Skived & Roller Burnished Tube​

Skived & Roller Burnished Tube

Skived and Roller Burnished Tubes are precision-engineered tubes widely used in industries such as hydraulics, pneumatics, automotive, and aerospace. These tubes are known for their superior surface finish, dimensional accuracy, and durability. The manufacturing process involves two key steps:

1.Skiving:

Skiving is a machining process where the inner surface of the tube is cut to remove imperfections and create a smooth, uniform surface.

This step ensures the tube has a consistent inner diameter and prepares it for the next stage.

2.Roller Burnishing:

After skiving, the tube undergoes roller burnishing, where a hardened roller is pressed against the inner surface.

This process compresses the surface, improving its hardness, surface finish, and dimensional accuracy.

Roller burnishing also enhances the tube’s wear resistance and reduces friction, making it ideal for high-pressure applications.
