What factors affect the machining accuracy of CNC spinning

When any machine is processing parts, it may be affected by itself or the surrounding environment, resulting in deviations in the accuracy of the final finished product. What factors will be introduced to you today will affect the machining accuracy of CNC spinning.

Although CNC spinning is extruded by the spinning wheel controlled by the CNC system, the final accuracy of spinning is not very close to the accuracy of the commonly known CNC lathe, because the stress rebound performance of the material will affect the accuracy of the product, usually spinning The precision of pressed products is much lower than that of machined products. In addition, most CNC spinning machines have spinning and turning functions, but the precision of turning on the CNC spinning machine cannot reach the precision of the lathe processing mold, because the spinning products are thin-walled parts, which will appear during the turning process. Deformation makes the knife and the phenomenon of 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 forming, the accuracy of CNC spinning is usually lower than that of precision drawing. However, when the wall thickness of the material is relatively low, the tensile stamping parts are insufficient due to the strength and hardness of the mouth It is easy to deform, and the precision of drawing and stamping will be worse than that of spinning.

The accuracy of CNC spinning products is higher than that of manual spinning, because the manual control force in each spinning process cannot be consistent, so the dimensional stability is poor.
