Across several industries, a hydraulic cylinder tube is referred to as a Honed tube. One of the most important materials of manufacturing hydraulic cylinders are Honed Tubes. This type of tubing is ordinarily honed in the inside diameter of a Ready to Honed Tube. Which is why it is also known as honed ID tubing. Honing is an abrasive or a grinding machining process that delivers a precision surface on a metal workpiece for e.g. Hydraulic Tubes. During this process, an abrasive grinding stone or grinding wheel is scrubbed against a Pre Honed Tube along a hegemonized path. Honing is a process which is fundamentally used to enhance the geometric form of a surface.

ASTM A519 Standard Specification for Seamless Carbon and Alloy Steel Mechanical Tubing
