For hydraulic cartridge valves with high requirements, AAK produces them using 5-axis CNC machine tools

China [CN]

Luca from Germany left a message on the website of hydraulic cartridge valve manufacturer AAK last Friday: Can AAK use 5-axis machine tool to produce valve cage for hydraulic cartridge valves? Luca conveyed 2 questions: whether AAK has a 5-axis machine tool and the valve cage of the hydraulic cartridge valve that he needs, is some particular.

It is rare for us to receive this type of messages: using the equipment to delineate the production of cages for hydraulic cartridge valves. After communication, it was found that the hydraulic cartridge valves are to be used in their newly developed manifolds, with high precision requirements for the valve cage, which cannot exceed 2μm tolerance. In order to help the hydraulic cartridge valve manufacturer better understand his requirements, the production equipment was delineated in the inquiry, which posed a great challenge to the hydraulic cartridge valve manufacturers. The manufacturers without this equipment will be eliminated in the first round of selection.

I remember that we took a video last year about the production of hydraulic cartridge valve cages by using DMG 5-axis CNC machine tool. At that time, it was a customized hydraulic cartridge valve for an Israeli customer. For the hydraulic cartridge valve with particular requirements for the cage, AAK used a German DMG 5-axis CNC machine tool. Its stable numerical control technology and stable accuracy were favored as treasures by our engineers. The processing speed reaches 20,000 rpm, with 5-axis linkage processing and equipped with a 30 position tool library. Its driving method is a direct drive ball screw drive, and all shafts adopt a linear direct measurement system to ensure that the valve cage processing accuracy is within 2μm. From the video, we can see that the technician first cleans the fixture with an air gun, then installs the hydraulic cartridge valve cage blank into the fixture, and then starts the machine tool. After processing, each valve cage needs to be measured and checked with a plug gauge. If the accuracy of the valve cage is qualified, it can be cleaned again with an air gun and then transferred to the next production process.

After we sent this video to the German customer yesterday, he sent us the inquiry for a customized hydraulic cartridge valve today, with a very detailed drawing, which made us feel the rigor and professionalism of German customers again. How could it be possible for a hydraulic cartridge valve manufacturer to have no improvements if cooperating with such type of customers? This is also the benefit for hydraulic cartridge valve manufacturers working with customers with high quality requirements.

AAK hydraulic cartridge valves, 5-axis equipment is ready for you, you can also try it out!
