摘　　要：根据出油阀阀芯的加工特性,针对存在问题从阀芯基准中心孔修正工艺、MG1312精密磨床硬质合金顶尖工作锥面技术要求以及阀芯磨削过程中的光磨工艺环节三个方面提出提高出油阀偶件加工精度的改进办法.取得了良好效果,明显提高了产品的质量和合格率.The outlet valve mates is a pair of important parts in engine fuel pump, it has high manufacture precision. According to the manufacture characteristic of its spool valve, three improvements are brought up for the present problem in this paper ,which are of the correction of center bore, the technical requirements of the working cone of carbide alloy in MG1312 grinder and the non-feed grinding. These improvements result in good effect on a raise of the quality and qualification rate.
