前言精密深孔的高速钻削,目前仍是关键工艺技术,对孔径为20毫米以下的深孔而言,用外排屑枪钻(以下简称枪钻)钻削是一种高效经济的方法。鉴于这方面的资料较为缺乏,本文将介绍枪钻结构尺寸的给定,切削角度的选择以及刃磨内切削角时进给量的计算方法,并列表给出了刃磨枪钻时的工艺参数。 Foreword Precision deep hole high-speed drilling, is still the key process technology, the hole diameter of 20 mm below the hole, the use of external chip gun gun drilling (hereinafter referred to as gun drill) is an efficient and economical method. In view of the lack of information in this area, this article will introduce the given size of the gun drill structure, the choice of cutting angle and sharpening cutting angle within the calculation of the amount of feed, and lists the diamond grinding process parameters .
