AAK Hydraulic Cartridge Valve Spool High Precision Machining

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.
