Honed tube is ready to use for hydraulic cylinder applications without further ID processing.
Honed tubes are precision tubes that have been processed to achieve a smooth inner bore and precise internal dimensions. They are commonly used in hydraulic and pneumatic cylinder applications where a high degree of accuracy and surface finish is required.
Honed tube is usually a CDS (Cold drawn seamless) steel tube or DOM (Drawn Over Mandrel) steel tube with inside diameter honed or skived &roller burnished, so honed tubing is with extremely precise ID dimensions and smoothly ID surface.
Honed tubes are broadly utilized to produce and repair hydraulic cylinders and pneumatic cylinders. So in many fields, the honed tube is called cylinder tube also.
Honed tube usually is produced by two main manufacturing process, which are honing process or skiving & roller burnishing process. The mother tube we usually use “Suitable To Hone” Cold Drawn Seamless Tubes. The process of the honed pipe is determined upon the dimension, mold available and the requirement of the customer.
As the leading hydraulic cylinder honed tube suppliers, most of the factories can produce honed cylinder tubes in a wide range of metric sizes and imperial sizes. Here below is the typical size range of honed tubes.
Inside Diameter 32mm to 600mm; Imperial sizes equally.
Normally honed tubing is supplied in fixed length or random lengths, the max. Length of honed tube is 14 meters, sometimes even longer for special application purpose.
The specific size of a hone tube can vary depending on its application and the requirements of the user. Common sizes for hone tubes can range from small diameters like 1 inch (25.4 millimeters) to much larger diameters exceeding 10 inches (254 millimeters). The precise size you need would depend on the intended use, such as hydraulic cylinders or pneumatic systems, and the tolerances required for your application.
The tube size e quality of steel required for the project were not standard, so it had been necessary not only to manufacture the tube on customer’s specification, starting from a specific raw material tube but also to plan a peculiar manufacturing process.
For example, also both left ends had been treated in order to let the assembly of the piece. It has to be stressed the importance of honing the left ends and the roundesses where the O-Ring is allocated since they impact dramatically on the system performance.
Honed tubes are used in a variety of industrial applications, primarily in hydraulic and pneumatic systems. Here are some common uses of honed tubes:

Honed tubes are an essential component in many industrial applications where precision and performance are critical. Their smooth inner surface and precise dimensions make them ideal for use in hydraulic and pneumatic cylinders, as well as other engineering applications where high-quality tube performance is required.
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.
Honed tube is well known as the best material to manufacture hydraulic cylinders. This is because honed tubes are the most critical materials for hydraulic cylinders. Honing is essentially a bore sizing and surface preparation process.
The tubes surface finishing is NBK, where the tubes are phosphate and normalized which provides corrosion resistance. It is oiled inside and outside. Normalize process creates tougher metal product. During normalizing, metals will be heated at a high temperature, and it allowed to naturally cool back down to room temperature by exposure after heating. Metals that have been through this process are more formable, harder and ductile.
The honing process is a form of grinding and a processing method in finishing. Not only with high productivity, but also with high machining accuracy, the function is to improve the surface finish and wear resistance of the honed tubes.
Step 1. Raw Material selection:

Step 6. Honing on the tube inner diameter
The ID (inner diameter) of the tube is honed with honing stone, so that the through inner diameter of the tube can meet the size and machining accuracy requirements of seamless honed tubes;
Step 7. Inspection and packing:
Inspect the finished honed tubes according to customers’ requirements and corresponding standards, to ensure they can meet the required size and machining accuracy requirements, mechanical properties, chemical compostions, etc.
