气缸体缸孔和止口加工原需三道工序——粗镗半精镗缸孔和止口、精镗缸孔和止口、精刮止口,由三台组合机床分别完成。之所以用单独一台机床加工止口,是为了保证止口的深度精度13_(-0.02)~(+0.08)。 为了提高生产效率和减轻工人劳动强度,我们将精刮止口的工序与精镗缸孔和止口的工序合并,止口深度精度是通过采用北京机床电器厂生产的JSB—1型半导体时间继电器和其它一些措施来保证的。
Cylinder bore hole and the mouth of the original three-step process - rough boring half fine boring hole and stop, fine boring cylinder bore and only mouth, fine scraping stop mouth, completed by the three sets of machine tools. The reason why using a single machine tool to stop the mouth, is to ensure that the depth of the mouth of precision 13 _ (- 0.02) ~ (+0.08). In order to improve production efficiency and reduce labor intensity, we will be fine scraping the mouth of the process and fine boring cylinder bore and the mouth of the merger process, the depth of the mouth depth precision through the use of Beijing Machine Tool Electric plant production JSB-1 semiconductor time relay And some other measures to ensure that.
