100% deburring of hydraulic valve block, American customer chooses AAK

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.
