Generally, in the case where the centering assembly 400 is not provided, after the workpiece is cut, the workpiece at the upper end of the cut is shaken due to the release of the tension of the workpiece itself, and thus a cutter collision is caused, and thus, the end workpiece is kept stable after cutting on the basis of the provision of the centering assembly 400, thereby avoiding the cutter collision.

In this embodiment, the first centering block 402 and the second centering block 404 are also disposed oppositely, the motion paths of the two centering blocks are straight lines, and the two straight lines coincide with each other, so that stable clamping and centering are achieved at two ends of the workpiece, which is the same for the fixed clamping block 303 and the movable clamping block 304.
