How to remove burrs, descale, rust, mirror polish the copper pipe fittings?
Copper (pure copper, brass, copper alloy) pipe, tube fittings deburring, descaling, mirror polishing technology method
Copper pipe, tube fittings, including copper, brass or other copper alloy pipe fittings, are generally used in plumbing systems and can also be used in food hygiene industries to inhibit bacterial growth. In order to improve the brightness of the product surface, the inner and outer surfaces need to be mirror polished. The traditional polishing process is to use a manual emery wheel for grinding. In this case, we will share a copper elbow pipe(tube) fitting product deburring, descaling, polishing and brightening process technology and methods. This finishing process solution is also suitable for deburring, descaling, chamfering and polishing of other materials such as brass, copper alloy, stainless steel, carbon steel and other pipe tube fittings.

5. Additional instructions
-
During the extrusion and stretching process of copper pipe fittings, the surface tensile lines and pits should not be too high or too deep. If the surface tensile lines and flash are too thick due to the mold, they need to be rough-grinded and leveled with a sanding machine first, and then put into the machine for finishing. In order to improve the batch processing capacity, the rough finishing and polishing machine adopts a vibratory bowl polishing machine, with the heavy-cutting spherical deburring ceramic tumbling media, which can achieve the effect of deburring and removing the oxide layer.
Using light-cutting precision finishing abrasive media, cone-shaped plastic media for fine finish to further reduce surface roughness. - After fine finishing, use a mirror polisher and mirror polishing abrasive media to enhance the brightness and mirror polishing.
6. Final summary
- In this case, we demonstrated the process of automated deburring, descaling and mirror polishing of the outer surface of a copper elbow pipe fitting.
