从深孔中吸取切屑往往比较困难。若将右图所示吸取器的黄铜小管插入深孔里,当水平大管通人压缩空气后,比黄铜小管直径小的碎屑即被吸上来,由大管中的压缩空气吹走。而较大的切屑则被吸附在黄铜小管底部,在切断压缩空气,将黄铜小管从深孔中取出时,较大的切屑便一起带出来了。深 Drawing chips from deep holes is often difficult. If the brass suction pipe shown in the right picture is inserted into the deep hole, when the horizontal pipe passes the compressed air, the smaller diameter of the brass pipe will be sucked up and blown away by the compressed air in the large pipe . Larger chips are adsorbed at the bottom of the brass tube. When the compressed air is cut off and the brass tube is removed from the deep hole, larger chips are brought out together. deep
