Automatic spinning machine is the main equipment of metal spinning. In order to facilitate the smooth operation of metal spinning process, many supporting equipment and devices are needed, such as melting furnace, casting device, turning machine, heat treatment furnace, combination fixture, shaping machine, etc. The main foreign production of automatic spinning machine countries are the United States and Germany. Germany used spinning technology in the civil industry earlier than the United States, the early manufacturing of automatic spinning machine is medium, small, in recent years also made large automatic spinning machine. Automatic spinning machine can be divided into horizontal and vertical type in structure. In China, horizontal automatic spinning machine has large rigidity and small floor area. As the vertical center line of the workpiece coincides with the center line of the machine tool's spindle, the precision of the product is higher.

In the application of numerical control technology, the automatic spinning machine can achieve the following effects to a certain extent, that is, shorten the preparation time and processing time, adapt to the change of processing conditions, improve the repeat processing accuracy and prevent accidents. However, some of the new hydraulic copying automatic spinning machine can also achieve. In addition, no matter which control method is adopted, the determination and output of the cycle path depends largely on the skilled skill of the operator. Therefore, the nc automatic programming technology will be an important research topic in the future. It should be able to determine and input the cycle times and produce qualified products only by input the shape, size and shape of the rotating wheel according to certain routine procedures.

The application of automatic spinning machine technology is more and more extensive, and the requirement for automatic spinning machine is higher and higher, especially for spinning equipment with large diameter, large thrust, high precision and high degree of automation. Foreign powerful spinning equipment has been serialized and is developing towards large scale, multi-purpose and high automation. With the development of computer technology, the control system of automatic spinning machine is developing. The screw feed has been fully developed to numerical control, the speed change of the spindle has been developed from step to step, and to the automatic spinning machine with multi-rotation frame. Television monitoring system and wall thickness ultrasonic automatic measuring device are also used in automatic spinning machine.

Proper heat treatment can refine the internal grain of the metal, change the metal crystal structure and thus change the metal properties. Therefore, people begin to combine heat treatment technology with spinning technology to create a new spinning process, which has laid a new milestone for spinning technology. In recent years, many scholars have done a lot of research on the combination of heat treatment and spinning. Although the above research has provided theoretical support and practical guidance for the application of aluminum alloy spinning technology in industrial production, with the development of industrial production, in order to meet the demand, the author thinks that it will have epoch-making significance if aluminum alloy spinning technology develops from the beginning to the end. With the development of science and technology, the requirement of automatic spinning machine is higher and higher. Due to machining hardening and other defects in the process of cold spinning, the technology of cold spinning can no longer meet the demand of production.
