Hydraulic flow valve, a kind of cartridge valve, will have the phenomenon of "horn hole" after being used for a period of time, which is a common problem of cartridge valve. The root cause is the processing bottleneck of the cartridge valve combination hole. The processing coaxiality of the cavity hole diameter of these threaded cartridge valve combination holes is 0.03-0.05mm. At the same time, there are machined trace at the transition R angle, resulting in leakage during use. What's more troublesome is that it is easy to cause pollutants outside the cartridge valve to enter the valve spool with the hydraulic oil, causing the whole hydraulic system to strike. Many hydraulic valve manufacturers are used to the domestic market.

AAK has been one step ahead of its peers in the process of cavity hole processing of cartridge valve combination hole. It is programmed by automatic programming software, which replaces the manual programming commonly used by peers. The geometric tolerance of cartridge valve cavity hole has been further improved. The cartridge valve can be processed after automatically generating cavity hole. When semi finishing the cavity hole, the first counter bore is directly machined and no further machining is required, so the geometric tolerance of the cartridge valve cavity hole is improved again. The geometric tolerance of each hole of cartridge valve cavity must be controlled within 0.02mm, which is a hard index. At the same time, each transition angle between the small holes of the cartridge valve is replaced by a small fillet to transition from the common R angle of peers, so as to completely avoid the phenomenon of "horn hole". By optimizing the processing parameters of cartridge hole and upgrading the processing technology of cartridge valve cavity hole, AAK hydraulic valve eliminates the phenomenon of "horn hole" in processing and improves the processing accuracy of cartridge hole.
