The day before yesterday, Franco from Spain left a message on AAK website: Can you customize hydraulic cartridge directional control valves with high precision requirements for valve holes? I estimate that Franco encountered the problem of unstable valve hole accuracy when purchasing hydraulic directional control valves. The stable manufacturing quality of hydraulic cartridge valve manufacturers lies in the machining accuracy. Recently, hydraulic cartridge valve manufacturer AAK introduced the precision machining of valve cages and valve spools for hydraulic cartridge valves. Today, we will introduce the machining accuracy of valve holes. Some hydraulic cartridge valve manufacturers focus most of their energy on the accuracy of the valve spool and valve cage, often neglecting the accuracy of the valve hole. Some hydraulic power units with high requirements may sometimes experience equipment abnormalities due to unstable valve hole accuracy.
After communicating with Franco, it was learned that he encountered unstable valve hole accuracy in hydraulic directional control valves purchased from other hydraulic cartridge valve manufacturers. He was unable to investigate the accuracy of each valve hole, and the original manufacturer could not guarantee that the accuracy of each valve hole was fixed at a certain value. I told Franco: The machining of valve holes involves drilling, milling, boring, chamfering, and deburring. If these 5 processes are completed in one go, there is no need to worry about accuracy. However, most hydraulic cartridge valve manufacturers need 2-3 times to complete these 5 processes. If there is an error in the fixture or positioning, it will affect the accuracy of the valve hole. You can watch a video of how AAK completes 5 processing steps in one go.
From the video, we can see that AAK processes valve holes using a single clamping machine, which completes the valve hole processing in one go. The details before processing are to set the coordinate system of the machine tool, determine the coordinate values based on the machining data of the valve hole, and then input them into the system. Set the Z-axis value again, select the match tool, and similarly, input the data into the system. The determination of the data twice and the input into the system are crucial, and then the machine tool can be started. The biggest feature of this machine tool is that it is equipped with 7 cutting tools during processing, which can complete 5 processes from drilling, milling, boring, chamfering, and deburring in one go, that is, complete the machining of the hydraulic directional control valve hole in one go. Not only is it efficient, but it also has stable accuracy, as long as there are no errors in the data setting process.
Today, we received the first order from Franco for hydraulic cartridge directional control valves, which took only 3 days from inquiry to order. Although the quantity was only 80 pcs, I believe this is just the beginning for Franco.
AAK hydraulic cartridge directional control valve hole machining, one clamping, complete 5 processes, you can also try a small order!
