摘　　要：排屑性能是评价钻头性能的一个重要指标,而钻头的容屑槽结构对其排屑性能影响很大。本文对可转位浅孔钻的容屑槽进行改进,提出了一种带偏心距的容屑槽。通过运用有限元分析及试验对比,证明其在保证刚度的前提下增大了容屑空间,提高了排屑性能。Chips discharging performance is one of the most important factors to evaluate the drill＇s cutting performance,and the structure of the chip flute has a great effect on chips discharging performance.Improved the chip flutes on the similar domestic products,put forward the chip flute deviated the axis.It proved by finite element analysis and the experimental comparison that the chip flute space was increased under the precondition of ensuring stiffness and its chip discharging performance has been improved.
