CNC Metal spinning characteristics

Compared with CNC Metal spinning, manual spinning technology is limited by manpower and cannot process spinning products with larger thicknesses. When stamping and deep drawing process metal forming products of the same thickness, the required processing force is 3% of spinning. -5 times, so stretch stamping requires a large tonnage punch or hydraulic press to process aluminum with a thickness of 4mm or more, Stainless steel with a thickness of 2mm, and iron with a thickness of 3mm. After mass production of the product, the forming speed of stretch stamping will be faster than that of CNC Metal spinning, and the unit cost will be lower. For products with larger stretch lengths, stretch stamping is prone to cracking, while Metal spinning takes a longer time to form a single product. Typically, Metal spinning is used to make semi-finished blanks and then Metal spinning is used to make the final product. The combination of the two processes can greatly improve the production efficiency of the product and reduce the reject rate of the product. Aluminum/Alloy Products and Iron/Galvanized Products are easy to combine spinning and drawing. Due to the high hardness of stainless steel, the stretched billet is prone to cracks at the spinning joint.

2 . CNC spinning machine idling accuracy is 0.04mm. Due to the influence of material flow and stress rebound during the spinning process, the precision of the processed product cannot reach 0.04mm. Among the three materials of aluminum, iron and stainless steel, the accuracy of Stainless steel Metal spinning is the most difficult to control. Taking the diameter of 100mm as the benchmark, the diameter accuracy of general aluminum spinning parts can reach 0.1mm, and the diameter of iron is about 0.2mm. , the diameter accuracy of Stainless steel is about 0.4mm. The larger the product diameter, the worse the accuracy. Strong rotation is more accurate than normal rotation. When the spinning parts have assembly accuracy requirements, they can be finished. At present, the product series widely used in CNC Metal spinning include Lamp Shade , Stainless steel bowl, Lighting Downlight, Aluminum Cup, Reflector Shade, shielding cover, signal reflector, signal receiving cover, chemical container, power container, aluminum barrel, stainless steel barrel, Ventilation ducts, funnels, electrical liner, motor protective cover, etc. CNC Metal spinning process is more suitable for such special customized, small and medium batch processing products.
