abroad.The article also develops four design models of crown profiles which can be used for two styles bits' design, and abtains series of formulae.
