[0035] When using, first check the status of the deep hole processing tooling of the machining center to ensure that all components are intact, especially the key components such as the positioning plate 1, the gas cylinder 3, the fixing frame 9, the positioning frame 2, the telescopic tube 5, and the piston rod 6.
