The biggest difficulty in grinding large-diameter thin-walled parts is that the parts are easily warped and deformed. After practice, we have explored a method for grinding large-diameter thin-walled parts. For example, when grinding a circular saw blade for cutting marble, the saw blade has a diameter of 450 mm, a thickness of 2_(-0.05) to 0 mm, and a parallelism of 0.02 mm (Fig. 1).
