If you want to improve the precision of the honing tube, you can start from the following aspects:
1. Improve surface roughness.
2. Correct roundness.
3. Improve 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 the fit, reduce wear and increase the service life of the parts, but the processing cost of the parts is reduced instead.
