本文针对钛合金深孔加工中出现的切屑堵塞、导向条表面粘附和已加工表面粗糙度值高等问题,通过机理分析和实验对比的方法,对加工钛合金大口径深盲孔的刀具设计原则和加工工艺方面进行了较全面的研究,较好地解决了断屑不良、已加工表面粗糙度值高等问题。 In this paper, for titanium chip deep hole machining chip jamming appears, the guide strip surface adhesion and processing of the surface roughness value is higher, through the mechanism analysis and experimental comparison of the processing of large diameter titanium blind hole blind hole tool design principles And processing technology conducted a more comprehensive study, a better solution to the poor chip breaking, the surface roughness has been processed the problem of high value.
