摘要：枪钻前端面的几何角度影响过油孔里切削液的流动方向及压力分布，不合理的磨削面将加剧刀具磨损和降低加工质量。本文分析了冷却剂的流动特性，通过改变枪钻前端面的刃磨角度进一步优化过油孔的位置，并用Fluent软件仿真进行了分析对比，定性了解枪钻前端面的几何位置对排屑流场的影响，得出最优的几何位置。经试验，加工效果良好。

Abstract:The geometric angle of the front face of the gun drill directly affects the flow direction and pressure distribution of the cutting fluid in the oil hole，and the unreasonable grinding surface will aggravate the tool wear and reduce the processing quality.Followed by changing the gun drill on the front end face of the grinding angle，the coolant flow characteristics are analyzed.To further optimize the oil hole position，the geometric effect of qualitative understanding of the front end of the gun drill cuttings flow are analyzed by Fluent software simulation.The optimal geometric position is obtained，and the experimental machining is carried out and good machining results are obtained.
