The application of CNC technology in hydroforming machines can effectively achieve the following results: reduced preparation and processing time, adaptability to changing processing conditions, improved precision in repetitive processing, and the prevention of accidents. However, certain aspects can also be fully achieved by some new hydraulic contouring automatic hydroforming machines. Moreover, regardless of the control method used in CNC hydroforming machines, the determination and placement of mandrel passes largely rely on the operator's skill. Therefore, CNC automatic programming technology will be an important research topic in the future. It should be able to input the shape, dimensions of the workpiece, and the shape of the mandrel through a set of routine procedures, thereby determining and inputting the mandrel passes and producing qualified products.
Proper heat treatment can refine the internal grain structure of metals and alter the crystal phase organization, thereby modifying the metal's properties. As a result, there has been a growing trend to combine heat treatment technology with spinning technology, creating new spinning processing methods and establishing a new milestone for spinning technology. In recent years, many scholars have conducted extensive research on the integration of heat treatment and spinning processing. Although the aforementioned research has provided theoretical support and practical guidance for the application of aluminum alloy spinning technology in industrial production, the author believes that if this technology evolves in the following directions, it will have epoch-making significance. With the advancement of technology, the requirements for spinning equipment products are also increasing. Due to the processing hardening and other defects that occur during cold spinning, this technology is no longer sufficient to meet production demands.
The spinning forming technology is a plastic forming process in which a blank is rotated by a spindle, with the core mold and top block fixed, and then advanced axially and radially by the spinning wheel. Local continuous deformation of the blank is achieved through the compression of the core mold and the spinning wheel. This spinning forming technique combines the advantages of rotational forming and plastic molding processes, offering high material utilization, rapid forming, excellent surface quality, high precision, and a variety of products. As a result, it holds a significant position in the fields of metal precision processing, such as aviation, aerospace, and weaponry, and has also found extensive application in the petrochemical, automotive manufacturing, electronics, and light industries.
