Integrated precision forming processing method for large-size pure aluminum material metal diaphragm

The invention relates to an integrated precision forming machining method for a large-size pure aluminum material metal diaphragm, and belongs to the field of precision forming. A spinning-turning-cutting composite integrated precise forming process method is selected, one-time clamping of a product is achieved through a spinning and turning-cutting machining alternate forming mode, machining of all profiles and sizes is completed, machining stress is eliminated through heat treatment after machining, and precise forming machining of the metal diaphragm is achieved. The method can be widely applied to integrated forming machining of the pure aluminum (aluminum alloy) metal diaphragm, precise forming machining and uniform structure of the large-size pure aluminum material metal diaphragm are achieved, and it is guaranteed that the large-size pure aluminum material metal diaphragm is free of failure faults such as wrinkles, eccentricity and cracking in the overturning process. 本发明涉及一种大尺寸纯铝材料金属隔膜一体化精密成形加工方法，属于精密
