Analyze the role of rolling processing in honing tube forming
The honing tube is made by rolling processing, which proves the important role of this processing method.
PassedRollingThe surface layer of the processed honing pipe retains surface residual compressive stress, which can seal the micro-cracks on the surface and prevent the expansion of corrosion, thereby increasing the surface's corrosion resistance and reducing the occurrence or expansion of fatigue cracks, thus increasing the fatigue strength of the honing pipe.
After rolling, the surface roughness value of the pipe is reduced, which can increase the matching properties.
Therefore, this method can meet the two purposes of finishing and strengthening at the same time, which cannot be achieved by grinding, and can have an effect on the shaping of the honing tube.
