Sales Hotline: 15206508233 1, improve the surface roughness, roughness can reach RA or 0.08µ m.

The 2 amendment, roundness, ovality can be less than 0.01mm.
3, improve the surface hardness, the deformation is eliminated, the hardness increased more than 4 DEG HV
4, residual stress layer after processing, improve fatigue strength increased by 30%.
5, improve the quality of cooperation, reduce wear and tear, prolong the service life of parts, but the processing cost of parts is reduced.
Precision grinding tube surface quality
The surface is crossed reticulate, which is beneficial to the storage of lubricating oil and the retention of oil film. It has higher surface supporting ratio (the ratio between the actual contact area of the hole and the shaft and the matching area between the two holes), so it can bear greater load and wear resistance, thus improving the service life of the product. Honing speed is low (is one of the dozens of grinding speed), and the whetstone and the hole is surface contact, so the average grinding pressure of each abrasive particle is small, so honing, the workpiece heating is very small, the workpiece surface almost no thermal damage and metamorphic layer, deformation is small. There is almost no sand and extrusion hard layer on honing surface.
