| Message: | AAK optimizes the finish machining of the valve body by adopting the finishing process of carbonitriding followed by grinding to precisely control the grinding amount. The manufacturing error model is established, to control the cone angle error of the hydraulic cartridge relief valve cage below 0.06 °, and the grinding tolerance is controlled below 2μm. Although Dante has more than 20 suppliers of hydraulic cartridge relief valves, he resolutely takes AAK as his preferred hydraulic cartridge relief valve supplier. |
