The advantage of CNC spinning machine is that the equipment and the die are relatively simple (no special spinning machine can be replaced by a lathe), in addition to forming such as cylindrical shape, cone, paraboloid formation or other forms of various curves of the rotation outside the body, but also can process relatively complex shape of rotating body parts. The disadvantage of traditional manual spinning is low productivity and high labor intensity. With the development of numerical control technology, new numerical control spinning has been very suitable for mass production.

Large CNC spinning machine is mainly used for spinning at both ends of cement tank truck and gasoline storage tank. Due to the relatively large volume and thick thickness, manual operation cannot be carried out. Generally, the machine is used for working.

The pressure inside the tank is increased, the strength of the tank and the sealing effect are increased. When large spinning did not enter industrial use, the way of welding was used. During the welding process, there were sand holes, and the liquid would flow out through the sand holes. Therefore, the welding requirements are very high, usually welding tank qualified rate is very low, quality is not good. After using the spinning head, the reduced welding area has a very good effect on improving the qualified rate of oil tank container.

CNC spinning machine

In recent years, the appearance of ultra-large spinning machines has been continuously emerging. For large containers, integrated spinning and forming can be realized, and manual welding process is completely eliminated. The qualification rate of large containers produced by spinning and production efficiency is about 10 times higher than that of welding.

The application range of spinning process is very wide, which cannot be separated from its advantages, so this spinning process highlights this advantage. Here is a simple illustration from hongxiang CNC spinning machine:

1. The metal deformation condition is good. The metal contact point near the contact point of spinning and spinning is small.

2. There are a wide range of products. According to the capacity of the spinning machine, large diameter thin-walled pipe, special pipe, variable section pipe and spherical and semi-spherical pipe can be produced.

3. High material utilization and low production cost.

4. Low surface roughness and small size tolerance.

5. The hollow part of the whole seamless rotary body can be made to fundamentally eliminate discontinuities related to welding seams, reduce strength, embrittlement and stress concentration.
