The structure of the grinding device is shown in Figure 1. It is composed of left and right holders 1 and 6, a bottom plate 7, an L-shaped holder 4, a fixing screw 5, a cemented carbide sheet 9, a micromotor 10, a pulley 11, a flat belt 12, and the like. A micromotor 10 is mounted on the rectangular bottom plate 7, and the power is transmitted by the flat belt 12. Supporting the workpiece 3 with the AB of the L-shaped support 4, and the workpiece 3
