How to improve the precision of thick-walled honing pipes

       1. Increase the surface roughness of the honing tube.
       2. Correct roundness.
       3. Strengthen surface hardness and reduce stress deformation.
       4. There is a residual stress layer after processing, which can increase the fatigue strength by 30%.
       5. Strengthen the quality of fit, reduce wear, and increase the service life of components, but the processing cost of components will actually decrease.
