钛合金钻削加工及其新发展

从钛合金自身的切削加工性能出发,系统介绍了钛合金的切削加工基本原则。阐述了传统钛合金在钻削加工中常出现的几点问题:钻头材料、钻头几何参数分析和冷却介质的选择。根据钛合金的导热率低、弹性模量低、硬度较低和化学活性强等特点合理地调整钻头材料的选择,对原有钻头几何参数进行优化,正确选取冷却介质。并介绍了当前钛合金切削加工技术的新发展。

Titanium Alloy Drilling and New Development

From the titanium alloy cutting performance,the basic principles of titanium alloy cutting is introduced.And expounded several problems about the traditional titanium alloys drilling:bit materials,bit's geometric parameters of choice and the choice of cutting medium.Selecting suitable bit materials and cutting medium,optimizing the original bit geometric parameters according to the low thermal conductivity,low modulus of elasticity,hardness and lower chemical activity of titanium alloys.At last it made an exposition of the new development of current titanium alloy cutting technology.
