Therefore, the method of cleaning the debris by exhausting air from the back of the bushing is not reasonable; and the internal thread of the bushing will block the debris after it is formed, and the metal debris has a certain gravity and is not easy to be extracted from the bushing; and because the temperature of the processed bushing is high or it is stained with coolant, it is inconvenient to manually take down the bushing and knock it to remove the internal debris.

The input end of the translation electric cylinder 81 and the input end of the positioning electric cylinder 61 are both connected to the output end of the second controller. The translation electric cylinder 81 is closed when it receives the positioning signal, and the positioning electric cylinder 61 drives the plug 62 to be inserted into the slot 41 when it receives the positioning signal.
