AAK Hydraulic Needle Valve High Precision No Jamming

At the beginning of this year, Samuel asked by email about the production time
of 1,000 hydraulic needle valves, He specially emphasized that the technical
parameters of the hydraulic needle valves need to be the same as those samples
made before, especially the valve hole accuracy must be 100% within 1μm or
less. Samuel has been cooperating with AAK for 3 years. It is the first time
that he deliberately emphasized as such in email. After communication, I
learned that the hydraulic needle valves that AAK made samples for last time
was 20% higher than that of other hydraulic valve manufacturers, so he placed
the order with another manufacturer. However, now this batch of hydraulic
needle valves have been complained by customers that the hydraulic winch is
stuck. The root cause is that the accuracy of the hydraulic needle valve holes
is uneven, and some are less than 1μm, and some higher than 1μm. After the
original hydraulic needle valves were replaced by the manufacturer, complaints
still continued. The boss was very dissatisfied with Samuel's purchase this
time and asked him to source another hydraulic needle valve supplier.

Samuel can only get back to AAK, because the sample accuracy of AAK hydraulic
needle valve hole was 1μm or less. I told Samuel that the shipment of AAK
hydraulic needle valves has never been lower than the sample standard. The next
day, Samuel sent us the PO of 1,000 hydraulic needle valves. After 45 days, AAK
delivered 1,000 hydraulic needle valves.

Last week, Samuel sent an email saying that AAK hydraulic needle valves had
been installed on the equipment for more than half a year, and no complaint was
received. His boss would rather spend 20% more cost and must purchase the
hydraulic needle valves with valve hole accuracy 1 μm for 100%. I told him
that even if AAK hydraulic needle valve is used properly in another year, it
will not get stuck.

Samuel was surprised at how AAK ensured 100% accuracy of the hydraulic needle
valve hole within 1μm? For the control of the manufacturing quality of
hydraulic needle valves, AAK's 3 characteristics lead the majority of hydraulic
valve manufacturers.
1. On the processing equipment, the valve hole is finished with the TAMIX one-
time tool walking high-speed ultra precision honing mill imported from Japan,
which is thoroughly ground without traces. In mass production, the wear-
resistant SPA tool effectively ensures the stability of processing, and the
valve hole accuracy is guaranteed to be 0.8-1.0μm and the surface roughness
reaches Ra0.2-0.3.

2. In the processing process, AAK has more than 10 years of experienced
technicians with special machines and special personnel, who have engraved the
dimensional accuracy of each element in their minds.

3. In terms of processing and inspection, after the valve hole is processed,
Diatest small pore diameter high-precision measuring instrument imported from
Germany is used to accurately measure each hydraulic needle valve hole, and the
minimum measurement accuracy range can reach 0.1μm so as to ensure that the
accuracy of each product meets the standard.
