AAK Hydraulic Valve Block Large Volume Accuracy within 3μm

Alcander is from Greece. At the beginning of this year, they developed a large
volume hydraulic manifold that requires hydraulic valve blocks. Alcander made 5
samples from a local hydraulic valve block manufacturer, but there was leakage
in the assembled hydraulic manifold. The main reason was the large deviation in
the size accuracy of some holes on the hydraulic valve block. The original
manufacturer shifted the blame, and it is normal for the pore size of the large
volume hydraulic valve block to deviate slightly. Alcander was very helpless.
His boss asked him to search for a new hydraulic valve block manufacturer who
can produce the large volume hydraulic valve block with hole size within
accuracy of ± 5μm. Alcander felt the dissatisfaction of his boss. After
checking with other hydraulic valve block manufacturers for 3 days, none of
them was able to ensure that the accuracy of the pore size of large volume
hydraulic valve blocks can be controlled within ± 5μm.

Alcander searched for "China hydraulic valve block manufacturers" on Google and
found the AAK hydraulic valve block on the homepage. He emailed us to inquiry:
Can the hole size accuracy of large volume hydraulic valve blocks be controlled
within ± 5μm? After communication, it was learned that he encountered
difficulties in purchasing hydraulic valve blocks in their domestic market.
According to his hydraulic valve block drawing, this model has a large volume
and a weight of over 2 tons. Although there are requirements for the accuracy
of the hole size, AAK not only has unique skills in processing, but the key is
that after the hydraulic valve block is processed, there is a large bridge type
laser coordinate measuring instrument to detect the size of each hole in the
hydraulic valve block. Alcander requested AAK to make 5 samples for the
hydraulic valve blocks. After the production drawings were approved, AAK
completed the samples 45 days later.

Last week, Alcander informed us via email that he needs to order 100 hydraulic
valve blocks. I am a bit surprised, this quantity is not small, after all, it
is large volume hydraulic valve block over 2 tons, which also indicates that
the hydraulic valve block of AAK sample has passed the testing. Alcander
provided feedback that their engineers are satisfied with the AAK hydraulic
valve blocks; especially the accuracy of the orifice has reached ± 3μm.

The processing of AAK hydraulic valve block holes is meticulous, and today we
will only share the details of inspection. After the machining of the hole size
of this large hydraulic valve block, a large bridge laser coordinate measuring
instrument was put into use. Adopting the principle of laser interferometry,
the two-dimensional coordinates of the measured object surface are converted
into three-dimensional coordinates through a laser interferometer. This not
only has fast measurement speed, but also high measurement accuracy and no dead
corners. Its XYZ axis measurement range can reach: 2.5m × 2.5m × 2.5m, three
axis adopts natural high-precision granite guide rail, reducing the probability
of error. The error value can be controlled within ± 3μm, which is the
biggest advantage of this measuring instrument. In Ningbo, there are no more
than 3 hydraulic valve block manufacturers who have the 2.5m laser coordinate
measuring instruments.

AAK hydraulic valve block, large volume, with accuracy within 3μm, welcome to
give it a try!
