AAK introduced HARDINGE precision CNC lathe, and the machining surface accuracy of hydraulic relief valves was improved to 0.3μm, which can not be reached by nearly 95% of hydraulic valve manufacturers in Ningbo. After comparing the parameters of different factories, a German customer found that only AAK meets their requirements for PO confirmation.  

 

Fred, a hydraulic valve purchaser from Brandenburg, Germany, is in urgent need of purchasing a hydraulic relief valve for a forklift recently. This hydraulic relief valve has a very high precision requirement. The machining surface roughness of conventional valve is generally around 0.8μm, but this one needs to reach 0.3μm, the precision of which is nearly 3 times higher. Fred contacted all his hydraulic relief valve manufacturers, but none of them could achieve an accuracy of 0.3μm. It is difficult for Fred to find a solution.

 

Fred decided to try through B2B. He contacted nearly 10 hydraulic relief valve manufacturers online. Two said they could try it, but they are not sure for 100% success, because they had never made such a high-precision hydraulic relief valve. It seems that Fred has no good choice and asked them to try samples. Three weeks later, due to the insufficient accuracy and stability of the hydraulic relief valve, the customer did not approve the samples from these two manufacturers and asked Fred to re-proofing. Fred had to find other new manufacturers of hydraulic relief valves.

 

Fred saw AAK hydraulic valve on B2B and left a message on our website (www.aakindustry.com): can you make the hydraulic relief valves with accuracy of 0.3μm? I noticed that he browsed AAK website for about half an hour. He should have encountered problem on accuracy. We reply that it depends on the parameter index of the hydraulic relief valve and the working condition requirements. After receiving his drawing, our engineer confirmed that we can reach the accuracy of 0.3μm of this hydraulic relief valve and there may be no 3rd factory who can meet this requirement in Ningbo. If any doubt, we can make samples to test directly.

 

Fred accepted AAK suggestion and paid a sample fee of $1,300.00. Two weeks later, AAK sent the samples of the hydraulic relief valve. After testing, Fred informed that AAK hydraulic relief valve was praised by the customer. Not only did the accuracy of the machined surface meet the standard, but the upper and lower deviation was also very small. While the samples of hydraulic relief valve from last two manufacturers are not stable, some with 0.3μm, some with 0.4μm, or even 0.6μm. Only after comparison, the customer realized that AAK hydraulic relief valve is really high precision, so they have to admire it.

 

The roughness accuracy of the machined surface within 0.3μm is always the hard index of AAK. We have introduced the American HARDINGE precision CNC lathe, which gives us the most powerful support in terms of accuracy. The spindle speed of the machine tool is up to 6000r/min, the radial runout of the spindle 0.0008mm, the positioning accuracy (X/Z) 0.005mm/0.008mm, the repeated positioning accuracy (X/Z) 0.003mm/0.005mm, and the roughness of the machined surface Ra 0.3μm. Turning roundness 0.4μm. Turning cylindricity 0.1μm. At the same time, we upgraded its fixture, with large clamping area and stable processing. Although there are no 2 identical leaves in the forest, there are 2 hydraulic relief valves with the same precision in AAK.

 

AAK hydraulic relief valve with accuracy up to 0.3μm, you can also have a small try!
