Deburring,descaling, degreasing of stainless steel welded pipe, tube cutting parts, mirror polishing technology
How to remove burrs, oxide scale, degrease and mirror polish stainless steel welded pipe cutting parts?
Stainless steel pipes, tubes can be divided into stainless steel seamless pipes and welded pipes according to the production process. Seamless pipes are produced by perforating, drawing and rolling steel bars, while welded pipes are produced by rolling and welding steel plates. In terms of compressive strength, seamless pipes are better than welded pipes, but the advantages of welded pipes are low cost, simple process and high production efficiency. Today we will share a case of mirror finishing and polishing of a small round tube after sawing from a 304 stainless steel welded pipe, tube. This polishing process solution is also suitable for other hardware parts made of materials such as 201, 316, 321 or nickel-titanium alloys, which require deburring, deflashing, descaling and mirror polishing after sawing, plasma, water jet, electric spark and other cutting processes.

5. Additional instructions
- This stainless steel welded pipe, tube cutting hardware parts product is a small product made by sawing the welded tube. There are obvious burrs on both ends of the pipe, tube, but the tube wall is thin, which can easily cause deformation of the workpiece during polishing. Therefore, the rough finishing and polishing machine uses a vibratory bowl polishing machine with moderate finishing force and high cutting efficiency. The rough finishing uses heavy-cutting spherical ceramic deburring media, which can quickly remove burrs, scales and oil stains.
- Fine finishing uses precision finishing media with light cutting force and small abrasive grain size to further reduce surface roughness.
- The last step after fine finishing is to use a mirror polisher and mirror polishing media to enhance the brightness and mirror polishing.
6. Final summary
- In this case, we demonstrated the process of automated deburring, degreasing, mirror polishing of the outer surface of a 304 stainless steel welded pipe, tube cutting hardware part.
