摘　　要：深孔加工是机械加工过程中难度较大的工序之一。深孔加工需在密闭环境中进行,排屑困难,热量不易散发;刀具系统长径比大、刚度低,容易引起振动,影响深孔的直线度和表面粗糙度,导致刀具使用寿命下降,因此有必要对深孔加工方法、切削工具和质量监控进行研究。基于深孔加工的概念和原理,阐述了深孔加工技术研究情况,并结合生产需求分析了深孔加工技术的未来发展方向。Deep hole machining is one of the difficult processes in machining process.Deep hole processing needs to be carried out in a closed space environment,chip removal is difficult and heat is not easily dissipated.The tool system has a large aspect ratio and low stiffness,which easily causes vibration and affects the straightness and surface roughness of deep holes,resulting in a decrease in tool life.Therefore,it is very necessary to study its processing methods,monitoring methods and detection methods.Based on the concept,and principle of deep hole machining,this paper summarizes the technical research status,and prospects the development direction of deep hole machining in the future.
