1, plasma cutting? Automatic plasma cutting machine is fast, but it is very troublesome to clean up because of a large amount of molten and cooled metal residues attached to the inner wall. Most plasma cutting will generate heat, so the pipe end will definitely change color, and the parameters are difficult to adjust. Improper use can easily lead to poor incision quality. At present, few users use plasma cutting machine to cut thin-walled stainless steel pipes. ?

2. The automatic barrel cutting tool has only one circumferential cutting edge and no serrations. Feed inward while rotating, the incision is smooth and smooth, without iron filings and burrs, and the inner wall is slightly narrowed. Coupled with special tooling, it can greatly improve the closing phenomenon, and the equipment cost is low, which is the most suitable choice for small and medium-sized enterprises. When cutting the stainless steel pipe with a wall thickness of 0.3 mm, it will tear at the moment of being cut off, and the nozzle will be seriously deformed. When cutting large-diameter thin-walled stainless steel pipes, it is necessary to add special devices to realize cutting without deformation, which has high technical requirements for operators.

3. For cutting very thin-walled stainless steel pipes (with a wall thickness of 0.2 ~ 0.6 mm and a diameter range below 32 mm), the instrument lathe is recommended to use high-quality Bai Gang or Fenggang tools. The cutter is low in cost, durable and smooth in cutting surface, and is suitable for cutting household products such as mop tubes, broom tubes and mosquito net tubes. This method has low automation and high labor intensity. Suitable for cutting small diameter round tubes. At present, the cutting efficiency of automatic instrument cutting machine and pipeline cutting machine will be greatly improved, and the labor intensity of operators will also be reduced.

4. In addition, there is a similar automatic instrument lathe, which only rotates the feed tool without moving the pipe, thus solving the inconvenience caused by the rotation of the super-long steel pipe. You can use two knives to cut at the same time, so that one knife can cut off and the other knife can correct the cross section of the steel pipe, but this cutting method is only suitable for small batch cutting. ?

5. Saw blade cutting. At present, the saw blade used to cut thin-walled stainless steel pipes generally adopts tungsten steel saw blade cutting, combined with the automatic feeding system set by numerical control, which has high automation, simple operation and low labor intensity. One person can operate multiple machines at the same time. When cutting thin-walled stainless steel pipes, the cutting speed is fast, the incision is not deformed and burr-free, and the cutting accuracy is high. Field test cutting 19*0.3*200mm pipe fittings, each
