Honed tubing is seamless cold drawn steel tubing that have been honed. Honing is a machining process. The inner hole of the cold-drawn steel tube is reciprocating high-speed grinding through the honing head, so that the inner hole can meet the required tolerance size and surface roughness requirements for the hydraulic cylinder barrels.
Compared with the traditional honing process, the boring and rolling tube has the following advantages:
1. Improve processing efficiency: the processing speed is nearly twenty times that of honing
2. Improve the surface hardness: the surface hardness is increased by more than 50%.
3. Machining accuracy: The machining accuracy can reach IT8 level, and the surface roughness can reach Ra0.05-0.4μm
4. Working environment: low noise, no pollution, saving labor costs
5. Reasonable processing procedures: Scraping and rolling can be arranged as the last procedure after other procedures (such as drilling holes, welding, threading, etc.) are completed.
Both honed tubes and bored&rolled tubes can be used as hydraulic cylinder barrel of hydraulic cylinders.
