Process nature of honing tube

- Jul 29, 2020-

The honing pipe is processed by rolling, because the surface layer has residual compressive stress on the surface, which helps to close the micro-cracks on the surface and hinder the expansion of erosion. Thereby improving the corrosion resistance of the surface, and can delay the occurrence or expansion of fatigue cracks, thus improving the fatigue strength of the honing tube. Through roll forming, a cold-work hardened layer is formed on the surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the honing tube and avoiding burns caused by grinding. After rolling, the surface roughness value decreases, which can improve the matching properties.
