我厂生产的气缸盖在精加工阀座、导管底孔以后,压入导管、阀座,然后在DX4自动线上的倾斜式多轴组合机床上进行阀座锥面加工和导管孔镗挤加工。要求加工后保证阀座锥面对导管孔中心线的径向跳动不大于0.05,导管孔尺寸为φ99.50~(+0.03) ,光洁度7,孔的不直度不大于0.01/100,孔的中心线对底平面的不垂直度不大于0.1/100。这些技术要求,自从
The cylinder head produced by our factory is pressed into the guide pipe and valve seat after finishing the valve seat and the bottom hole of the guide pipe, and then the valve seat conical surface processing and the catheter hole boring and squeezing processing are performed on the inclined multi-axis combined machine tool of DX4 automatic line. After machining, it is required to ensure that the radial runout of the cone of the valve seat on the centerline of the catheter hole is not more than 0.05, the diameter of the catheter hole is φ99.50 to (+0.03), the finish of the instrument is 7, the degree of straightness of the hole is not greater than 0.01 / 100, The center line of the bottom plane of non-perpendicularity is not greater than 0.1 / 100. These technical requirements, since
