Consuelo comes from Spain and has been gradually purchasing hydraulic manifold blocks from China in recent years. Recently, they designed a new hydraulic manifold block and wanted to sample it from an old hydraulic manifold supplier in Ningbo China. The manufacturer stated that this hydraulic manifold block has complex oil circuits, high accuracy, and is difficult to process. They are not very confident, but they are willing to try it out. 2 months later, the sample was completed, but the accuracy of the hydraulic manifold block hole was not up to standard, and the hole had hidden burrs. The manufacturer had to give up. Consuelo contacted more than 10 other hydraulic manifolds manufacturers in China, but after a week, there were no results. Consuelo was very upset after wasting more than 2 months of time.
Consuelo found AAK on Google and asked if AAK was able to customize hydraulic manifold blocks with complex oil circuits. After communication, we learned that the accuracy not up to standard and the hidden burrs of the hydraulic manifold blocks produced by the original manufacturer wasted him a lot of time. According to the hydraulic manifold block drawings he provided, most machining centers are powerless. I showed him the irregular hydraulic manifolds with multi channels that AAK exported to Russian market previously. Consuelo may have seen hope and requested AAK to make samples. After 50 days, AAK shipped the test order for the hydraulic manifold blocks.
3 weeks later, Consuelo informed us via email that the AAK hydraulic manifold blocks had been approved by their engineers. After more than 2 months of frustration, he finally resolved it. I told him that for any hydraulic manifolds that require attention, contacting AAK, it may not bother you anymore. If AAK cannot handle it, then there is no need to waste time in the Ningbo area.
The processing of the hydraulic manifold block with complex oil circuits is carried out by AAK using a 4 axis machining center from Okuma, Japan. One clamping can complete multiple processes, avoiding the personal equation of multiple clamping. The machining accuracy of 4 rotating surfaces is controlled within the same range, avoiding the same valve block with different accuracy. Not only can it automatically change tools, but it also has complete tool functions. On this basis, AAK upgraded the drill bit and equipped it with a Taiwan ZOTO water jet drill bit. The drill is sprayed with Cutting fluid during cutting, which not only cools the tool, but also flushes away the chips to prevent burrs. At the same time, we also added TiALN coating on the surface of the drill bit. Compared with other hard alloy drill bits, the cutting performance is more stable, the surface smoothness of the valve hole is good, and the dimensional and positioning accuracy are much higher than other types of alloy drill bits.
The AAK hydraulic manifold block uses a 4-axis + ZOTO water jet drill bit for processing, even the block with complex oil circuits, it is worry free. You can also give it a try.
