The Precautions for CNC Metal Spinning Machine in the Process of Processing Stainless Steel Products

During the spinning production process, the following four issues need to be taken into account.

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

The temperature rise in the long-term spinning process 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 thicker stainless steel material, the more obvious the temperature rise in the processing process.

2. Cutting grain wear

After the stainless steel spinning is completed, it is often necessary to trim the edge. The edge trimming is turned with a turning knife grain. Due to the high hardness of the stainless steel material, the knife grain is easy to wear. After the knife grain is worn, many burrs will appear on the stainless steel trimming edge, so attention should be paid Whether the stainless steel knife grains are worn or broken, the knife grains need to be replaced in time.

3. The cutter wheel needs hard material

Generally, CR12 steel is used as the material for spinning knife wheel, but the hardness of CR12 steel is not enough for spinning stainless steel, the knife wheel is easy to be scratched by stainless steel material, and there will be many scratches on the surface of the final formed product. CR12 can be used for electroplating or high-speed steel material, and the cutter wheel is not easy to wear. Stainless steel is a commonly used metal spinning material. Compared with aluminum and iron, the spinning process of stainless steel is more difficult.

4. The surface of the sheet needs to be brushed with stretching oil

In the process of professional stainless steel spinning, the temperature of the sheet, mold and cutter wheel is very high, so it is necessary to continuously apply stretching oil on the surface of the sheet and the mold. In addition to the lubricating effect of the stretching oil, Stretching oil also has a cooling effect. If the spinning stainless steel is not coated with stretching oil, the product is easy to crack or be scratched by the cutter wheel. In addition, without the effect of stretching oil, the gap will become smaller after the cutter wheel is produced for a long time and the mold is heated up, causing machine vibration and spinning The surface texture of the product is uneven.
