2 use compressed air to blow off the iron filings in the pipe;

3 Turn on the deburring machine gas motor air source switch, check whether the tool length is long enough or not;

4 Pull the tool holder to move the switch axially. When the tool reaches the pipe body, twist the air motor switch tool to rotate at high speed immediately, then adjust the tool axial movement speed (usually 0.7--1 m per minute) until the tool passes over the pipe. All the holes in the wall, reversely move the tool holder to move the switch tool axially backwards until the air motor switch closes the pipe end and immediately shuts off the air motor. The tool is still moving axially. When the starting position is reached, the tool shaft is pulled. Move the switch to the stop position;

5 Use compressed air to blow off the iron scraps in the tube. Check whether the inner wall burrs are cleaned by hand-held flashlight. If it is determined that the burrs are removed, the process will be transferred to the next step. If it is not qualified, the tool or axial movement speed should be adjusted and the above process repeated. Until the burr is removed;

6 good thread protector at both ends;

7 Fill in the relevant records.
