AAK Hydraulic Cartridge Valve Cage High Accuracy Surface Finish Grinding

Recently, an IP from Germany left a message on the website of hydraulic
cartridge valve manufacturer AAK: Can AAK process a hydraulic cartridge
valve with the surface finish of the valve cage controlled within Ra0.2μm
and with a dimensional accuracy tolerance within 0.5μm? I was a little
pleasantly surprised to see this message because:

1. There are not many inquiries from German customers regarding hydraulic
cartridge valves, although hydraulic cartridge valve manufacturer AAK has
supplied more than 30 countries, this should be the third German customer's
inquiry.

2. Not many customers seem to have special requirements for the surface
finish of hydraulic cartridge valve cage.

After 3 rounds of communication, I learned that Frank is a procurement
engineer for hydraulic equipment company. Currently, he is in the trial
stage to purchase from hydraulic cartridge valve manufacturers in China and
is not very satisfied with the details of Chinese hydraulic cartridge valve
manufacturers. Frank consulted 6 hydraulic cartridge valve manufacturers in
China, but none of them was unable to guarantee his requirements on the
valve cage. The order that Frank tried is a standard part of SUN hydraulic
cartridge valves, but the requirements are higher than SUN's. AAK re-
optimized the production process and equipped specialized equipment to
ensure Frank's requirements for hydraulic cartridge valve cages. At this
point, some of our old equipment, old technicians, are put to use. After 20
days, 30 hydraulic cartridge valves were sent out. 1 week after receiving
the samples, Frank recognized the hydraulic cartridge valve cage processed
by AAK, which met his requirements.

We use a TOYODA cylindrical grinder from Japan to process the valve cage for
this model. Although this grinder has been in AAK for 10 years and has a
somewhat shabby appearance, it is the treasure of our veteran technicians,
and we optimize the equipment every 2 years. Its stable grinding accuracy is
the biggest advantage, not only high accuracy, but also stability,
especially low vibration bed and high-precision feed mechanism, combined
with specialized cutting fluid. The machined hydraulic cartridge valve cage
has a clear contour and a surface finish of within Ra0.2μm, the dimensional
accuracy tolerance is within 0.5μm.

Why can the hydraulic cartridge valves provided by AAK meet the requirements
of the German customer, while other 6 Chinese hydraulic cartridge valve
manufacturers are uncertain? Because:

1. AAK adopts equipment from the Japanese military industry and also
upgrades local functions. I don't know which hydraulic cartridge valve
manufacturers in Ningbo often have these actions.
2. The experienced technician from hydraulic cartridge valve manufacturer
AAK has over 30 years of industry experience.
3. For hydraulic cartridge valves with special requirements, AAK has the
ability to re optimize production processes and pay attention to details.

AAK hydraulic cartridge valves, meets special requirements, and German
customers are purchasing it. You can also try it out.
