Furthermore, cooling water is axially introduced through the water inlet dynamic seal 6, flows out of the radial circumferential multi-hole outlet 200 and is distributed in the pipe workpiece. The cooling water is turned from the inner part of the pipe workpiece to the axial direction from the circumferential radial porous water drainage hole 300, and returns to the cooling system through the water outlet dynamic seal 7.

Furthermore, the synchronous moving dust collecting air port 4 consists of a roll shaft and a flexible material, is driven by a synchronous motor 14, can synchronously move left and right along the front auxiliary guide rail and the process spray gun, and the tail end of the dust collecting air port is connected with an industrial dust removal system.

When a hollow workpiece is processed, the workpiece is directly sleeved between the axial rotation radial water-cooled flexible positioning driving shaft and the radial rotation axial water-cooled flexible positioning driven tailstock. Therefore, the workpiece is an outer cavity part of the sealed cavity, a complex mandrel is not arranged inside the workpiece, and cooling is more sufficient.
