The second gantry robot 121 rises, and the flipping motor 71 drives the flipping shaft 72 to rotate, causing the annular workpiece 10 to flip 180°. Then, the second gantry robot 121 descends to grip the annular workpiece 10, and the clamping plates 75 move away from each other until the annular workpiece 10 is released from the clamping plates 75. Then, the second gantry robot 121 rises and moves the annular workpiece 10 above the second positioning circular plate 68. Then, the second flip plate 681 opens, the second moving plate 682 retracts, and the second gantry robot 121 lowers the annular workpiece 10 onto the second positioning circular plate 68. The second gripper cylinder 69 presses against the inner wall of the annular workpiece 10. Then, the third translation module 63 drives the outer grinding head 61 to move to the outside of the annular workpiece 10, and the third lifting module 62 drives the outer grinding head 61 to descend to the position for grinding the outer circumference of the annular workpiece 10. The fourth translation module 66 drives the second upper grinding head 64 to move above the annular workpiece 10, and the fourth lifting module 65 drives the second upper grinding head 64 to descend to the position for grinding the top surface of the annular workpiece 10. Then, the outer grinding head 61 and the second upper grinding head 64 start, and the corresponding grinding wheels rotate. The second rotary motor drives the second positioning circular plate 68 to rotate, so that the annular workpiece 10 rotates one revolution, and the outer grinding head 61 and the second upper grinding head 64 simultaneously grind the outer circumference and the flipped top surface of the annular workpiece 10.
