我厂某产品上一个小套筒零件,其材料是H62-y。该零件需要在横方向上加工两个对称度要求高的型孔。从而保证带有横销的套管零件在其内孔中松动地轴向运动。为达到此目的,采用以下三种加工方法:
I plant a product on a small sleeve parts, the material is H62-y. The part requires two holes that require high symmetry in the cross direction. This ensures that the sleeve part with the cross pin is loosely moved axially in its bore. To achieve this goal, the following three processing methods:
