[0027] Specifically, when punching a hole in a flange-type ductile iron casting, the flange-type ductile iron casting is first clamped and fixed by an existing fixture so that the flange-type ductile iron casting is located between the two circular blocks 6. Then, the L-shaped rod 11 is started, and the two circular blocks 6 are driven to move toward each other by connecting the circular plate 5 and the L-shaped rod 11, so that the grinding portion is close to the two ends of the flange-type ductile iron casting.
