Carbon Steel Pipe Hydraulic Cylinder Special Honing Pipe, Hydraulic Cylinder Boring Grinder S Hydraulic Steel Pipe
Product description
Honing the cylinder pipe
The surface quality is good, the surface is cross mesh, which is conducive to the storage of lubricating oil and the maintenance of oil film. It has a higher surface support ratio (the actual contact area of the hole and the shaft and the ratio of the matching area between the two), so it can bear larger load and wear resistance, thus improving the service life of the product.

Product advantage
Honing Process is a special form of grinding, which is an efficient method of addition and precision. This process can not only remove large machining allowance, but also is an effective machining method to improve the dimensional accuracy, geometric accuracy and surface roughness of parts. It is widely used in the manufacturing of automobile parts.
Product application
Honed tubes are widely used in hydraulic cylinders, cylinders, hydraulic machinery, engineering machinery, petroleum machinery, agricultural machinery, filling machinery, mining machinery and other fields.
