What should be paid attention to when stainless steel spinning processing operation

Stainless steel is a commonly used metal spinning material. Compared with aluminum and iron, the spinning process of stainless steel is more difficult. In the spinning production process, the following issues need to be paid attention to.

1. The cutter wheel needs hard materials

The general spinning cutter wheel is made of CR12 steel, but spinning stainless steel, CR12 steel is not hard enough, the cutter wheel is easily scratched by the stainless steel material, and there will be a lot of scratches on the surface of the final formed product. CR12 can be used for electroplating or change to high-speed steel material, the cutter wheel is not easy to wear.

2. The surface of the blank needs to be brushed with drawing oil

During the process of stainless steel spinning, the temperature of the material, mold, and cutter wheel is very high, so it is necessary to continuously coat the surface of the material and the mold with drawing oil. The drawing oil has a lubricating effect and adheres to the drawing of the surface of the material. Oil also has a cooling effect. If the spinning stainless steel is not coated with stretching oil, the product will be easy to crack or be scratched by the cutter wheel. In addition, there is no stretching oil effect. After the cutter wheel is produced for a long time and the mold is heated up, the gap will become smaller, causing machine vibration and spinning. The surface texture of the product is uneven.

3. The gap between the spinning cutter wheel and the mold

The temperature rise of the spinning process for a long time causes the gap between the cutter wheel and the mold to become smaller. It is necessary to adjust the gap between the cutter wheel and the mold in time. The thickness of the stainless steel material is about the thicker, the more obvious the temperature rise during the processing.

4. Cutting blade wear

After the stainless steel spinning is completed, it is often necessary to trim the edges. The trimming is performed with turning cutter blades. Due to the high hardness of stainless steel materials, the blades are easy to wear. After the blades are worn, there will be many burrs on the stainless steel cutting edges, so you need to pay attention to it during production. Whether the stainless steel blades are worn or chipped, the blades need to be replaced in time.
