Product Description
Honed Tube is ready to use for hydraulic cylinder applications without further ID processing.
The honing process involves using abrasive polishing stones and abrasive paper to remove small amounts of material, to produce extremely precise ID dimensions and improved finishes. Honed tubing is ready to use for hydraulic cylinder applications without further ID processing.
Skived rolling burnished pipes refers to a kind of pipe manufactured by skiving and rolling processing technology. Rolling is a common metalworking method that can be used to manufacture tubular products of different shapes and sizes, including tubes, pipes, steel pipes, etc.
Honing is a kind of machining technology. Through honing head, the inner hole of cold drawn pipe is processed by reciprocating high-speed grinding technology, so that the inner hole can meet the requirements of tolerance size and surface roughness that we need.
Honed tube is a kind of smooth bore steel tube used to manufacture hydraulic cylinder barrels that is the core part of a piece of hydraulic cylinder.
Difference between honed tube and skived & roller burnished tube: In hydraulic cylinder industry, there are 2 solutions for bore treatment: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing leads to different internal surface image, but both ensure good roughness.
