Message: | The day before yesterday, someone left a message on the website of hydraulic cartridge valve manufacturer AAK: I have read several AAK articles about valve cage precision machining, and I would like to know how hydraulic cartridge valve manufacturer AAK ensures the machining accuracy of valve spools? From the IP, it should be a competitor of hydraulic cartridge valve manufacturers. My peers would like to see AAK's processing and equipment, even if they imitate the hydraulic cartridge valve manufacturer AAK, but in fact, I do not reject it.
Whether it is a cone type valve spool or a ball type valve spool, machining accuracy is the key. I remember in March this year, Basim from Türkiye met the problem of high-precision valve spool with a peer of hydraulic cartridge valve manufacturers in Ningbo. For 3 samples, the cylindricity of the valve spool hovered between 0.3 and 0.6 µm, and the accuracy was also between 2 and 3 µm. Under the recommendation of a hydraulic cartridge valve manufacturer in Ningbo, Basim contacted AAK. I told Basim that for the cylindricity of valve spool below 0.3 µm and the accuracy controlled within 2 µm, although this requirement is a bit difficult, it can still be achieved in the precision machining process as long as a CNC cylindrical grinder is used and there is precise automatic detection. Basim seemed a bit hesitant, so I went to the workshop and filmed a video of the equipment used by hydraulic cartridge valve manufacturer AAK and how to process the valve spool. After 3 days, Basim requested us to make 12 samples first.
