AAK Hydraulic Flow Control Valve Accuracy within 2μm

Maddox comes from Turkey and purchases many hydraulic flow control valves from
Ningbo China every year. At the beginning of this year, a hydraulic flow
control valve with hole accuracy requirement of within 2μm exhausted him.
Their client was developing a hydraulic power unit in the aviation industry
that requires the use of hydraulic flow control valves. Maddox still made
samples from a hydraulic flow control valve manufacturer in Ningbo, but it
didn't go smoothly. It took 75 days for the original manufacturer to adjust the
valve hole accuracy twice, but it still couldn't meet the 2μm accuracy
standard. The best accuracy can only be at 3μm. The customer has pushed the
progress of the hydraulic flow control valve several times. Maddox realized
that relying solely on the original manufacturer is difficult to achieve good
results. After contacting several other hydraulic valve manufacturers in China,
there is still no one who can guarantee the accuracy of the hydraulic flow
control valve within 2μm, it takes time to make adjustments, Maddox was very
anxious.

Maddox contacted me through the introduction of other hydraulic valve
colleagues in Ningbo. According to his machining drawings for hydraulic flow
control valves, most of the processes are not difficult, but the precision
machining of the valve holes for hydraulic flow control valves is difficult,
especially with an accuracy of within 2μm, this not only requires good
equipment, but also requires experienced technicians. I provided a high-
precision hydraulic flow control valve case from a Canadian client for his
reference.

Maddox paid for the development fee the next day, and requested AAK to make
samples. After 45 days, AAK sent out 30 hydraulic flow control valves. 2 weeks
later, Maddox informed us that with AAK hydraulic flow control valve, their
aviation hydraulic power unit can now work, which means that the function of
AAK hydraulic flow control valve has been recognized by the customer. Maddox
asked me to patiently wait for the bulk order, which should be placed no more
than 3 months.

For this hydraulic flow control valve, AAK adopts a high-precision CNC lathe
from Japan, and machine tools for processing military products. The encoder can
be used for position measurement and can compensate for errors caused by tool
wear and other reasons. At the same time, the ball screw is driven by a driving
motor. The ball screw is pre tensioned and installed for interference, and
there is no gap during the transmission process, ensuring that the accuracy
tolerance is stable and within 2μm.

AAK hydraulic flow control valve, accuracy within 2μm, you can also give it a
try.
