Nowadays, most companies in the spinning industry have already configured CNC spinning machines. Why are CNC spinning opportunities so popular? This is mainly because this equipment has the unique advantages of other spinning processing methods.
When using CNC spinning, the metal shape condition is better than other spinning methods, because the spinning wheel of the CNC spinning machine is in point contact with the metal, and the contact area and unit pressure are as high as 2500~3500Mpa or more. CNC machining the same workpiece is about 1/20 of the power consumed by stamping, so it is suitable for machining high-strength materials that are difficult to deform. The CNC spinning machine can have a wide range of products, and all the workpieces with rotation can use the spinning process. For example: LED lamp cups, reflectors, lighting accessories, automobile exhaust pipes, rice cookers and other small homeware industries. And the whole workpiece is seamless, which eliminates the discontinuity related to welding.
Compared with stamping, spinning process is simple, spinning is completed at one time, stamping requires multiple stretching. It can be used for spinning aluminum, copper, stainless steel, iron, aluminum alloy and other materials, and the source of materials is quite wide. Compared with machining, spinning has a very high utilization rate of materials, which can save about 70% of materials, greatly reducing production costs. The surface roughness of the spinning products is low, and the dimensional tolerance is small. The reachable tolerance is 0.05mm. The quality of the workpiece is also very high. After spinning, the structure of the material changes, and the material crystal grains have fibrous characteristics. The tensile strength and hardness are improved.
