当今采用机械手对曲轴箱、气缸盖和其它这类铸件进行抛九清理正不断取得进展。装有机械手的抛九机正逐步取代传统的带吊架式笼的抛九设备。这种变化的原因很明显，把有内腔和开孔的发动机机体和其它铸件挂在吊架上进行抛女清理，其结果会不尽人意，这是因为磨料丸粒会堵进内脏? There are ongoing advances in the use of robots to clean the crankcase, cylinder heads and other such castings today. Nine robots equipped with robots are gradually replacing the traditional nine equipment with hanger cage. The reason for this change is obvious. Hanging the engine block and other castings with lumens and holes on the hanger for cleaning women and girls will result in unsatisfactory results, because the abrasive pellets will block the internal organs.
