During the machining process, a large cutting force is required, resulting in large machining deformation. The characteristics of this part are large diameter and thin wall, and its dimensional tolerance requirements are extremely high, which poses a great challenge to the clamping and machining of the part. In terms of usage requirements, it requires high wear resistance, high temperature resistance, and high rotational speed resistance, resulting in extremely high dimensional tolerance requirements. During the machining process, strict dimensional tolerance must be ensured, which also makes the machining of this part very difficult. Content of the Utility Model
