TECHNICAL FIELD

The magnetic ring product needs to be assembled into a motor after being magnetized, and the assembly size and the roundness of the product are very critical. For the product batch with a small inner diameter after manufacturing, in order to ensure that all the provided products meet the technical requirements of the customer drawings and facilitate the customer assembly, the inner diameter of the product needs to be shaped.
