[0038] At the same time, the No. 1 telescopic cylinder 8 in the L-shaped plate 6 can adjust the length of the telescopic strip 9 in the plate groove 7, so as to control the lateral position of the grinding disc 12 on the ductile casting body 22, and the No. 1 servo motor 3 can control the position of the L-shaped plate 6 in the moving groove 4 by rotating the No. 1 threaded rod 5, so as to control the longitudinal position of the grinding disc 12 in the ductile casting body 22, so that the grinding surface of the grinding disc 12 can fully grind the upper end surface of the ductile casting body 22, thereby improving the grinding accuracy of the grinding surface of the grinding disc 12 on the upper end surface of the ductile casting body 22;

[0039] Finally, when the ductile iron casting body 22 is polished, the debris generated by the polishing will float in the air and on the base 1. At this time, the industrial vacuum cleaner 21 is started to clean the debris generated by the polishing of the ductile iron casting body 22 to protect the working environment from pollution.
