Jeff comes from Israel and has been purchasing hydraulic pressure control valves from China for less than 2 years. At the beginning of this year, a hydraulic pressure control valve with valve seat precision accuracy within 2μm has worried him for over 1 month. This hydraulic pressure control valve is used for hydraulic power units in the aviation industry. The hydraulic pressure control valve sample provided by the original manufacturer showed slight leakage after pressurization. Jeff's engineer found that the valve seat precision accuracy of the manufacturer was around 4μm. Jeff had to search for a new manufacturer of hydraulic pressure control valves.
Jeff left a message on the AAK website: Can AAK control the valve seat precision accuracy of the hydraulic pressure control valve within 2μm? After communication, it was learned that he encountered difficulties in purchasing hydraulic pressure control valves from China. I sent out two models of AAK existing hydraulic pressure control valves the next day for him to test the valve seat precision accuracy. In less than 2 weeks, Jeff said that AAK's valve seat precision accuracy has been recognized by their engineers. He asked us to customize the hydraulic pressure control valve based on their drawings. After 35 days, AAK sent out 30 hydraulic pressure control valves.
Yesterday, Jeff informed us via email that the sample was successful and the hydraulic power unit had been delivered to his client. If without any accidents, they will place a regular order for the hydraulic pressure control valves soon. In fact, the precision accuracy control of the valve seat is not difficult. The original hydraulic pressure control valve manufacturer Jeff found may not have the suitable equipment.
The processing of this hydraulic pressure control valve is carried out by AAK using high-precision lathes of CITIZEN in Japan. Among more than 200 hydraulic valve manufacturers in Ningbo China, there are no more than 4 manufacturers who have this machine tool. Its advantage is that the component processing precision accuracy can reach IT8 to IT6 levels, and the tolerance can be guaranteed to be within 2μm, surface roughness Ra1.6-0.8μm. It is capable of achieving point control, with a spindle speed range of 300~10000r/min, its travel parameters can be controlled at 200mm/min. The most crucial thing is that the driving method of the back spindle adopts a built-in motor, which achieves the spindle speed range of 10000r/min and also improves the production efficiency of the hydraulic pressure control valve.
