密封座的封严表面,光洁度要求高,平直度要求严,需用研磨加工来达到。在我们新品生产中,有几种密封座,用内孔底面封严。设计要求光洁度▽10,平直度不大于0.001,材料是1Cr13(见图1)。这种精度高材料软的零件,用普通方法研磨难达到设计要求。我们设计制造一个研磨工具,经几种零件加工都满 Sealing seat sealing surface, high requirements of smoothness, flatness demanding, the need to use grinding to achieve. In our new production, there are several kinds of seal seat, with the bottom of the hole sealed. Design requirements finish ▽ 10, flatness is not greater than 0.001, the material is 1Cr13 (see Figure 1). This high-precision materials, soft parts, grinding with ordinary methods difficult to meet the design requirements. We design and manufacture a grinding tool that is finished with several parts
