AAK uses endoscope C50 to detect the internal burr of the hydraulic valve block, and then sprays the burr remaining in the hydraulic valve block with high-pressure solution, so that there is nowhere for the burr to hide. Nearly 95% of domestic hydraulic valve manufacturers are not equipped with endoscope and ignore 100% removal of the residual burr of the hydraulic valve block. The American customer who has suffered a loss elsewhere chose to order from AAK again.  

 

Most domestic hydraulic valve manufacturers use conventional physical methods to deal with the burr of hydraulic valve block, and check whether the burr is cleaned by experience, especially the burr of deep hole or magnetic burr, which can hardly be cleaned. It is common that the defective rate of hydraulic valve block exceeds the standard due to human error.

 

At the beginning of last year, we received an inquiry for hydraulic valve block from Hunter, an American customer. We calculated the price according to his hydraulic valve block drawings. Hunter was not satisfied with our quotation. Because the communication was very pleasant, I wanted to make friends with hunter and gave up my commission to adjust the price. Hunter frankly said that although the new price of AAK hydraulic valve block meets his target price, the prices of other hydraulic valve manufacturers are still cheaper than those of AAK. We can only withdraw from the purchase of hydraulic valve block amicably.

 

If something goes unusual, there will be problems. 2 months later, Hunter came back to us and said that he was very willing to accept our quotation for hydraulic valve block. He informed that there were different degrees of burrs at the internal cross holes of the hydraulic valve block samples proofed by the original hydraulic valve manufacturer. The hydraulic valve block samples were modified 3 times. Each time the cartridge valve was installed and debugged, the valve spool was stuck from time to time. The factory has also conducted commissioning for many times, and has been unable to remove burrs for 100%. He can only give up this hydraulic valve manufacturer and came back to AAK.

 

Burr must be produced in the drilling process of hydraulic valve block, which is very harmful to the hydraulic system. In addition to adopting appropriate treatment process for burr removal, it is also necessary to have relevant auxiliary testing equipment to guarantee the complete 100% removal of burr. Hunter asked us to arrange approval samples of hydraulic valve block immediately. After 15 days, we sent the hydraulic valve block samples. On the 3rd day after Hunter received the samples, he sent an email to inform AAK that the samples passed testing at one time.

 

Hunter admired that AAK can get the hydraulic valve block samples approved at one time that the peer can't get approval at 3 times. At the same time, he also expressed his curiosity about how AAK can accurately remove the burrs? Because this hydraulic valve block has many internal cross holes and deep holes. Firstly, the accurate position of burr in the hole must be found, and then the burr shall be removed by high-pressure solution jet. Then, AAK has one more process than peers, using endoscope C50 to recheck the subsequent residual burr. If there is still residual burr, it shall be cleaned and rechecked again until it is completely eliminated. This is the detail awareness lacked by other hydraulic valve manufacturers, and also the reason that AAK can achieve 100% deburring.

 

Details make a difference. AAK concentrates on details, strives for perfection. You can purchase at ease, use at ease for all types of hydraulic valves produced by AAK.
