Grinding surface quality of steel pipe is good
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.
Grinding steel cutting margin less
In order to achieve the precision required by the drawing, honing is the least processing method to eliminate the allowance in all the machining methods. In honing process, the honing tool uses the workpiece as the guide to remove the excess allowance of the workpiece to achieve the required precision of the workpiece. Honing, honing tools honing the workpiece to the largest margin, and then gradually honing to remove the minimum margin of place.
