During the workpiece processing, the debris will accumulate on the surface of the worktable 7. After the workpiece is processed, the drive mechanism 6 can be started to tilt the arched table 5 at a certain angle. At the same time, the rotation mechanism 9 is controlled to make the worktable 7 rotate according to the preset angle and speed. The air pump mechanism 10 blows the debris on the surface of the worktable 7.
