Honing tube

The processing of honed tubes is rolling processing, and the surface of the steel pipe is under pressure. It has a good sealing effect on small surface cracks and can prevent surface erosion. Therefore, it can improve the surface's corrosion resistance, reduce the occurrence and expansion of cracks, thereby increasing the compressive strength of the honed tube. The difference between honing and internal grinding is that the honing head is inserted into the hole, and then driven by the machine tool to rotate and reciprocate, raising the grinding rod for cutting. Honing machines can be divided into vertical and horizontal types. The vertical type is more suitable for continuous production of a large number of shorter parts, such as cylinder liners, while the horizontal type is more suitable for producing longer parts. If it is used to process cast iron, the production efficiency is several times higher than that of internal grinding. However, the honing efficiency of steel parts is worse than that of cast iron, but it is much faster than internal grinding, and precision is not a problem.

To improve the accuracy of honed tubes, the following aspects can be considered:

1. Improve surface roughness.

2. Correct roundness.

3. Increase surface hardness, reduce stress and deformation.

4. The residual stress layer after processing can increase fatigue strength by 30%.

5. Strengthen matching quality, reduce wear, and improve the service life of parts, while reducing processing costs.
