摘　　要：麻花钻头是孔加工的常用刀具,针对各种不同类型孔的钻削要求,钻孔前根据需要提前刃磨钻头。另外钻头长期使用也会有不同程度的磨损和钝化,为更好发挥钻头的切削效率,提高钻头的使用寿命,减省操作者的劳动强度,就需要科学地刃磨钻头,钻头因为切削刃较多和各角度复杂,磨削钻头要求高、难度大,本文详细论述了麻花钻头磨削的基本方法和各种注意事项。Twist drills are commonly used tools for hole processing.According to the drilling requirements of various types of holes,sharpen the drills in advance as needed before drilling.In addition,the long-term use of the drill will have different degrees of wear and dullness.In order to better exert the cutting efficiency of the drill,increase the service life of the drill,and reduce the labor intensity of the operator,it is necessary to sharpen the drill scientifically.The cutting edge of the drill is there are many and complex angles,and the requirements for grinding drills are high and difficult.This article discusses in detail the basic methods of twist drill grinding and various precautions.
