摘要
针对某大型飞机轴类零件深孔加工粗糙度差、轴线偏差和切屑不易控制等问题,进行了Ti6Al4V钛合金枪钻加工试验,测试了枪钻加工深孔的轴线偏差、孔径误差和加工表面完整性,并分析了产生偏差的主要原因。从而优化了Ti6Al4V钛合金枪钻加工工艺参数,得到了Ti6Al4V钛合金17深孔枪钻加工最佳工艺参数,最终实现了860mm深孔的枪钻加工,使得最终综合误差控制在0.2mm以内,表面粗糙度Ra小于1.6μm。
For the problems of bad surface roughness, chip control and axis deviation, the experiments on gundrilling of Ti6A14V titanium alloy are carried out during deep hole drilling of the shaft parts of a certain large aircraft, the axis line deflection, diameter error and surface integrity are measured and the reasons of these errors are analyzed. The optimized process parameter is obtained in gun drilling process of Ti6A14V titanium alloy with a hole diameter of 17mm. A hole of 860mm deep is finished, while the comprehensive error is smaller than 0.2mm and the surface roughness is less than 1.6μm.
