When the spinning parts have assembly accuracy requirements, they can be processed by finishing. At present, the products widely used in CNC Metal Spinning Machine include lampshade, stainless steel bowl, stainless steel pot, shielding cover, signal reflector, signal receiver cover, chemical container, power container, aluminum barrel, stainless steel barrel, venturi, fan outlet , ventilation ducts, funnels, electrical liner, motor protective cover, etc. The CNC spinning process is more suitable for such special customized, small and medium batch processing products.
The motion principle of CNC spinning and manual spinning is the same in the product forming process. The clamping force is provided by the tail top to drive the material to rotate with the main shaft. The cutter wheel makes the material from point to line according to the predetermined tool path. Line-to-surface extension, post-molding. The difference is that the CNC Metal Spinning Machine controls the path of the cutter wheel during the spinning process and the gap between the cutter wheel and the mold. Due to the high running accuracy of CNC machine tools, good equipment rigidity, and large processing force, the manufactured products are consistent, stable in production, and can control the accuracy of the products well; while manual spinning is in the process of spinning, by manual Control the tool holder to determine the tool path of the cutter wheel, and the tool path and gap between each product are different, resulting in unstable product accuracy in batches.
When the thickness of the spinning sheet exceeds a certain range (iron exceeds 1.2mm, aluminum exceeds 1.5mm, and stainless steel exceeds 1mm), the artificial force cannot support the processing force required for spinning, and it is easy to cause the product to be scrapped. However, when manual spinning is used to make thin aluminum and iron products, the surface of the outer wall of the processed product will be better than that of CNC Metal Spinning Machine. However, after the continuous improvement of process technology in CNC spinning in recent years, the surface of the outer wall of the spinning product has been very similar to that of manual spinning.
