Several advantages of honed tube

1, improve the surface roughness, roughness can basically reach ra≤0.08μm around.

2, the correction roundness, the ellipse degree may ≤0.01mm.

3, improve the surface hardness, so that the force deformation elimination, the hardness increase hv≥4°

4, the residual stress layer after processing, improve the fatigue strength increased by 30%.

5, improve the quality of the match, reduce wear and prolong the service life of parts, but the cost of parts is reduced
