A nut with a suitable limit ring is selected according to the specifications of the processed tube. At the same time, the tube limits the rotation of the limit ring to prevent the bolt from rotating. The rotating nut is rotated to ensure that the support assembly does not rotate. At the same time, the lifting screw rotates and rises and falls along the rotating nut until the tube is supported to a suitable height, and the bolt stops rotating.

[0025] When using auxiliary tools, the number of auxiliary tools can be increased or decreased according to the length of the pipe, the position of the support assembly and the height of the limit ring can be adjusted to ensure that the center of the limit ring is concentric with the chuck of the lathe, and the pipe to be processed is inserted to process the pipe end bevel or internal boring.
