The titanium alloy tube 9 on the fixed chuck 3 moves towards the grinding cylinder 7 under the drive of the fixed chuck 3. When the grinding cylinder 7 is about to contact the titanium alloy tube 9, an external water supply device and a dust suction device are started. The external water supply device conveys water through the cooling connection pipe 85 to the cooling pipe 82, and finally sprays it on the inside and outside of the titanium alloy tube 9 from the atomizing nozzle 83. As the cylinder continues to propel the titanium alloy tube 9, the grinding cylinder 7 extends into the titanium alloy tube 9 to contact and grind the titanium alloy tube 9. At the same time, the atomizing nozzle 83 continuously sprays water mist for cooling. Part of the dust and debris generated during grinding are adsorbed by the water mist, and the other part is sucked into the collection holes 84 on the cooling column 8 and conveyed to the external dust suction device through the dust removal connection pipe 86. After the grinding is completed and the propulsion cylinder 21 is controlled to move the titanium alloy tube 9 out of the grinding cylinder 7, part of the water mist inside the titanium alloy tube 9 condenses into flowing water on the wall of the titanium alloy tube 9 and carries part of the dust and debris to flow out from the mouth of the titanium alloy tube 9 and fall on the grinding body 1 and flow into the diversion grooves 111, and the diversion grooves 111 guide the water into the waste liquid box 112 for collection.
