AAK Hydraulic Manifold Manufacturer Precision Machining and Testing Tips

Last weekend, Boris from Russia left a message on the website of hydraulic
manifold manufacturer AAK: I have followed your article about valve hole
accuracy 2μm for hydraulic manifolds. How does AAK do the precision
machining? After communication, we learned that Boris is an engineer from a
hydraulic manifold manufacturer in Russia, who also purchases from Chinese
hydraulic manifold manufacturers. Although their supplier also has German
Gehring high-precision CNC honing machines like AAK, there are still a small
number of valve holes that do not meet the accuracy standards, which makes
him very distressed.

This is a very interesting message. Boris seems to be learning from
hydraulic manifold manufacturer AAK and doesn't seem to believe it very
much. I asked Boris if he knows how his supplier checks the accuracy of
valve holes after precision machining. I sent him a video of AAK valve hole
accuracy testing. 3 days later, Boris replied that his original supplier did
not have such testing equipment.

Today, I received his inquiry for a hydraulic manifold, the valve hole
accuracy needs to be controlled within 2μm and with a verticality tolerance
controlled within 5 microns, this may be an appetizer for Boris testing
hydraulic manifold manufacturer AAK. I am very confident in winning a high-
quality hydraulic manifold customer.

How does hydraulic manifold manufacturer AAK detect the accuracy of valve
holes after precision machining? For the testing of this manifold, we use a
Swiss HEXAGON bridge type CMM. The hydraulic manifold is placed on the
testing platform, and the instrument starts working. The probe for testing
is placed on the valve hole. The dimensional accuracy of the valve hole and
the geometric accuracy of the manifold block are controlled through a
program, and the data is presented on the computer screen. The accuracy of
the detection, as well as the geometric accuracy of the hydraulic manifold,
especially the triangular beam bridge design, is more stable during the
detection process. There is also a dovetail guide rail, which is easy to
operate and does not need to worry about human error. Good precision
machining indeed solves the problem of accuracy, but high-precision testing
is still needed. With this dual approach, there is no need to worry about
customer complaints.

Hydraulic manifold manufacturer AAK, with tips for precision machining and
personalized precision testing, you can also give it a try!
