[0021] When grinding the workpiece, the staff fixes the workpiece with a vise and places the vise on the mounting frame 2 at the upper end of the base plate 1 to fix the position of the workpiece. Then, the staff adjusts the adjustment and positioning assembly to a specified height according to the grinding depth of the workpiece. Then, the two first linear modules 3 change the overall height of the moving frame 4 and the grinding motor 9, and the grinding motor 9 rotates at high speed to contact the surface of the workpiece, and the upper surface of the workpiece is fully ground. During the grinding process, the second linear module 5 located at the upper end of the moving frame 4 works reciprocatingly, driving the sliding block 8 and the grinding motor 9 to reciprocate at the upper end of the slide rod 7, and reciprocating grinding is performed on the workpiece to ensure the smoothness of the workpiece surface, until the limit frame 16 at the lower end of the moving frame 4 contacts the adjustment and positioning assembly to complete the surface grinding operation of the workpiece.
