Stainless steel spinning is a commonly used metal material. Stainless steel is more difficult to spin than aluminum and iron. In the spinning production process, the following issues need to be noted. 1. The tool wheel needs a hard material CR12 steel is usually used as the material of the rotary cutting wheel, but the hardness of stainless steel spinning and CR12 steel is insufficient, the cutting wheel is easy to be scratched by the material, and the surface of the final molding product will appear a lot of scratches. CR12 can be used in electroplating or high-speed steel materials, and the cutter wheel is not easy to wear. 2. It is necessary to brush the stretching oil on the surface of the material. During the spinning process, the temperature of the billet, die and cutter wheel is very high, so it is necessary to continuously apply the stretching oil on the surface of the billet and die. In addition to having a lubricating effect, the stretching oil is also attached to the surface of the blank. The stretching oil also has a cooling effect. If the rotating metal is not coated with stretching oil, the product is easy to crack or be scratched by the knife wheel. In addition, in the absence of the role of stretching oil, after a long time of production cutting wheel and mold heating, the gap will become smaller, causing machine vibration. The surface texture of the spinning product is uneven.
