There are several advantages to pneumatic honed tube:

- Sep 01, 2019-

1. Improve the surface roughness, and the roughness can reach Ra≤0.08μm.


2. Correct the roundness, the ellipticity can be ≤0.01mm.


3, improve the surface hardness, so that the deformation of the force is eliminated, the hardness is increased by HV ≥ 4 °


4. There is residual stress layer after processing to increase fatigue strength by 30%.


5, improve the quality of the coordination, reduce wear and extend the life of the parts, but the processing costs of the parts are reduced.
