Specifically, when in use, the arc-shaped glass panel 18 is placed on the sliding plate 15 and the position is adjusted. The first motor 31 is used to drive the grinding rods 32 to rotate and gradually approach the glass panel 18 to grind the glass panel 18. During the grinding process, the first driving device is used to drive the sliding plate 15 to drive the glass panel 18 to make an arc-shaped reciprocating motion around the center of the glass panel 18.
