JIS STKM 13C/ ASTM A106/ SAE 1020/ DIN ST 52 Welded Honing Cylinder Tubes manufacturer in India


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.

Honing Cylinder Tubes

 

There are numerous examples of hones, although all these examples consist of either one or more abrasive stones that are held under pressure against the surface of the Honing Cylinder Tubes they are worked upon.

However, there is an improvement also noted on the surface of these Honed Tubes. Because honing is an expensive process, honing is performed on Hydraulic Honed Tubes which require the most superlative degree of precision. One of the main benefits of using Bright Finish Seamless Honed Tubes is that they are precise and have an accurate form, with a smoother inner surface.
