摘　　要：在分析某7075-T6硬铝合金深孔薄壁零件加工过程中存在的难点基础上,提出了采用深孔钻削和拉镗拉铰加工内孔,然后以内孔为定位基准加工外形,最后珩磨内孔至最终尺寸要求的方法,解决了7075-T6深孔薄壁零件的加工问题,保证了零件加工精度,完全满足加工需求。同时,该加工方法还可为类似零件的加工提供参考。Based on the analysis of the difficulties existing in the processing of a 7075-T6 hard aluminum alloy deep-hole thin-walled part,this paper proposes the use of deep-hole drilling and broaching and reaming to process the inner hole,and then the inner hole is used as the positioning reference for processing.The method of honing the inner hole to the final size requirements finally solves the processing problem of 7075-T6 deep hole thin-walled parts,ensures the machining accuracy of the parts,and fully meets the processing requirements.At the same time,the processing method can also provide a reference for the processing of similar parts.
