[0002] In the process of processing wooden doors, in order to improve the feel of the edges of the wooden doors, it is necessary to grind the edges and corners of the wooden doors. According to the patent authorization announcement number: CN216883127U, a wooden door edge grinder is proposed. The utility model can provide a structure for limiting the board by setting a limit frame and a matching auxiliary structure. The position of the edge of the board can be limited to ensure that the board is in a vertical state when cutting. When processing the board, there will be no situation where the angle is wrong due to misoperation of the edge, and different cutting mechanisms can be installed to replace the grinding and cutting functions. The structure is simple and the operation is convenient, which not only reduces the possibility of operating errors, but also eliminates the need for auxiliary marking operations for grinding.
