摘　　要：作为一种典型的难加工材料,高锰钢的加工硬化现象很严重,加工性能很差,特别是钻削时刀具容易破损,加工效率低下。本文基于工厂实地调研,详细分析了导致钻头破损的各方面原因,并针对工厂现实情况提出了改进措施与设想,为减少刀具破损,提高生产效率提供了科学依据。Abstract： High manganese steel is a typical of hard machining material. It has the characteristic of high strength, hardness and good wearing ability, so it＇ s machining is poor, mostly because tool＇ s wearing and machining efficiency is very low. This article focuses on dry cutting for ZGMnl3 high manganese steel and through plenary academic analysis andscientific experiments, to improve Carbide drill with Multi facet on the geometric parameters and the structure. This provides scientific basis for the high manganese steel＇ s drilling.
