AAK Hydraulic Valve Block 3 Features, Peder returns after 6 months

Peder is from Greece. He purchased hydraulic valve blocks from AAK 3 years ago.
He purchased hydraulic valve blocks every 3 months in the first 2 years. There
are ductile iron materials, aluminum blocks and alloy steel (ZG20SiMn), which
have been very smooth. But since the inquiry of a hydraulic valve block last
July, there has been no news. We followed up via emails for several times but
still no reply. Until last week, that’s 6 months later, we received his PO for
100 hydraulic valve blocks, which was quite unexpected.

After communication, we learned that Peder sent the hydraulic valve block order
to another manufacturer after inquiring about it in July last year, because the
price of the hydraulic valve block is 12% cheaper than AAK. But their hydraulic
manifold was complained after 6 months. The hydraulic cartridge valve was stuck
due to the burr residue in the hydraulic valve block, and there were also
complaints that the hole accuracy is not up to standard, and the hydraulic
manifold has leakage. The original hydraulic valve block manufacturer blamed
the hydraulic valve block for its complex oil channel, high processing
difficulty, and difficulty in achieving 100% burr-free. The current accuracy is
their limit. Peder realized that he chose a manufacturer of hydraulic valve
block that is not of high quality.

Peder had to return to AAK hydraulic valve block after 6 months. Because of the
AAK hydraulic valve blocks purchased before, are free of complaints. Even the
complex oil circuit, the burr can be completely removed.

AAK hydraulic valve block has 3 features: no defect, no burr, and 100%
accuracy. The key source is from 3 aspects:

1. When programming, use the tool magazine and tool length compensation
function to make the equipment control more accurate. The processing adopts the
method of one clamp and one top. The mandrel is installed on the three-jaw
chuck of the CNC indexing head, the threaded hole is connected and screwed with
the mandrel, and the left end is supported by the matching tailstock center to
ensure that the center is coaxial with the axis of the mandrel.

2. AAK equipment for producing hydraulic valve blocks: the 5-axis machining
center can automatically and continuously complete the milling, drilling,
boring, tapping and other processes of the hydraulic valve block, which not
only has high efficiency, but also ensures the machining accuracy of the
hydraulic valve block. After processing, use a CMM to check the hole accuracy
to ensure that the accuracy reaches 100%.

3. Deburr and polish without dead angle. The main shaft of the equipment can
swing 360 °, and the burr can be removed no matter it stays in the cross hole
of the hydraulic valve block, or the slender hole, or the blind hole. After
removal, each hole shall be inspected with an industrial endoscope to ensure
100% burr-free.

AAK hydraulic valve block, 3 features. Although it is some more expensive,
there are no complaints. You can also try it!
