[0002] The impeller refers to the wheel disk with moving blades, which is a component of the impulse steam turbine rotor, and can also refer to the general term for the wheel disk and the rotating blades installed on it. Impellers can be classified according to their shape and opening and closing conditions.

In addition, the existing impellers have different models and the curvature of the guide grooves are different. The commonly used chamfering devices cannot meet the processing requirements of impellers of different models. Therefore, a chamfering device that can adapt to various angles and shapes is needed.
