Repair method for deformation of friction pair in rotary joints

The lifespan of a rotary joint is generally one or two years, and it is inevitable to have problems. Timely maintenance or correction can continue to be used without replacing the joint, which not only wastes money but also time. The longest encountered deformation is the sealing pair, which needs to be corrected to ensure the flatness of the conflicting pair
