Aluminum flywheel casing machining process

The invention discloses an aluminum flywheel shell machining process which comprises the steps that firstly, a hole system and a face on one side of a machine body face of a flywheel shell are machined, in the first step, the flywheel shell is clamped on a machining clamp, and the machining clamp comprises a hydraulic clamp and a pneumatic pressing piece for pressing the far end of the flywheel shell; thirdly, hole series and faces on one side of the spigot face of the flywheel shell are machined; fourthly, the remaining to-be-machined faces on one side of the spigot face of the flywheel shell and the remaining to-be-machined hole series on one side of the spigot face of the flywheel shell are machined. And vibration of the far end in the machining process is effectively restrained through the pneumatic pressing piece, roughness changes caused by vibration are avoided, the flatness is guaranteed, and the machining precision and efficiency are effectively guaranteed. 本发明公开了一种铝飞轮壳加工工艺，包括：步骤一、加工飞轮壳的机体面一侧的孔系和面，步骤
