When any machine is processing parts, it may be affected by itself or the
surrounding environment, which will cause the final precision of the product to vary. What are the factors introduced by CNC Metal Spinning Machine Manufacturer today that will affect the accuracy of CNC spinning?
Metal Spinning Machine
Although CNC spinning is controlled by a CNC system to control the spinning wheel extrusion molding, the final accuracy of spinning molding is not very close to the accuracy of CNC lathes recognized by the public, because the material's stress rebound performance will affect the accuracy of the product. The precision of pressed products is much lower than that of turned products. In addition, most CNC spinning machines have spinning and turning functions, but the precision of turning on CNC spinning machines cannot reach the precision of lathe processing molds, because spinning products are thin-walled parts, which will appear during the turning process. Deformation causes the phenomenon of knife and vibration, so the actual accuracy of CNC spinning products after turning is not as high as that of traditional turning parts.
Compared with CNC spinning and stamping and drawing, the accuracy of CNC spinning is usually lower than that of precision stretching. However, when the thickness of the material is relatively low, the strength and hardness of the stretched stamped parts are not enough. Deformation is easy to occur, and the accuracy of stretching and pressing will be worse than that of spinning.
The precision of CNC spinning products will be higher than that of manual spinning. Because the manual control force in each spinning process cannot be consistent, dimensional stability is poor.
Advantages of metal spinning
There are many advantages to Metal Spinning Machine, which are not available in mechanical processing, especially suitable for some high-strength and difficult-to-deform materials, which can be turned to spinning.
The metal has good deformation conditions. Because the spinning wheel is in almost point contact with the metal during spinning, the contact area is small and the unit pressure is high, which can reach 2500 ~ 3500MPa. Therefore, spinning is suitable for processing high-strength materials that are difficult to deform. Moreover, the required total deformation force is small, so that the attack rate consumption is greatly reduced. For processing the same size parts, the tonnage of the spinning machine is only about 1/20 of the tonnage of the press. The metal spinning material has a high utilization rate and low production cost. Compared with machining, spinning can save a lot of materials, and we are serious about reducing costs.
