Analyze the superiority of CNC spinning machine

CNC spinning machine origin and origin flow manual technology, according to some, can be traced back to China in the 10th century. Today, it is a powerful and advanced manufacturing process for CNC machine tools. Today, the industrial textile industry is not only formed using precision metal spinning, also known as flow-related processes. In fact, flow formation can be considered a special spinning process.

From the perspective of economics, the main advantage of CNC spinning is that the cost is reduced near the whole line, from the processing cost, trial production, and initial investment, to the overall energy efficiency and process secondary operations.

From the point of view of the strength of the part, the details of the CNC spinning process, with a part of the stamping, result in a lower toughness strength and a lower chance of crack propagation in the finished piece if a defect does occur.

From the versatility of the shape, for non-uniform hollow shapes, such as concave or convex parts, elliptical shapes or cones, the numerically controlled spinning exceeds the clear answer of deep drawing.

The CNC spinning machine can perform various tasks such as deep drawing, ribbing, closing, sealing, flanging, and crimping. Due to the spin forming process, the universally-pressed workpieces have various shapes and thus have a wide range of uses. The CNC spin forming process has shrinkage, expansion, and curling.

The numerical control spinning machine needs to understand the deep drawing, the expanding and pressing ribs, the shrinking and closing, and the curl forming. In these kinds of forming, the ordinary spinning can satisfy the integral forming and the partial forming. On the modern spinning machine, for different technical requirements of different specifications of workpieces, cold spinning and hot spinning can be used to carry out corresponding plastic forming. The main categories are drawing, shrinking, expanding, and stemming.

1, the metal deformation conditions are good, the rotating wheel and the metal are point contact, the contact area is small, the unit pressure is high, up to 2500~3500Mpa. Suitable for processing materials with high strength and difficult deformation. When the same workpiece is machined, the spinning is about 1/20 of the power consumed by the stamping.

2, a wide range of products, all workpieces with rotary work can be used in the spinning process. Such as: LED light cups, reflective cups, lighting accessories, car exhaust pipes, rice cookers and other small home industries.

3. High material utilization rate and low production cost. Compared with machining, spinning can save about 70% of materials. The quality of the workpiece is high, and the microstructure of the material changes after spinning, and the grain of the material has fibrous characteristics. Tensile strength and hardness are improved. The surface of the product has low surface roughness and small dimensional tolerance. The reach tolerance is 0.05mm.

4, the workpiece is seamless, eliminating the welding-related discontinuities. Compared with stamping, the spinning process is simple, the spinning is completed once, and the punching requires multiple stretching. The material is widely available and can be spun by various materials such as aluminum, copper, stainless steel, iron and aluminum alloy.
