CDC-S series CNC spinning machine is a special equipment for producing spinning pulleys. As a new technology product, spinning pulley has been widely used in automobile engines, such as motor wheel, water pump wheel, power steering pump wheel, air conditioning wheel, fan wheel and so on. According to the groove type and processing technology of pulley, it can be divided into three categories: split pulley, folding pulley and multi-wedge pulley. Because of the different structural characteristics of these three spinning pulleys, their processing technology is also different.

The thickness of the material selected for the multi-wedge wheel is 2 ~ 6mm, generally 3mm. The blank is made by drawing and stamping, and processed and formed on the spinning machine. Because the tooth profile is formed by metal flow and plastic deformation of material wall thickness, there are many factors that affect the final quality of products, including upper and lower dies, wheels, process parameters, materials and so on. It will be introduced in detail in the process analysis and mold design in the future.

The thickness of the folding wheel is 1.5 ~ 2.5 mm, and the blank is also made by drawing and stamping, and processed and formed on the spinning machine. Because there is no metal flow in the forming process of the folding wheel, the process is relatively simple and there are not many factors affecting the quality.

The material thickness of the distributor wheel is generally 4mm, which is usually a one-time blanking, and it is divided from half of the material thickness by the rotating wheel on the spinning machine and shaped. Because of its simple processing technology, there are not many factors affecting the quality, and the most important thing is the flatness of the blank itself. Therefore, the requirements for blanking dies are higher.
