Kaden, a hydraulic valve purchaser from the United States, has been successfully purchasing hydraulic valves from China in recent years, and his boss also attaches great importance to him. Last month, at the original hydraulic valve manufacturer, he placed an order for a hydraulic valve block with multi-stage valve spool hole. The manufacturer confirmed that there was no problem and submitted the PPS of hydraulic valve block for 3 times, but the accuracy of valve spool hole was not approved every time. This made his customer very unhappy and thought it was a waste of his time. If the 4th hydraulic valve block sample still could not be approved, the order would have to be cancelled.

Kaden realized that the current hydraulic valve manufacturer must be replaced and contacted with no less than 10 hydraulic valve manufacturers. No factory has the ability to accept the order of this hydraulic valve block. Because the valve spool hole of this hydraulic valve block had a multi-stage structure, the accuracy was difficult to be controlled, the diameter tolerance of the valve spool hole of the hydraulic valve block was small, and there were many accuracy requirements such as coaxiality.

Kaden was a little frustrated and seemed to have to give up. A hydraulic valve manufacturer in Ningbo told Kaden that the multi-stage valve spool hole must be processed with URMA reaming technology, and AAK hydraulic valve had this technology and could have a try.

AAK hydraulic valve URMA reaming technology adopts guide bar support to ensure correct tool position and rigorous cooling to ensure tool lubrication. Especially for multi-stage valve spool hole, or valve spool hole with small diameter, we have our own processing experience. This is rare in Ningbo hydraulic valve manufacturers. Many times, some peers admire and spontaneously recommend those hydraulic valve customers with this special requirement to us.
