After marking is completed, the marked part of the material is moved to just below the grinding disc 802. At this time, the fourth drive motor 809 is turned on. Under the action of the fourth drive motor 809, the second gear 807 rotates, thereby driving the rack plate 806 and the grinding disc 802 to move down and contact the top of the material. The third drive motor 801 is turned on, and the grinding disc 802 rotates under the action of the third drive motor 801, thereby grinding the top of the marked part.
