 ID Honing

Utilize an abrasive stone,which turns while being moved in and out of the work piece.     

The honing process makes :

1.Smooth surface finishes inside bores     

2.Hold precise tolerances on bore diameters 

 ID: H7 H8 H9   ID roughness:0.2-0.8μm

Roller Burnish+ Skiving

Two thin chips are cut at high feed rate while the tool passes through the work piece. producing super finish surface,with a bore precise tolerance.

Advantages of Our 4140 hydraulic cylinder barrel

1.High precision tolerances;

Our honed tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension.

2.Seamless tube with high pressure resistance;We only use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications.

3.High Smooth inside surface;

The roughness of our honed pipe is Max Ra 0.4 microns ID finish (16Max Ra ID Finish).

Flexible order quantity: we accept small quantity orders, even if there is only one piece of hydraulic cylinder tubing we can produce and supply.

4.Good weld ability: The weld ability of our honed steel tubing is very good, this is quite helpful for manufacturing the cylinders.
